[TRANSCRIPT CONTINUED FROM DESCRIPTION] Erin Schliep: Yeah. In fact, entirely. It really stemmed off. And that's where the opportunities came to me when I first started out. But also that's the areas that my friends are in. And so there's a lot of connection between the statistics department, the math department, and their graduate degree program in ecology at Colorado State in particular. And so that's just sort of where my cohort of friends and people that I knew were in, and my interest sort of stemmed from their interest in many ways. But I think being outdoors and likeminded with that group of people, it just became a natural fit. Lara Harmon: Colorado is a very outdoors place. Erin Schliep: Yes, exactly, very much so. Lara Harmon: Okay, are you ready for the next one? Alright, is there a class or classes that you didn't take in college that you wished you had? Erin Schliep: Yeah. So as I just got done saying, with my double major I ended up spending a lot of time taking accounting and business classes in general, and so I I definitely did not have the opportunity to take as many outside of my degree area classes as I would've liked. But I recently went back through the Gustavus Adolphus course listings, so I know that there are definitely some departments that I'd be interested in. And particularly within, say, the environmental studies or atmospheric sciences, I came across two classes I thought would have been fantastic, at least knowing what I wish I knew coming into what I'm doing now. One of the classes was a class in surface processes, so it looked at like weather systems and streams and glaciers, groundwater, ground ice, tectonics, volcanoes, etc. And again that would open up a big picture of things that are happening on the Earth, and I think just knowing how some of those processes exist and how they've been changing would be a big thing to know as I have continued in this realm of environmental stats. The second one-it may be even more closely applicable-was a class in remote sensing. And so a lot of the statistical methods that I've worked with my collaborators in developing have used data from remote-sensing technologies. And so one of the important things in stats is not only knowing how to write down the model in a [uncertain of word] inference but also understanding how the data were obtained. Because that's a big component of when you start specifying, right? These are sort of the modeling parameters and the uncertainties associated with the data that was being collected. And so having a broader knowledge on different types of remote sensing would have been extremely useful and right into that comes some of the software and the GIS technology and such that I think would have been useful 15 years ago. Lara Harmon: So you mentioned GIS. Could you briefly name a few remote-sensing tools just so we have an idea, if no one knows. Erin Schliep: Yeah, yeah, yeah, great. So they could be things like LIDAR or other sort of devices that fly underneath the bottom of airplanes as they go across fields and are surveying forest or agricultural land, for example. But also other ones would be that are on satellites. So, Earth-orbiting satellites that are observing so many different Earth and surface processes in terms of temperature and water temperature, sea surface temperature, and obviously the air quality metrics, different ozone concentrations, etc. All of those things that I've worked in as a statistician, but it would have been great and it would've been easier than learning on the fly as I have how these technologies are in fact used. And that knowledge could be incorporated into the statistical side of the equation for sure. Lara Harmon: Thank you. It always changes, what's being used. Ready for the next one? Yep, okay, what does a day in your life look like? A workday, I'm assuming. Erin Schliep: Yeah, absolutely. Ever since living in Colorado, I'm a bike-to-work person, so it starts, off with a bike ride into the office, and then depending on whether it's a teaching day or a non-teaching day is a little bit different, but I teach primarily on Tuesdays and Thursdays. So Tuesdays and Thursdays are my teaching days where I have office hours and meetings with students in my class, and obviously, then my classroom time. Non-teaching days are usually either meeting days or days that I preserved for my own research. And so that's a major very important aspect, especially as an early career statistician, is making sure to preserve your time to get research done that's uninterrupted time. So it's easiest if you have a big block of time where you don't have, you know, an every other hour schedule of meetings where you can get nothing done between those meetings. So depending on the day, if it's a Wednesday, that's primarily my research day, and so I try to lock myself in on those days and avoid as much email and contact with students and other faculty meetings as I possibly can. But otherwise, yeah, it's been really giving my lectures or preparing my lectures or getting ready homework assignments or things for my actual class, and then having meetings with collaborators. And so those days, usually I currently have a collaborator, he's both here at Mizzou but also across the nation and sometimes across the world depending on where people are traveling to, so there's a lot of Zoom calls and Skype phone calls and big group collaborative projects where right now it's the three of us on the Zoom call, but sometimes we have 30 of us on a Zoom call. So trying to organize how some of these big NSF [National Science Foundation] projects are moving forward also definitely fills up some of my time. Donna LaLonde: Erin could you say a little bit more about one of the cooler projects that you're working on? Share a bit more with us about what the project is? Erin Schliep: Yeah. So one of the big NSF-funded projects that I'm on is studying lake water quality in inland lakes across the United States. And so the first page of the project is collecting data from literally like 160 thousand lakes across the United States and bringing this into a big database that has the measured nutrients like nitrogen and phosphorus, for example, in these lakes, as well as the surrounding area, that could be leading to changes in how these lake nutrients are varying through time. So things like land use, for example, or temperature are primarily the things that are affecting those different nutrients And so, yeah, this project is looking at taking the operations that we have spanning, I think, the number is 87 different agencies that have gone about collecting this data. So you have the government agencies and academic institutions, and then also local tribes that have collected some of the data. So bringing them all together and then trying to pull them is a collective effort in order to see how these things are changing or how they're varying across the landscape. And for those lakes that we're unable to visit, is there information from the ones that we are that can be used to predict the ones that we aren't? So it's sort of this big collaboration between limnologists or those who study lakes by some of the ecologists and then statisticians and computer scientists come together to try to get information about lake nutrients and possible ways that they might be changing under different climate change scenarios.

[TRANSCRIPT CONTINUES] Donna LaLonde: So how is it that you learn enough ecology to collaborate? Right, so I'm just always amazed at the language that there is within a specific domain. So how do you learn to talk to your collaborators? Erin Schliep: Yeah, sometimes I'm more successful than others, that's for sure. But you really have to want to be able to communicate, right? Because with those that are outside statistics, there are some statistics words that I definitely don't use when I'm communicating with them, and there's obviously things that in their world that they're not going to say to me, because I'm not going to understand it. But just continually asking questions. It's a back and forth. 'I don't know what you're saying,' and being comfortable saying 'I have no idea what you're talking about' just to be able to get them to explain it on a different level. And you have this in teaching as well, right, you have to read your audience and what parts are they picking up, where are they having questions, to try to explain it again and sometimes again and again. And I'd be the first to admit that in a lot of these topics... Had you asked me this before this project started, I knew nothing about nitrogen and phosphorus and lakes, right? So now I'm slowly picking up some of the terminology with nitrogen cycling and the importance of agricultural land, how it changes the levels of these nutrients. Just even the way that the data is being collected. For example, Secchi disks. It's literally a bull's-eyelooking disk that they drop into the lake when they're out on a canoe and they measure how far it goes down before they can no longer see it. Alright, so, that's the depth, right? Secchi disk depth, is what the column is listed as in my dataset, but had I not known that, that was just another variable. It's just from being interested in wanting to continue to learn. Like I love learning about some of these things I never would have explored prior to now. These are even things that you might not have learned just in your traditional environmental studies or environmental science classes. Because just some of it you learn when you're in the field. And I consider some of my collaborative conversations like being in the field. They're learning about some of these different technologies and different ways that they just talk about it. Lara Harmon: I love the tools scientists use. It's always really interesting to figure out how they do actually do stuff. Erin Schliep: Yeah, absolutely, yeah, and in practice, right? You ask them, you know, how accurate is that really and usually they have a pretty good answer on either, 'oh, pretty accurate' or 'ehhhh.' Some people are better than others. Lara Harmon: That's cool. I love that you just have to watch it. You're like, hm, can't see it. Alright, Donna, do you have any more questions before we move on? Donna LaLonde: Well, this is totally off the topic of statistics, but as a cyclist I'm really curious how far is your bike commute and what do you ride? Erin Schliep: Ah, great question, yeah. So my bike commute is currently about three miles up one very big hill on the way in and down one very big hill on the way home. Right now I just have a commuter bike, a Cannondale Quick 4 to be exact, but on the weekends when I actually have time to get out, I ride a Cannondale CAAD 10 road bike, so I'm of the Cannondale fleet right now. Donna LaLonde: Good choice. Lara Harmon: Alright, ready for the next one? Okay, so we've kind of moved a little bit into this, I think, but what is the coolest thing about your work and your research? Erin Schliep: Yeah, so we touched on that a little bit, because I think you can recognize I'm passionate about the collaborations and just learning about the different areas of science that statisticians are currently being involved in. Again, mine are primarily focused on environmental applications but they definitely wouldn't need to be. So some of these collaborations span from during my postdoc, I was working-sorry, my graduate degree, I was working on understanding or evaluating the condition of wetlands in northern Colorado. I've done some projects with people that are looking at social behaviors of dolphins and whales. Again, I don't know a lot about dolphins and whales other than what I've learned about through that project. A lot of the work I did when I was at Duke was looking at estimating carbon in forests in North Carolina. Another big project that I worked on in North Carolina was these people at NC State set up a bunch of camera traps, and these camera traps take pictures whenever an animal walks in front of it. And so it's a citizen science project where then people go in and they identify what species of animal it was. And they're interested in understanding whether or not different species were co-occurring, meaning that these species actually see each other on a day-to-day basis. We talked a little bit about the nitrogen examples. So I've talked with a lot of people that are studying limnology and I have collaborators up in Minnesota looking at fish populations, and so predator/prey fish populations and how those might be changing in some of the Great Lakes and the Midwest or Upper Midwest. And then those projects that stem from looking at air quality metrics from satellite data, right? So, again, there are so many different areas that statisticians can get their hands in, and you just continue to learn about areas of science that are so interesting. And you can still be passionate from the statistics side, you can apply it to whatever area you're just interested in. Out of all those projects, probably if I had to pick a favorite, and again I don't know if I can pick a favorite based on purely the stats behind it, but whenever you get the opportunity to visit a research site, that's fun, right? So now you can just see actually on the ground where these scientists are doing their studies, right? Where are their field sites? And so our team went down to Puerto Rico for a week during the winter-our winter-and it was beautiful, and we got to explore the environmental gradient across the island, right? You have the extreme sort of high precipitation regions in the Northeast, where there's the very dry region in the south. You can see how the vegetation there varies dramatically based on that elevation change and really how the systems come across that particular region. And so when we were there it was about a year and a half before the hurricane came through. And so after that hurricane, we were able to see some of the pictures afterwards and you really saw the devastation of the island that it incurred in that big hurricane. So again this sort of travel aspect, but in getting an opportunity to actually now spend time in the field with your collaborators that really know the environment and just get to tag along with them, that's pretty fun. Lara Harmon: I know someone who does that, so I've heard those stories. It always does sound like a lot of fun. Erin Schliep: Yeah, I don't know how long I would survive at a field research station, yeah. Cold showers only go so far for me. But it was definitely fun for the week that we were down there. Lara Harmon: And I just love to hear about scientists from non-scientists perspectives, and what they get up to. [TRANSCRIPT CONTINUES IN REPLY]

[TRANSCRIPT CONTINUES] Erin Schliep: It was an experience. We were out on a hike one day and a tree limb broke off of a tree that was near where we had been staying and it fell across the rental car, so there's a huge dent across the hood of the car. You get the whole experience of non-outdoor scientists... Lara Harmon: Yeah, I meant to say that. Non-field scientists and field scientists. Erin Schliep: And I was one of them. It was good, though. It actually makes you really understand what you're doing on a completely different level. And so really I would argue all statisticians should have a field day with every project if it's possible, to really see exactly how this process works. And that's actually some of the advice that I got from my adviser Jennifer Hoeting back in Colorado. She was getting opportunities to go out and tag the deer when they're studying chronic wasting disease. So now they're flying in on a helicopter and they're dropping down and they're collecting the data and they're tagging the animals. And this is not something you necessarily need to do to be a statistician, but I think it makes you really appreciate when you start questioning why they didn't do a better job collecting their data, you appreciate that it's not always possible to do so. Lara Harmon: I think that sounds like quite good advice, to have a perspective from all levels. Erin Schliep: Yeah, especially if you like to be outside, yes. Another reason why I'm in the environmental stats world. Lara Harmon: Makes sense. Alright, Donna, do you have any extra questions? Donna LaLonde: Nope, I'm good now, thank you. Lara Harmon: Alright, are you ready for the next one? Oh, I think we have covered a little bit of this one, as well. So what do you like to do when you are not working on research or teaching? Erin Schliep: Yeah, or riding my bike, yeah. I think just literally being outside and being active is what I do most of the time when I'm not sitting literally in this chair teaching my students. And so that includes biking, but running, hiking-I did a lot of hiking when I lived in Colorado, and even actually here in Missouri we have some nice hiking trails. I'm actually a golfer, so I spend quite a bit of time on the golf course when I can get away for an entire Saturday. It's a little bit harder for me to do right now then just going out for a quick run or bike ride, but playing golf is actually a passion of mine, as well. Donna LaLonde: Do you compete, Erin? Any running racing , or cycling racing, or duathlon, triathlons? Erin Schliep: Yeah, so I'm primarily a runner, when it comes to racing, and so I would say the half-marathon is probably a favorite. But I did run my first marathon-first two marathons, I guess-in 2018, and I'm looking forward to not running another one this year. But it was good. It was a great experience, and I think it's just if you are passionate about running, it's great to get outside. I actually do the sports of the triathlon, so I like to enjoy swimming and biking and running. But I've never actually competed and put them all together. I'm still a little bit terrified of the whole changing transition idea, but it will happen. It just hasn't happened yet. Donna LaLonde: So as a runner, I just have to ask, where were the marathons? Erin Schliep: Great question. So I grew up in Minnesota, and my parents met at University of Minnesota, Duluth, and so the first marathon I did was Grandma's Marathon up in Duluth, Minnesota. So that was just this past June. And about a month prior to that, roped in with some friends, here in Missouri I ran the Berryman Trail in south-central Missouri, part of the Ozark Trail. So that was a completely different experience, all single-track trail for 26.2 miles .At the end of that one I also said, I think this is a never again for me. But you never know. Again, it's fun. You're outside, you're being active, and so it's hard for me to say no to those types of things if the opportunity should come around again. Donna LaLonde: Yeah, I understand. The Grandma's Course is very beautiful, so that's wonderful. Erin Schliep: Yeah, interestingly enough, that's one of those races where you run right along Lake Superior the entire way. And probably about mile 16, you see the bridge which is downtown Duluth, and that's sort of the iconic sort of symbol of Duluth, and you see it for 10 miles running toward it. Although the marathon 2018, it was 50 degrees and foggy. Never saw the bridge, barely saw the lake, and so, totally different. Don't know if that's helped or hurt that. So the running conditions, the temperature was perfect, but it wasn't maybe the exact experience that people have had in the past. Maybe why I'm thinking about doing it again but, again, not this year. Lara Harmon: I've watched runners get other people to run. It's hard to say no. Erin Schliep: It very much is. It's easy to get people to commit to it because you just tell them how great it's going to be and the competitive nature I think jumps in that you're like, okay, let's all just do it, and you sign up, and now you're doing back-to-back races and the excitement gets you there and the adrenaline gets you there. Lara Harmon: Donna, do you have more questions? Donna LaLonde: I am not going to start down the running path or we would be talking about our favorite races for the rest of the day. Although I have to say that I'm liking the trails a lot these days, so I totally advocate another trail race for you. Erin Schliep: Yeah, absolutely. It's a different deal altogether, a different mentality, different competitive component to it. I definitely don't race those as seriously as I would race a road race, so it's much more for the social aspect for me and I think that's probably a healthy way as we get older Lara Harmon: Okay, are you ready for the last one? Okay, what question that we didn't ask would you like to answer? Erin Schliep: Yes, so the one thing I think that's important to know is that even though this entire interview or discussion so far I've been talking about environmental statistics, you definitely as a student or as someone coming up into this career of statistics and applied statistics in general, is that you definitely don't need to stick to one. And it's interesting how similar they are. The question would be are there opportunities for statisticians to work in more than one area? So not just, say, environmental statistics. And the answer is absolutely yes. And it's amazing to me even as I have continued my career to see some of the connections from different areas. We have, obviously, seminar speakers come through the academic setting all the time. You see some talks that aren't in your application area that are definitely tied to or somehow tangentially related. And so some of the work that I've done with, say, dolphins and whales borrows from the idea of social networks, which then extends into looking at Facebook and Twitter and how those sort of social networks have evolved or changed through time. Currently at Mizzou we're working on developing a sports analytics program. And so you might say, environment, sports, right, I don't see the connection. But think about animal movement models. We watch geese fly, right? We watch animals move across the landscape, and they're responding to one another. Same thing as soccer players as they run around a soccer field, alright? So how can we borrow and look at some of the models and methods that we've used from one area and notice that they directly apply to other areas. Looking at some sort of different objective, where animals might be trying to pursue higher ground or food, and soccer players are trying to get a ball into a goal, alright? And so a lot of these areas, it really simmers down to take that maybe one step further. Much of the methods that have been developed even in the past 10 to 15 years in spatial and spatial temporal stats have dealt with big data, so high frequency time series data or spatial temporal data that have been collected and how to monitor those or model them. And you can take that and now think about athletes. And you've got the GPS trackers on them, you've got their heart rate monitors on them. There again is a high frequency time series data on these individuals as they run around a soccer field, and how their heart rate or other biometrical things are responding. That extends right into precision medicine, right? How should we be training our athletes in order to tailor their programs and their covering to increase the performance of both the individual and the team. And so there are so many connections between all these different areas as you start learning more and sort of building up this toolbox of methods and models to use with them. It's very easy to start seeing some of the connections. So there's no reason to just stay in environmental stats if you have passions across as many areas as you want. So I'd sort of argue that if I wanted to get back into accounting there are ways to start thinking about the current experience I have right now with, you know, forest biomass, right? Some of the methods and models and things I've learned from these particular experiences and opportunities, I think, can directly relate into another future collaboration that might come knocking on the door.

[TRANSCRIPT CONTINUES] Donna LaLonde: So, Erin, as you're describing these various projects, that actually makes me think about a question about-it's clear that that you use computational tools, and you talked about database, and So I'm wondering if you have any advice for folks in terms of, like, programming languages, database skills, that that they should acquire early on in their career. Erin Schliep: Yeah, so it's interesting. I mean, the times have definitely changed. When I graduated with my undergrad, I had never programmed up just a traditional regression model using software at all. The times have definitely changed. Our undergraduate students now are being sort of thrown at R and SAS and all the different tools like that. I say, currently, at least in the academic setting, R as a computing language is probably the most important, but really if you know one or you have the ability or you've experienced learning one, I'd like to say you could more easily-I don't say easily, but more easily-pick up a second and a third and a fourth... And it seems like right now I would probably argue that Python is becoming one of the most popular second or third languages to be learned. But again it depends on what your future direction is going to be. I know that SAS is still a big component when you think about from the medical arena or even industry jobs definitely want to see some SAS experience. And so I definitely would focus on just one, but start building up at least the walking knowledge of a few more if you can. But particularly as an undergrad if you walk out of undergrad feeling pretty comfortable in one language, I think throughout your graduate career you'll be able to learn the other ones as you go and as you need to. Again C or C++ definitely comes into play with big computing, but I think Python is really maybe where that's turning now. Lara Harmon: That's a constant topic of discussion that I see in our online community and elsewhere. Which languages to use and learn and for what. Erin Schliep: Yeah, and it's actually hard, and we talk about that even as a faculty a lot, of what languages we should be teaching our courses in. Because again if you're going to stay in academia, R sort of seems to be the one, and again, Python as an extension would be great, but if you're going industry or government than SAS becomes the way. And tailoring your classes appropriately becomes sort of an important aspect, as well. Donna LaLonde: So that makes me think we should have asked what's your favorite class to teach. Erin Schliep: Oh, wow, great, yeah. Oh, good one. Donna LaLonde: Like picking your favorite child, right? No? Erin Schliep: No, not at all, not at all. I really like teaching the applied regression classes. So applying your models, statistical models. Currently I'm teaching spatial stats, which, again, is where some of my research interest and passion lies, and so that's obviously been just a fun class to teach, just because I have a lot of the examples that I've mentioned while talking to you all that fall in that area. But just I would argue that the applied statistical modeling class is probably my favorite. And it's an Rbased class and so some students have some R experience and some of them are brand new, and so it's definitely a challenging class. The teacher in that aspect is giving enough example code to see what we're trying to do. But definitely it's not a matter of just hitting run on the code to make it work, it still takes the students quite a bit of time and effort to get the code tailored towards what they're needing to do in their labs and in their homework assignments, yeah. But I think maybe not in terms of particular class, but just in terms of students, I teach a lot of undergraduates and a lot of graduate students, non-statistics-seeking students, so I have a lot of masters and PhD students from the environmental sciences and really just across the university-quantitative psychology, etc. And so it's been fun to also then just continue to extend some of these collaborations and learn about what they're working on, as well. And so that's just been a fun way to meet more people across campus. Donna LaLonde: Well, this has been great! Thank you so much. Erin Schliep: Absolutely. Thank you for taking the time to chat with me. [END TRANSCRIPT]

[TRANSCRIPT CONTINUED FROM DESCRIPTION] And so needless to say when I came home and I told my mom and my dad that I wanted to switch my major to math, they both looked at me like I was crazy. They were like, what are you gonna do with that. And so, I'm first-generation, and so my folks, they're from the islands. Like I said, my mom was a banker and my dad does home remodeling, so math is the furthest thing from anyone in my family. But I made the switch, and I continued on in the math program at Drexel, and I went into the master's program at Drexel, as well. It was a two-year master's program in math, and that's when I found out about biostatistics. And so halfway through my program when I was thinking about what to do next, biostatistics was-I was convinced that this is this is really what I wanted to do, because I love math but I didn't love the pure side of math, I love the applied side of math. And so I like the blending of health and math or biology and math. And so when I was thinking about different schools I applied to different PhD biostat programs around the country. I really wanted to stay in Philly, though, that was my goal. Because I was from Philly, I was comfortable in Philly, and I just wanted to stay in Philly. And I had a mentor at the time who-this was during the era of hand-writing letters of recommendation, okay. So I had approached her, my mentor, she was a faculty member in the math department and she wrote my letters of recommendations for different PhD programs. But then she told me I forgot one, and I said, no, I didn't forget one. I was thumbing through the recommendations, and she said, you forgot Harvard, and I said, no, I didn't forget Harvard, that just wasn't on my list. And she said well,why? And she said, they have a really strong biostats program that's what you want to do, you should really consider it. And I said, well, I didn't really think Harvard was a place for someone like me. And so she just looked at me square in the face and said ,you need to make it a place for someone like you. And so I applied and I got in and I never looked back. And it was the best set up, it completely changed my thought of the stereotypes I had in my mind about a place like Harvard and about-even within the School of Public Health, because as a math student you're not housed typically in anything Public Health, you're housed within Arts and Sciences, and so it's a very different type of culture. And so that's how I ended up finishing up my training in in biostatistics. Immediately after I defended-literally the next week, I was working at Drexel. And so that's how I ended up in now this faculty position, and I love it. Donna LaLonde: So, ultimately back in Philly which is good, right? Loni Tabb: Ultimately back in Philly. [laughs] Donna LaLonde: So, I'll ask both of you. If there was a class or classes as an undergrad, in your undergraduate career, that you didn't take that now you wished you had. And I'll start with you, Loni. Loni Tabb: Yeah, so I wish that I had taken more professional speaking classes or more communications-based courses. Because as a mathematician, statistician, biostatistician, oftentimes we're knee-deep in the weeds of quantitative analyses or methods-building, but in order for us to translate things you need to be able to have a strong foundation in communications. And so I wish I had taken more of those types of courses, because I've had to pick that up along the way. And I also wish, say, along the lines of communications is more writing courses, because I find tha coming into my faculty position, that was an Achilles for me. Like, that was always a struggle. And so I think writing, professional speaking, any type of communications type of course, I wish I would have taken more of those. Donna LaLonde: Ruby, what about you? Ruby Bayliss: So I can piggyback off of Loni and also agree that I wish I would have taken more writing courses, as well. I definitely struggle with being a very concise writer. I like to justify my justifications and sometimes that's not always necessary. And especially often, like what Lonnie already mentioned, that when you think about math, the numbers explain it for you, but then when you come into more of applied math not only-well, the numbers do explain things for you, but you also have to explain to other people why the numbers explain things. And so that's completely another way of thinking, of how am I going to describe what I'm modeling to the everyday person or how am I going to describe the results that I get to the everyday person and why does it matter to them? Donna LaLonde: So I'll segue to the next question for you, Ruby, and say, so how would you describe the coolest part about your research to to folks who are outside of biostatistics and public health? Ruby Bayliss: So, specifically in my research one thing that I learned was about geographically-weighted logistic regression. And I think that, just in general, being able to model lhow certain variables are related to a particular outcome is really fascinating to me. And so normally in regular regression you're just looking the relationships between variables and your outcome, but then with geographically weighted regression now you're adding another dimension to it. Like, you're adding, like, a particular location-like, how do these variables in a particular location relate to this outcome in the same location. And I think that's really interesting because there's so much variability among-there's just so much spatial variability depending on whether you're looking at county-level stuff, state-level, data. And so that's really fascinating me, just how you're able to model these relationships mathematically. Donna LaLonde: And in your current work are you looking at a particular topic or a particular county or state issue? Ruby Bayliss: Yes, so in context to my research, my outcome is the presence of a water violation in a county and how different neighborhood-level characteristics relate to that outcome. So one of the focuses of my research is, is there a relationship between socioeconomic status and the presence of a water violation? And so I'm looking at a bunch of different socioeconomic status variables along with the demographic makeup of the counties that I'm looking at. [TRANSCRIPT CONTINUES IN REPLY]

[TRANSCRIPT CONTINUES] Donna LaLonde: And just so I understand. A water violation, that would be some kind of contaminant, something found in the water that is not good? Ruby Bayliss: Correct. Yeah, so it's a health-based water violation, and those standards were created by the Safe Drinking Water Act of 1974. And so anything that violates any of those standards counts as a water violation, whether that's contaminants getting in the water, how the water is being treated-because you know we have to treat the water with chemicals-and so are those at safe levels. And of course there's other factors that are involved, but those are the the main ones. Donna LaLonde: Well, that's great. And Loni, I know you're supporting this research and guiding this research, but maybe you may want to add your take on this, but also I know that you have lots of other interesting projects that you've been involved in. So what's the coolest? That's like I'm asking you to pick your favorite child but, well. [laughs] I'll put you on the spot. Loni Tabb: Well, I will say I think the coolest thing about the research that I do in general is the autonomy to research the public health challenges that really mean something to me. And so, Ruby mentioned her work in looking at water violations, when Ruby came into the PhD program, I spoke with her about her interest and what motivates her in the field of biostatistics to research the types of problems that really get her going. And one of our early discussions that came up dealt with the Flint water crisis. And so that's why she is now on this path of looking at county demographics and whether or not that can predict if you see water violations in a given county. And so for me the work that I do, it spans from focusing on say health disparities in-it could be a lot of different health outcomes, but in particular cardiovascular health in this country to all the way to social disparities in cities and whether or not alcohol access promotes more violence. And so there's a wide variety of the types of projects that I work on, but at the end of the day, I think the coolest part is that I'm incorporating space and I'm incorporating time. So where you live, where you work, where you play, where you learn, where you worship, your environment, it has a lot to do with different health outcomes that you might experience. And so I think with space and with health and with time, to be able to see over time what's going on with different health outcomes. And I think that that matters a lot. And so going into my training, I knew that I wanted to look at health-based things, I just didn't know what that actually looked like. And so in my training I focused a lot on mapping and measuring different disparities, and so a lot of the work that I'm doing is still grounded in that, and Ruby-I think it was such a nice match in terms of when she came into the PhD program, that her interests in at least what happened in Flint, Michigan, it's grounded in place-based circumstances. And so I think it's an important lens to look at different public health challenges. So I think that's the coolest part. Donna LaLonde: Could either of you say just a little bit about the tools that you use for your research? Loni Tabb: Yeah. So, for a lot of the place-based work that I do that speaks to the mapping and the measuring of things, I use R. R is a really useful and freely available platform, a statistical software package, that you can do a ton of very-from the the most simple type of statistical analyses to even the more complex. And I have other statistical software packages that I know of and that I use, like SAS, but R is like no other. They don't pay me to say this, I'm not employed by R! But, yeah, that's my primary tool that I take advantage of. Donna LaLonde: Sound like I could surmise that there might be a bit of advice there, learn R. Loni Tabb: Yes, yes. [laugh] Lara Harmon: For anyone listening, they have really good stickers, too. Loni Tabb: They do! Donna LaLonde: They do, they absolutely do. And if you develop a package and you get to name it, then sometimes you get to design the stickers. Loni Tabb: That's right, that's right, yes. Lara Harmon: And the community seems generally very active and interesting Donna LaLonde: So I think I've I've come to the conclusion that we all like stickers. So let me broaden that a little bit and ask both Ruby and Loni what do they like to do when they're not working or teaching or doing biostatistics? And Ruby, I'll start with you. Ruby Bayliss: Okay, no problem. So when it's warm out, I love to go hiking and I just love just being in the outdoors and being away from the city and just enjoying, yeah, more a rural setting. Actually as a kid I was fortunate enough to spend my summers at a lake cabin so I loved being at the lake, and I also loved going to beaches. And originally I'm from Minnesota, so obviously we're pretty landlocked, but we have lots of lakes. And so that's nice, but, definitely, whenever I've experienced the ocean, I've loved it. And so that's definitely one of the things that I was excited about moving to Philly for-well, obviously, besides the PhD program-was being like within like a two-hour drive to the beach. So I'm really looking forward to spending some time outdoors. And then also when it's colder, I actually really enjoy going to movies. Movies are great, and I think one of the things that I really like about movies is it really changes your perspectives. It just really changes your perspectives on different situations that people are put in, and it just is very eye-opening and a lot of thought. And I think even poorly designed movies can evoke different emotions to different audiences, and I think movies are just so relatable and they're just-I don't know, they're just special. Donna LaLonde: You want to give us a recommendation? Anything that you've seen recently? Ruby Bayliss: So unfortunately I haven't gone to see a movie in a while, but... Donna Lalonde: That's a good graduate student response. Lara Harmon: Oh, no, movies are how my sister got through grad school, I think. Ruby Bayliss: No, I usually try to go at least once a month, but I'm trying to think what was the last movie I saw... Well, the last great movie that I saw was actually Hidden Figures. I love that movie. I know it's not in theaters anymore, but it's just such an inspirational movie. It was just so well done. [TRANSCRIPT CONTINUES IN REPLY]

[TRANSCRIPT CONTINUES] Donna LaLonde: That's a great recommendation, yeah. Alright, Loni, when you're not at work or teaching, what is it that you like to do? Loni Tabb: I like to spend a lot of time with my family. I have two little ones, a seven-year-old and a four-year-old, so they keep me very busy. And especially during the summer months, we like to go to the beach and we like to hang out outdoors. I am a city girl at heart, but I like to be outdoors. But that's within certain boundaries. So I love to also go out and eat. I'm a foodie. And so I like to try a lot of different types of cuisines. So I grew up in a Caribbean household, and so I have a lot of bias towards spicy food and Indian food, West Indian food, and so I try to find foods from other cultures that kind of mimic that. And then I am heavily involved in my church.And so I run this ministry at my church called MOPS, it's Moms of Preschoolers, and so it's for moms that have little ones, that they either are members at our church or they're in the community. And we meet up once a month and we do different activities. Sometimes we do volunteer activities, but other times we just simply color. That's what we did last month. So those are some of the things that I like to do when I'm not trying to address some of these different public health challenges that we face in the world. Lara Harmon: I have gotten together with my friends and just colored, too. Loni Tabb: Yes, it's very therapeutic. Very therapeutic. Donna LaLonde: So if a person is visiting Philadelphia, what's the have-to restaurant recommendation, from the foodie? Is that too difficult to choose? Loni Tabb: No, no. I mean, I'm biased, right, so I will say this-if you come to Philadelphia and you are looking for some traditional Philly food you have to get a cheesesteak. And you could get a chicken cheesesteak, a veggie steak, or a regular cheesesteak, and I think the best place to go to get that is... Hm. Which one? Hm-hmm-hmm. I think Delessandra's. That's the best place to go and get steaks in the city. Traditionally speaking, people, when they come into the city, they go to South Street and they go to Geno's or Pat's. Those are very popular touristy steaks. But I don't think that they're like traditional steaks. They're, you know, they're touristy steaks, so if you want the real deal, you have to go to Delessandra's. Lara Harmon: I actually just wrote that down because I know we're going to Philly in a few years for a conference. I'm always like, is there food I can pick up and carry? Donna LaLonde: Yep, that's wonderful. Okay, so our last question for both of you is what question didn't we ask that you would like to answer? So is there something, some area of your research or work or play life, that you would like to share with us that we didn't ask in a question? And Ruby, start with you. Ruby Bayliss: So, I actually had a hard time thinking about this question, because I feel like the questions that you already asked were pretty broad enough to where I could express stuff that I felt without you really directly asking. So I'm sorry, but I'm going have to pass on it. Donna LaLonde: Totally fair. Loni, how about you? Loni Tabb So I, too, struggled with this a bit, but a question that I actually came up with, and you guys have the answer, is how do we best ensure we increase diversity in the biostatistics/statistics field? And well, the reason why I say you guys have the answer is actually through initiatives like this. Ensuring, you know, promoting a field, right, it's almost like our duty to show or at least try to show the representation in that field. So ensuring that women and minorities know that this field actually exists and that it's open to them through initiatives like this, and seeing women and minorities talk about this field, creates a certain picture that the field is actually for everyone and not just a select few. And so I was really happy to hear about this initiative and about the push to kind of get folks out there so that people know that the field is growing, and it has been growing. We still have a ways to go but I think things like this allow folks coming up to know that they belong here. So you guys had the answer. You didn't ask the question, but you have the answer. Donna LaLonde: Oh, well, only with your help, that's for sure. Lara Harmon: Oh, I completely agree. I think that's extremely, extraordinarily important. Donna LaLonde Maybe we should wrap up by coming back to Ruby, and what you described as one of your first experiences. And that is this-to tell folks how they might get involved in a SIBS program, because that acronym might not be familiar. I'm not even sure I know what all the letters stand for. I know what the experience is, but... Lara Harmon: I don't, but I'm a layperson so I'm used to that. Ruby Bayliss: Yeah, sure, I can expand on that. So SIBS stands for Summer Institute in BiostatisticS, and essentially this program was designed for undergraduates, and also recent graduates, to expose them to biostatistics. And so there's different programs at different sites, and each of the different sites have different focuses. I would say what was really great about Emory University was that it was literally right next to the CDC, and so we got to go on field trips to the CDC. and so that was really cool to see what kind of careers you could do at the CDC. And so there were lots of different activities, there was field trips there were panel discussions, there were-we actually learned like R and SAS, and then we also had different professors lecture to us about their research. And the faculty were so great at Emory. And they were completely open and they wanted students to really come and schedule time with them to talk about some individual questions with them, about where to go next. And so I thought that was really such an amazing experience. And so we did all that in like a six-week timeframe, and so it was just unbelievable. And I actually remember talking to one of the organizers for the SIBS program at Emory, and they were telling me about how they were considering not accepting recent grads, and I told them that I think it's important that recent grads are included. Because I was a recent grad when I went to SIBS, and and I can honestly say if I hadn't gone to SIBS, I definitely would not have met Loni at ENAR, because I wouldn't have even known about ENAR at all. And it was actually Renee Moore who connected me with Loni, and Renee Moore was sort of the head organizer of the SIBS program. And so it's a great networking opportunity, as well. And yeah, no, it was just such an invaluable experience, and every time that they send me emails asking me to talk about my experience, I'm more than happy to talk about it, and just talk about how great that program was. And the thing was for me, as well, was I went to a very small liberal arts undergraduate college, St. Catherine University in Saint Paul, Minnesota. And it was great, because the classroom sizes were small, you had a close relationship with your professors. Unfortunately, though, they didn't necessarily supply as many opportunities necessarily.

[TRANSCRIPT CONTINUES] And so when I found out about SIBS, I completely went out on my own to find that opportunity. It wasn't something-it seems like SIBS is definitely becoming more well-known, but it's still not... To a lot of people, they don't even know it exists. And so it's it's just a great opportunity, and it would be great to even get more sites open and more people can attend. Because I think when I went there were only six different sites available. There weren't very many. So I'm hoping that the program can grow, because it's just such a phenomenal program. Loni Tabbs: And I just want to piggyback off of what Ruby had mentioned already about SIBS. Because it's not a program that is at every single university across the country, it is competitive, but the cost associated with even participating is covered for these students, as well. And so not only are they building these relationships and getting a strong foundation, a good chunk of these students move on into PhD programs for biostatistics. And sitting on admissions committees myself for PhD biostat programs and also masters programs, students that go through a SIBS program, they have a certain perspective that other students don't have. And so then their actual application becomes more competitive when they're going into these graduate courses. So I echo what Ruby was saying in terms of I wish there were more of these programs that are funded, and they're funded from NIH, and so hopefully it can continue to grow, so that it can increase awareness for the field. Lara Harmon: Thank you for talking about that. I know afrom my own perspective, when I went to college I did theater, but there's so much you don't know is out there that afterwards it's like, oh, I could have taken advantage of that I could know more about what I'm going to do and with stats that's so important tbecause, stats and math, it's such a an abstract field to everybody who's looking at both of those from outside. So, yeah, I'm really glad to hear that they haven't decided not to take recent grads, that's good. The earlier, the better. I work with our student chapters, and I think the more people can know... The earlier the better they can start looking for opportunities, the better it is. Donna LaLonde: Well, I think that's that. I'd say it's a perfect way to conclude a Mathematics and Statistics Awareness Month conversation to let people be aware of an opportunity. And I'll just add that you're reminding me that, Loni, we may have had the answer, but we can make our answer better by completely describing thes opportunities on the education website of the ASA. So note to self on that, that we should add that to the student section. And of course REUs [Research Experiences for Undergraduates] funded by NSF, which is a bit different experience, but also speaks to your networking and getting involved. So thank you very much!

[TRANSCRIPT CONTINUES FROM DESCRIPTION] Donna LaLonde: So I just have to ask. How many days in advance are planned in that notebook? Eric Laber: So I have long- and short-term plans. So I have a plan for the year, which is very broad, at the beginning of the notebook, and then I have monthly goals and then weekly goals and then I actually now plan-I used to plan each day farther in advance but now I plan each day the morning of and compare it against my week, my broader week plans. So I do it in the morning now because I've realized that having the two little stochastic processes that I count my children makes it really hard to schedule too far in advance, in case somebody gets sick or some other thing happens. But I can usually do it on a daily basis. Lara Harmon: That’s impressive. I’m not the most organized person, so I'm really impressed by that. Alright, so we looked at how you got to where you are, and a rough idea of what a day in your life tends to look like. So looking at that overall, what is the coolest thing in your work or research to you? And possibly to your students. What do they find really cool? Eric Laber: Yeah, I think the things that I find really cool are not always what my students find really cool. Like, so we work on a lot of decision problems-so, how do we use data to make better decisions? And one of the neat projects we're doing now is trying to make better decisions in sports contexts like calling plays in football or rotating pitchers in baseball. And we've been doing this by simulating data with Xboxes or other video game systems. And so we make a bunch of fake data and we train statistical models on the fake data and then we apply it to real data. So for example, we could generate a bunch of video from Madden 2018, where we know where all the players are, the routes that they take, train a computer vision model, and evaluate it on real NFL film and see if we're able to actually do that same kind of identification and tracking with real film, even though we never trained a statistical model using any real film. It turns out that if you do that you can get state-of-the-art accuracy without ever having any real data to train your model. So that's one of the neater projects. We have 17 Xboxes running, generating data, that are being controlled by a server that's calling the plays and recording all the video. So that's something that students, I think, get excited about and I think that's great, too. I also get some of them excited about some of the defense applications that we're working on, where, for example, you have an adversary who has, let's say, nuclear material and they are trying to move it around to a place that you don't want it to be. How do you efficiently coordinate a bunch of search agents in real time to identify and to track down where that adversary is while they're actively trying to avoid you? And so these turned out to be big real-time decision problems. And I like the adversarial nature of it. It has some of the flavor of game theory. So that's something. Donna LaLonde: So, Eric, I just have to ask, because those two contexts are so, well, I guess not maybe completely different, but the idea of applying the decision-making to sports and then the nuclear model they’re… I mean, I know absolutely nothing about football, so how much of a deep dive do you have to do into the domain context to actually start this work? Or do you rely on domain experts to guide you in that direction? Just elaborate a little bit on the domain applications and how you maybe even choose them. Eric Laber: Yeah, so we have a lot of different kinds of decision problems. So the nuclear tracking problem is one, sports decision making’s another. Precision medicine’s another, and now they're trying to design treatments for patients based on their individual characteristics. We also work in anti-human trafficking, so we can identify trafficking victims through text and image data. And we recently got a very small self-driving car that we can control. And so in all these problems, you need domain knowledge to make the thing that you're building, the tools you're building, useful, so you need to know what kinds of things are possible. So if you're coordinating agents in the field that are physically driving trucks around, there's all sorts of constraints associated with that. Like, you know, where are there roads and where aren't there roads and so on, and how frequently can you communicate with people and if you're getting intel how reliable is the intel and how quickly can you assess how reliable the intel is? And in the decision-making game, how much can you rely on historical data to really predict what a team will do in a given situation, and how much input is a coaching staff willing to take from a computer? So in the future they're going to allow-very near future supposedly-allow computers in the booth in college-level football. And so there's this real potential to be running these models in real-time during a game. But then you have to ask what information is going to be most useful. Because the goal is to assist decision-making rather than make it. You don't want a robo-coach, right? You want to give the coach information that could be useful to help them make better decisions recognizing that they're not just going to cede all their decision-making to you. So understanding what's feasible and useful in the context is really important. And so we work with domain experts to understand that. So two of our students are now with professional sports teams. So one is with the LA Dodgers and the other one is with the Philadelphia Eagles. And so working with these organizations helped us understand how these tools might be used so we can make them the most useful. That help? Lara Harmon: Yep. Yeah. I especially find the part about having the computer in the booth interesting, how to balance that. Let's see, so we've done what's the coolest thing about your work and research and then we followed up with Donna’s question… So here we go. Is there a class or classes that you didn't take in college that you wished you had? And I know you've just said that you came to statistics from not statistics so, probably, but… Eric Laber: I always wanted to take piano. I know they offer it, and I just never have done it. Today, being here is going to prompt me into action. I should take piano. Otherwise I would say from a more work point of view that you can never take too much math. So I've never thought, ‘I wish I hadn't taken that math class.’ I’m always thinking I wish I had taken more. I did take a fair number of graduate-level math courses when I was in undergrad, and then also when I was a stats student, but it's really never enough, and I feel like you can never have a deep enough understanding of math. It's always going to help you, no matter what you're doing, even if you're not a mathematician. So I think more math. More computing. I think probably more writing would have been a useful thing for me-might have made my life easier if I had done that. I think I had to learn kind of late in life how to write properly, like when I was a faculty member. So probably should have taken some more lit classes. [TRANSCRIPT CONTINUES IN REPLY]

[TRANSCRIPT CONTINUES] Lara Harmon: I've talked to a lot of folks who are like, communications is really important and we have to follow up and work on that. But that's really interesting. And piano would be a good. And this is a nice segue. So we've established that math classes are extremely important but that piano is also a possible thing, so what do you like to do when you're not working or researching or teaching? Eric Laber: I like to play squash. So that's something I started playing a couple years ago. I highly recommend you play squash, kids! If there's anything you take away from this, it's that you should go play squash. I started playing it a couple years ago and I had never even seen it before. So now I'm totally obsessed. So I do try to play squash when I can, and my dog and I compete in agility, so that's another thing. I got into that when I moved to North Carolina and I was trying to do North Carolina things. So that's something that I've enjoyed and didn't know about until I got here, either. So those are my two. And then I read a lot, so… I read a lot of all sorts of things, sci-fi and nonfiction. Donna LaLonde: So in fair disclosure I've asked this question before, but for the dog lovers out there I have to ask: What's your dog's name and what type of dog is it? Lara Harmon: [laughs] I knew you’d ask about the dog. Eric Laber: His name is Merlin, and he is a mutt, so a mixed dog. And I was trying to see if I had a picture of him in here but… Oh, yeah, here we go. This is a picture of him when he was in the lab. He's sleeping on our bench. Looks a little poodle-y in that picture. So he does come into the lab sometimes and hang out and gets lots of attention. So he likes that. Lara Harmon: So it's squash and agility training. It's a good combination. Okay, so we have the last pre-planned one. So this one leaves it in your court, kind of. What question didn't we ask that you'd like to answer? Eric Laber: I think you didn't ask what advice I would give to a 15-year-old self or just… I think maybe the advice I would like to give to students who are you now starting their undergrad or thinking about starting their undergrad and eventually going to graduate school is to really focus on seeing how good you can become at something. So I think that college and graduate school are a really rare opportunity for you to try to become as good as you possibly can at something. So whether that's math or statistics, which I hope it is, but if it's something else, just see if you can find your own edges and push yourself. Because the obligations of life will eventually sort of consume your time, and so you can really focus on self-improvement during those times and you can find out what you're made of. And I think you can find passion in whatever you pursue as long as you really try to become the best you possibly can. So for me that was statistics and math, but it could be anything. But, I think, don't miss that, because you really won't have another chance, I don't think, in your life, so make the most of it That enough? Is that too generic of advice? Lara Harmon: No, no, not at all. Donna LaLonde: That’s great advice, yeah. So any advice, Eric, on how to begin to do that? It sounds like you knew-although you said in high school, you were the meticulous C student, but how did you know it was math? Or how did you find that that's the edge you wanted to push toward? Eric Laber: Well, I started out as a triple major. I was physics, math, and philosophy. Because I have this problem where I kind of like everything. And then I decided that just in spending time thinking about those three things that I really did want to do math because it felt like it was underneath the surface of all three of those subjects some way, although maybe philosophers would disagree with me. And so then it turned out to be the thing I wanted to learn more about the most and so I decided to really invest my time there. Donna LaLonde: Very cool. Lara Harmon: That is a great and terrible problem to have, being interested in everything. [TRANSCRIPT CONTINUES IN REPLY]

[TRANSCRIPT CONTINUES] Donna LaLonde: Yeah, no, I think it’s wonderful. We have a collection of folks who are interested in everything. What made you switch to UCLA? Any advice on small college versus large school for undergrad? Eric Laber: Yes. So there were two reasons. As I became more interested in math, I kind of exhausted all the math classes that were available at the small school I was at, but also at the time I was-so I guess there’s three reasons. At the time I was a professional magician and LA was a much better place to do that than rural Wisconsin. And I also was a bit sick of the cold. So I grew up in Minnesota, and walking through the snow and the slush, I thought my ancestors should have chosen better where they were going to live. And so I wanted to go and get out of town. So those are the main reasons. Donna LaLonde: Fair enough. Lara Harmon: Alright. Donna, do you have any more questions that we should follow up with? Donna LaLonde: I appreciate very much the insights that Eric’s shared with us, but I'm guessing that there are other entries in that journal that we should let him get on to. Lara Harmon: Yeah, probably so. But, yeah, thank you a great deal. This has gone really well. Thank you very much. [END TRANSCRIPT]

[TRANSCRIPT CONTINUES FROM DESCRIPTION] Stephanie Kovalchik (cont.): So I guess I should say at this point, how does sports fit in with all of this? Because my current role, I'm really a sports statistician but I started out, really, on this track of being a biostatistician and working more within applications in health. And I was quite happily prepared to do that. But I guess I have always had this passion for sport, and I played a number of things as a student in high school. But it was one of those things where I was always better academically, so I knew that wasn't going to be a career as a professional athlete. But it was something that was, I guess, a certified passion. Just watching sport and participating just recreationally was one of the things that I've always done some of that. And I suppose once I was more into stats, it's one of those things that I guess when you start to have this kind of interest in in your field, it sort of starts to color everything that you see around you, even outside of that primary work. So I was sort of starting to see how data and facts were being used in sport, and realizing that for the sport I loved the most, tennis, that there weren't a lot of interesting things really going on compared to the other sports. So it seemed like there were just so many opportunities to do more with the data about the sport. And so I was starting to think about that, and it began just really as a side hobby. So I would spend you know any of my free time looking on the web to find out what data was available about tennis matches and players and starting to think about some of the questions that you could look into with what data was available. And I was sort of pleasantly surprised to find that there was a lot actually out there-that it was just in the public domain. And I think one of the things that was nice at the time is that I was also doing more statistical programming, and it was a way also to use some of those skills that I was developing on the programming side-web scraping and data collection and creating databases and things like that. It was kind of a fun way to use those skills. So I think that was another reason why at a certain time around grad school and sort of the years immediately after that, I think I got particularly obsessed with doing this sort of sports stats. And so I started to do kind of small research projects. And what was kind of amazing is that there was so much that just as an individual with some stats training and a bit of programming in this area where there hadn't been a lot of work, that you just by yourself could do quite a bit that was interesting to other people. And I remember one of the first things that made me realize this was that I had done a little project-looking at it, it was essentially age demographics of tennis players, because at the time-this would be about 10 years ago now-there was a lot of talk around players maybe having to think about retirement as they approach their 30s. So just kind of shocking to us, right, that your career could be over by your early thirties in tennis, but that's the nature of sport. But I realized that there were a lot of very well-known players-like Roger Federer at the time, for example, who was sort of in that group. But their performance would suggest there was really no reason that they should be thinking about retirement. So it seemed like one of these ideas that the tennis media and commentators had that might have been based on an older generation or what was true for previous generations, but that maybe there had been some kind of shift in longevity in the sport. And I was interested if the data would suggest there was actually evidence of that. And so I had done a study looking at about three decades of aging trends among top players and it revealed that there had been an overall shift in in the age of top players that suggested that they were playing to their peak level at later ages. So that was really interesting and I was able to publish that, and then I was asked, actually, by the morning edition of NPR to do an interview about that study. So that made me realize that, ‘oh, I think I'm onto something here,’ because that was just… It seemed like a side project, right, and then all of a sudden it was one of the things I got more interested in than anything else I've ever done. So I think kind of encouraged by that and at that point sort of having a lot of the architecture in place where I had already collected a lot of data and had had the scripts in place to do that, then it became much easier to do more research along those lines. So I was just starting to spend more and more time doing it. Eventually my main outlet for those ideas was through a blog that I created, my On the T blog, which I still maintain. And I think it was through a combination of paper writing for the bigger ideas that were enough to be a part of a full research project and then sort of smaller ideas through the blog and starting to attend conferences like the NESSIS conference, the New England Symposium on Statistics in Sport, which is run by a number of the members of the sports section for the ASA. Conferences like this that gave you a specific setting to talk about statistical work and other people that were doing similar things, I think all of those activities were where I was able to really grow that interest and also make other people aware that I was doing work in that area. And it was actually at one of the NESSIS conferences where I learned about the role that I'm currently at with Tennis Australia, and, interestingly, I hadn't sought out that role in particular. I was not really looking on the market for a job in sports statistics. I mean, unfortunately, I think I assumed that there wouldn't be anything where I could do this work full-time as a job, just because all of the opportunities I had heard about at that point were all with some of the big team sports like baseball, basketball. And those all sounded really fun to me, but then I couldn't imagine not being able to do work in tennis, For some reason I think it's one of those things that you can't really explain, some of the direction that your passions take you or why it is that certain things seem to click, but for some reason it was just in that area where I had the most ideas and it came the most naturally, when I thought of what would be interesting research. So not having ever heard of people being employed in data science and tennis I thought, well, maybe I'm a bit ahead of the curve in that respect. So I wasn't really looking, but luckily enough I did find out about this opportunity that really sounded like a dream position when I heard about it. And it has been something that I'm really glad that I did make the move and decide to shift over to, because it has been a way, yeah, for me to pursue an area of research that I think keeps me the most excited every day. And I think that's what we're kind of all looking for Donna LaLonde: I think you also have an adjunct faculty relationship, as well, so are you currently doing any teaching? Undergraduates or graduate students? Stephanie Kovalchik: Yeah, so I should probably explain the group that I'm with. It has a sort of unique structure. So I'm part of an initiative called the Game Insight Group, and they were formed as a partnership between Tennis Australia which is really, I guess, an industry body, so they're one of the governing bodies in tennis. So they do a number of things to encourage participation and development in tennis and they also run a number of tournaments, including the Australian Open-one of the four Grand Slams, maybe the biggest events that happen in tennis. So Tennis Australia partnered with Victoria University, a local university in Melbourne Australia that has one of the world’s leading departments in sport science. So traditionally the sports sciences fields like biomechanics, physiology, and how those fields impact sport. And so they've started to also develop a bigger emphasis in these statistics, or analytics is kind of a trendy way that they talk about that now. And so this initiative was kind of a natural outgrowth of the interest both of Tennis Australia to improve tennis through science. And then Victoria University is interested in continuing their research and sort of more of the quantitative areas in sport. [TRANSCRIPT CONTINUES IN REPLY BELOW]

[TRANSCRIPT CONTINUES] Stephanie Kovalchik (cont.): And so it's really kind of a 50/50 partnership, and as part of that the members of GIG, as we call it, they have sort of a joint role. So we both have responsibilities with industry and then our responsibilities with Victoria University which are sort of a traditional academic role. So as far as teaching, I do coursework. Usually more guest lectures. There currently isn't an entire course that I run myself, so I will do that. And then I have a number of full day or weekend type of workshops that I’ll usually do usually a few times a year that focus on statistical modeling and prediction in in sport. Donna LaLonde: That's wonderful. So you mentioned that statistics actually came in graduate school, so maybe the answer to this question is statistics, but is there a class or classes that you didn't take in college that you wish you had? Stephanie Kovalchik Yeah, I mean, there's so many things, right? Donna LaLonde: Top choices. Stephanie Kovalchik: I know. I guess something that's immediately in my primary field, stats, that I think I wish I had started earlier and I could see really being important to the work that I do day-to-day right now would be spatial statistics, actually. Because I never had a formal course on spatial stats, but it is something that's really important in sport right now because we're getting a lot of tracking data, the richest juiciest datasets that people are working with at the moment, and they always have a spatial and temporal component, which is like the characteristic of those. So I think that would be something that I think would have been a big help, to have gotten some earlier background with that, I think. Another area as well is with those data, they require usually a lot of pre-processing and it effectively comes down to some signal processing methods where you have to filter-smooth these data, and I think that would have been something, as well, to have a bit more background in. So I think that's probably the most immediate. And then other things in terms of just being a good team member or a manager supervisor that we don't really get much formal instruction on, those. And so I find that I am now and then doing a lot of reading on project management, and in our group we've come around to the sort of, like, agile project management. We've taken a bit more of like a startup philosophy for how we maintain our projects because we do a lot of product development in addition to traditional academic activities like paper writing, and that whole area of managing projects and setting clear objectives, that was all kind of new. so I think it might have been interesting to see what instructors in that area say would be good practices there. So I think that would be interesting as well to have gotten a bit of formal study with. Donna LaLonde: That’s great. So you've kind of talked a little about this, but if you had to pick the coolest thing about your work or research, what would you highlight? Stephanie Kovalchik: Yeah. You think in sport it would be, you know, ‘oh, I get to talk with players’ or something like that, but actually it's honestly when I think about the moments when I get most excited, it's really that point when you have a challenging problem and it's not that obvious what the answer is. And then you have that lightbulb moment where you can see all of the figures and tables coming together of like, oh, how exactly this study would go. I love that. I guess it comes down to the model building stage. And that part of a project is really the most fun to me, where you've done a bit of exploration with the data and now you're starting to kind of understand maybe this measure or outcome that you're interested in, and fitting a model to try to describe that in a mathematical way. That to me is like the most exciting and part of what makes it exciting, though, is to also be able to connect it directly to some way that it's going to have importance for the sport. And that just kind of comes because we always look at questions that we think are relevant to understand something about tennis performance. And so in the background there's always that awareness that, ‘oh, if I can solve this, I know that it's likely to have some positive impacts back to the sport.’ So I think all of those things together make those moments particularly exciting. Donna LaLonde: So, is it still tennis that you like to do when you're not working on research? Lara Harmon (ASA Marketing and Online Community Coordinator): That's a good question. Stephanie Kovalchik: I do like to play socially, but it's just purely for fun. But I do like to be on the court, so I usually once a week will do social doubles, which is a lot of fun and it's very humbling. But it's good, yeah, definitely being active. I love just the outdoors and walking my dog or hiking and things like that, so I've always been a bit of a jock in that respect and still try to get in some activity. I also do quite a bit of dance actually and I like that combination of movement and music. And it feels a bit more of an artistic outlet that sometimes it doesn't always feel like I get a chance for in my day-to-day work. But I actually think that spending that kind of time outside, it's a very specific type of work that can actually help me feel sort of more creative. Because there's a lot of creativity, I think, with the work that we do in stats. Like when you're having to solve problems that maybe nobody's ever thought about or you haven’t heard of people talking about. And I think building models or designing R packages and things, those are quite creative things, even though they might not fit into the traditional sort of acts of creation that we think of. Donna LaLonde: Do you perform for dance or…? Stephanie Kovalchik: Yeah, I have, I have occasionally. Like I'll do teams where we'll do group performances and another routine and then you just all very locally--it's nice to have a very specific goal where it's, there's this performance date that we've all committed to and working together to be ready when that comes around. And I think, yeah, it's a good way to experience it. But I also just enjoy group classes where it's just for fitness, but being with other people that are enjoying the dance and the movement all together… I think it's one of the best ways to experience it, yeah. Lara Harmon: It sounds like a good mix. It's always important to explore all sides of things. [TRANSCRIPT CONTINUES IN REPLY BELOW]

[TRANSCRIPT CONTINUES] Donna LaLonde: So my last formal question is what question didn't I ask that you would like to answer? Stephanie Kovalchik: Oh, that I would like to answer. In terms of thinking of careers, the thing when I think back about what was the key to the direction that I took now… I think it was really just really listening to what your passions were telling you was a good fit for you. And it's one of those intangible things, but I think it's often we think about things like the degrees, the papers, like these very observable things as the goals to go after when judging what makes a great career. But I think that can lose sight of your day-to-day experiences or actual process, and I think it's how you enjoy the process of what you do and what keeps you excited day-to-day that is really going to make a difference for what you yourself feel has been a good choice as a career. So I think that was something I didn't realize as a student for example, but luckily when that time came and I learned about this opportunity to do work in in sport, even though it's an area that very few people can actually get a formal degree in still… And I think in a way, at the time, one of my worries was that, oh, my advisor from graduate school, he might be really disappointed because they’ll all think I've just gone completely a weird direction with all of this training that they did with me. But I think it ultimately came back to thinking, well, this is where I spent all of my time thinking, so that has to mean something. And so just listening to that voice even if it didn't fit in with what might be the role others envisioned for you or you thought of for yourself. So I think that's been something that, thinking back about the big milestones and turning points, that that was a really critical one. Donna LaLonde: That’s great advice, especially for the younger folks who might be listening to this and trying to figure out what their passion is. To know that they should listen to their heart. Lara Harmon: As early on as possible. Donna LaLonde: Well, thank you so much for your time. Unless Lara has questions? Lara Harmon: I think from what you've said, you've kind of covered the biggest question I would have had, which is given the choices you've made in your career, what helps take those big risks? Because like you just said, you took some risks and I'm sure that took thinking and getting right over that edge somehow, jumping for it. So what advice would you give students if they're thinking about something and can't decide whether to go for it or not? Stephanie Kovalchik: Yeah, that's a great way of putting it. And it's interesting as well, to think at the time, the biggest risk was changing essentially my field, going from traditional biostats into sport, making that jump. And at the time I don't even think I was really that aware of the risk. I mean initially I think it was clear, almost, to me that there was really only one choice, which was to definitely move into sport. Just because I had already at that point spent several years where it was just an all-consuming thing this, at the time, I guess people would call it a hobby, because it was something that I did outside of work. But really in terms of where I was spending my time thinking about and what I was really most interested in, it was obvious from that point of view. But I think it was important to have the confidence that I knew what that role would be like. Like what my days would be like and I could sit down and say that these were all of the research questions that I would want to tackle in the first year. So I think that was important, is that what I would be doing was quite clear in my mind. Also being confident that I had the abilities, I had the skills, at that point that I could do those things and pursue them, or for the things that weren't maybe as clear to me exactly how it would work out that I was still confident that I could learn what I needed to to get there. So I think that was important, that I didn't jump in having never really done anything in that area. I felt like I did already have a body of work and time and experience and that even though it had been done fairly independent of my primary work. So I think in a way it made it seem less of a risky endeavor, and I felt that having that background and interest that it really just came down to where I thought I was going to have the most impact. So thinking ahead and it's, like, in five years if I stayed where I was what did I think I would be versus in five years if I took this role what could I be doing? And I think when I had that kind of hypothetical scenario with myself that it was really clear that for me. It was important that if I was going to take a risk in making this move that I would be able to be in a situation where I could help to have some real impact or a big idea. I always put it in terms of if I do anything in my career, I would like to have like at least one great idea. Maybe years from now people look back and say, oh, she did that. I thought that would always be a wonderful thing to be able to have done. And I thought I was really only going to be able to do that if I did take this this change. And so at that point it was sort of a no-brainer for me. Lara Harmon: Thank you! Yeah, I really love that answer. You've gone to such depths to explain things and to be so honest about your career path. That's really wonderful. I think our students will love it. Donna LaLonde: Yeah, absolutely. We are so excited that you were able to participate. Thank you so much for getting up very early. Lara Harmon: Yes! Stephanie Kovalchik: I definitely hope that, yeah, having this experience, that other students who might be thinking about maybe unconventional areas where they can do math and stats or even sport itself, that gives them a better idea.
