about

I am a CS researcher who works in a variety of areas within visual analytics, but focuses on the use of machine learning for human interpretable dimensionality reduction. I also have a strong interest in software engineering and computer science education. My CV is available here.

I completed my PhD in Computer Science at Tufts University where I worked with Professor Remco Chang at the Visual Analytics Lab. I went to undergrad at Oberlin College, where I graduated with a degree in Computer Science and Economics. I was awarded honors in both departments for my two theses: Modeling and High Performance Computing; an MPI Expansion of Nova, and The Effect of District Size on Student Performance, a Story from Illinois.

hobbies

Always down to talk about the the three B's: brewing, board games, or bread. I brew beer from time to time, but am mostly into brewing hard cider at the moment. As far as board games go, social deduction games are my favorite, but I'm also up to hunker down for a game of TI4. I've been trying to perfect my sourdough boule since 2016 and am always looking for tips on the perfect crumb. Below I have some photos from some of the things I enjoy spending time on. As you can tell, photography is not one them.

I've had some number of succulents since around 2013. My first batch of cuttings grew up into quite the collection, but there was unfortunately no room in the car after college. In DC I ended up with a 'succulent staircase' as we had a staircase that lead to a brick wall.. Some of those plants were given away in DC but some are also still with me today!
I find baking to be my favorite 'relaxing' activity. Having time to start some bread on Friday night is one of life's greatest pleasures. I was a pizza cook while at Oberlin, and have tried to keep some of pizza making skills alive over the years. I've had good success using a cast iron skillet on the stove to try to get a better crust before getting the pizza into the oven. I really do miss having access to an industrial stone-lined oven though. Sometimes I have too much fun and try to make sweet things like pie -- it usually doesn't turn out so well.
I haven't had a chance to do any real ceramics in recent years, but it used to take up quite a lot of my time! I hope in my next move to end up closer to a studio. Once I also dug up my own clay and made a pot with it!
