I like using 2-category theory to study the interplay between categorical algebra and combinatorics. This takes me into both pure and applied category theory. See my research page for more specifics. If you are curious how exactly I got into this stuff, you can read this blog post.
I’m also interested in biology/ecology, physics, computer science/programming, lingustics, sociology, etc. Beyond academia, I’m super interested in music, coffee, D&D, and vegetarian cooking.
