About me

I am an NSF postdoctoral fellow at MIT, interested in the interplay between geometric topology, representation theory and combinatorics. Specifically, I study stability phenomena governed by the combinatorics of categorical structures. I got my PhD from The University of Chicago in 2019 under the supervision of Benson Farb.
