I am a PhD student in mathematics at the University of Michigan. My advisor is Andrew Snowden.

I'm interested in questions on the interface between topology, combinatorics, and representation theory, which come out of the area of representation stability. I like to think about configuration spaces, moduli spaces of curves, subspace arrangements, representations of FI-like categories and twisted commutative algebras, Koszul duality, and representations of posets.
