About Me

I am a fifth year PhD student in Mathematics and an NSF Graduate Research Fellow at the University of Pennsylvania. I am on the job market this fall. I am co-advised by Mona Merling and Kirsten Wickelgren. I am interested in enumerative geometry and algebraic topology, particularly $\textbf{A}^1$-homotopy theory and equivariant homotopy theory. My CV is here.

I co-founded the Penn chapter of the Directed Reading Program with Mona Merling, which I now co-organize with Marielle Ong. We were recently featured in an article in Omnia.
