I am an NSF Postdoctoral Fellow at the Courant Institute sponsored by Scott Armstrong. I began my fellowship at Cornell University sponsored by Lionel Levine. I received my PhD at the University of Chicago under the supervision of Charles K. Smart in June 2022. Previously, I received a B.S. in mathematics and an M.S. in statistics from Stanford University.

I am interested in probability and partial differential equations. Some topics I have worked on include quantitative stochastic homogenization, the Abelian sandpile, and Liouville quantum gravity.
