I am an associate professor at the University of Chicago. I also hold a Clay research fellowship and a junior research fellowship at Trinity college. Prior to coming to Chicago I was a postdoc at the University of Cambridge.

I got my Ph.D from MIT in 2018, advised by Scott Sheffield. Previously, I was an undergraduate student at Northwestern University.

I am interested in probability theory, particularly random curves and surfaces which arise in statistical mechanics. Topics I have worked on include Schramm-Loewner evolution, Liouville quantum gravity, random planar maps, first passage percolation, and Brownian surfaces.

Here is a non-technical summary of my research aimed at an audience with some scientific background, not necessarily in math.

I am a co-organizer of the online seminar Random Geometry and Statistical Physics.
