I am a professor of mathematics at the University of Chicago. I am also a member of the Committee on Computational and Applied Mathematics (CCAM).

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 geometric objects which arise in statistical mechanics. Topics I have worked on include Schramm-Loewner evolution, Liouville quantum gravity, random planar maps, random permutations, random walk in random environment, and various random growth processes.

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 workshop Two-Dimensional Random Geometry which will take place at IMSI in Chicago, July 8-12 2024.

I am an associate editor of Probability and Mathematical Physics.
