Hi! I'm a Junior Fellow at the Simons Society of Fellows, working at Columbia University.

I received my Ph.D. in Mathematics from MIT in 2022, advised by Scott Sheffield. I previously completed a B.S. in Mathematics and M.S. in Statistics at Stanford.

I'm interested in probability theory, especially random conformal geometry: Schramm-Loewner evolution, conformal loop ensembles, Liouville quantum gravity, random planar maps, conformal field theories describing these random geometries.
