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, etc. I'm particularly interested in the conformal field theories describing these random geometries.

My email is ja3689 at Here's my CV (updated Feb 1 2022).

I am currently teaching Math UN2010 Section 3 (Linear algebra). All course material is available through Courseworks.
