About Me
I am a fourth-year mathematics PhD student at Stanford University. My advisor is
Amir Dembo.
Before coming to Stanford, I was an undergraduate at Seoul National University.
I am interested in probability theory and its applications to combinatorics and mathematical physics. Most of my work has been around large deviations, and some other interests include random graphs, random walks, and random matrices.
Here is my
CV.
