I-Hsun Chen

About me

I am a Ph.D. student in Applied Mathematics at Brown University since Fall 2021, advised by Kavita Ramanan.

My research interests are in probability, with a focus on sparse random graphs, large deviations, interacting particle systems, and their connections to statistical physics and inference.

You can reach me at i-hsun_chen@brown.edu.

I am on the job market for postdoctoral positions starting in Fall 2027.
