Thanks for coming. I am a PhD student at Department of Mathematical Sciences, KAIST, Korea.

In Aug. 2018, I got my M.S. degree in math from KAIST under the supervision of Professor Paul Jung.

My interests are probability and mathematical physics. I’m currently working on higher-order fluctuations of extremal eigenvalues of sparse random matrices.
