I am a third-year Ph.D student at Department of Statistics and Data Science, Tsinghua University, very fortunate to be advised by Prof. Pengkun Yang. I obtained my B.S. degree in Mathematics from Department of Mathetical Sciences, Tsinghua University. My research interests are in statistics, probability and theoretical computer science.

Here is my CV (last updated: 2026-02).
