I am interested in probability theory, mathematical physics, and high-dimensional statistics, with a focus on random matrix theory.

I am currently a postdoc in the group of László Erdős at Institute of Science and Technology Austria (IST Austria).

Before that, I was a postdoc at KTH Royal Institute of Technology, working with Kevin Schnelli.

I obtained my Ph.D. degree in applied mathematics from University of California, Davis in 2018, under the supervision of Alexander Soshnikov.

I received my B.S. degree in applied mathematics from University of Science and Technology of China (USTC) in 2013.
