Bio

I am currently a Ph.D. student in the Department of Statistics, University of Wisconsin–Madison. I am fortunate to be advised by Professor Yiqiao Zhong.

Prior to Ph.D., I received my M.S. in Statistics from University of Chicago in 2022, and B.Eng. in Industrial Engineering from Tsinghua University in 2020.
