I am interested in high dimensional statistics and computational economics.

I am a Ph.D. candidate in the Department of Statistics and Data Science at Yale University. I am very fortunate to be advised by Prof. Zhou Fan. Prior to that, I received my bachelor’s degree from Tsinghua University, where I studied Mathematics and Linguistics.
