About me

I am a quantitative researcher at Citadel Securities in Chicago. I received a Ph.D. from the Department of Statistics at the University of Washington, where I was fortunate to be advised by Zaid Harchaoui and Soumik Pal. Prior to that, I received my B.S. in mathematics and applied mathematics at Tsinghua University.

I am broadly interested in safe and interpretable statistical machine learning with applications to natural language processing. I am also excited about optimal transport and its applications to statistical inference and machine learning.
