About

I am a Ph.D. student at Princeton University, advised by Prof. Danqi Chen. I received an M.S. in Computer Science from University of Illinois at Urbana-Champaign in 2019, advised by Prof. Tao Xie, and a B.S. in Computer Science from Peking University in 2017.

I am interested in natural language processing and machine learning. My long-term goal is to build efficient and robust systems that can understand human language.
