Hi! I am currently a fourth-year graduate student at Princeton University, advised by Professor Sanjeev Arora. I am broadly interested in algorithm design and machine learning, including non-convex optimization, deep learning, natural language processing, distributed optimization, convex relaxation (e.g. sum of squares hierarchy), etc. Before coming to U.S, I studied at Andrew Chi-Chih Yao's CS pilot class at Tsinghua University.
