Hi! I am currently a fifth-year graduate student at Princeton University, advised by Professor Sanjeev Arora. My research interests broadly include topics in machine learning and algorithms, such as non-convex optimization, representation learning, deep learning, distributed optimization, and convex relaxation (e.g. sum of squares hierarchy). Before coming to U.S., I studied at Andrew Chi-Chih Yao's CS pilot class at Tsinghua University.
I am a research fellow at Simons Institute, Berkeley in this semester until July.
