I am a visiting scientist at Facebook AI Research and incoming assistant professor at Stanford University. My research mission is to understand and develop efficient machine learning (and deep learning) algorithms. I received my Ph.D. from the Computer Science Department at Princeton University. As an undergrad, I studied at Andrew Chi-Chih Yao’s CS pilot class at Tsinghua University.


Non-convex optimization, deep learning and its theory, reinforcement learning, representation learning, distributed optimization, convex relaxation, and high-dimensional statistics.
