I am a third year Ph. D. student in Institute for Computational and Mathematical Engineering at Stanford, advised by Andrea Montanari. Before coming to California, I studied Mathematics at Peking University. My research interest lies broadly in data sciences, say, in the intersection of applied probability, statistics, machine learning, information theory, and computations. Currently, I am interested in random matrices and random graphs, convex and non-convex optimizations, sequential testing and adaptive design.
