I am currently a Ph.D. student in CS department at University of Washington, advised by Sewoong Oh. Previously, I received my M.S. and B.Eng. in Electrical Engineering from University of Illinois at Urbana-Champaign and Shanghai Jiao Tong University，respectively. My research has been supported by the 2021 Qualcomm innovation fellowship.
My research interests include deep learning, robust statistics, and differential privacy.
