I am a software engineer at Google. Previously, I was a Security Researcher at Baidu X-Lab. I finished my Ph.D. at the College of Information Sciences and Technology, The Pennsylvania State University, in 2018. I received my master's degree from University of Waterloo and my bachelor's degree from Peking University. My research interest subsumes dependable software engineering, program analysis, formal methods, trusted execution environments, and software obfuscation. Recently I started to work on web security, mostly to fight XSS. I am actively exploring multiple security research domains. My work has been regularly recognized by both the industry and academia.
