Intro

I received my PhD in Tsinghua University on July 2018. Currently I am working at VMware as a Member of Technical Staff. My research focuses on constraint solving, static analysis and program repair. I am working on building a static analysis platform to automatically detect and fix complicated vulnerabilites in real-world software systems. I am interested in how static analysis techniques unleash the software productivity.
