About Me

I received my Ph.D. in Computer Science from Purdue University in 2024, advised by Prof.Dongyan Xu and Prof.Antonio Bianchi. My Ph.D. research applies program analysis techniques, including static source code analysis, binary analysis, symbolic execution, and fuzzing, to secure or reverse engineer software that is specifically related to machine learning and the Internet of things. I received my B.Sc. degree in Computer Science from Sun Yat-sen University in 2018.
