About Me

I am a Ph.D. candidate in Computer Science at City University of Hong Kong, advised by Prof. Jianping Wang. I have also worked closely with Prof. Heqing Huang and Prof. Yifan Zhang.

My research focuses on AI agent security, fuzzing, and systematic testing and reliability validation of complex software systems. I am particularly interested in uncovering subtle software bugs and exploring how fuzzing techniques can help discover vulnerabilities in emerging AI agent systems.
