About Me

I am a final-year Ph.D. student in the department of Computer Science and Engineering at The Chinese University of Hong Kong. I am fortunate to be advised by Prof. Wei Meng and work with other people in SecLab.

I obtained my B.S. degree in Computer Science and Technology from Tongji University in June 2020, working with Prof. Kai Yang.

<aside> 💡 My research provides (in)formal specifications of undesirable behaviors in various programs, significantly reducing the complexities involved in analyzing these programs for possible security risks. This leads to a broad array of related topics in computer security, programming languages, software engineering, and algorithms & complexity, such as security audit, program analysis, test-input generation, and worst-case complexity of algorithms. I aim to ignite a beacon for vulnerability discovery in the sea of program states and execution paths.
