About
I am a fifth-year Ph.D. candidate in Cyber Security at Zhejiang University, where I am co-advised by Prof. Shouling Ji, Prof. Xuhong Zhang, and Prof. Peng Cheng. From 2024 to 2025, I was a research associate at the National University of Singapore, working under the supervision of Prof. Abhik Roychoudhury.
Prior to this, I earned my Bachelor's degree in Software Engineering from Zhejiang University.
My research focuses on advancing system and software resilience, with a particular emphasis on operating systems. I am especially interested in the following directions:
- Vulnerability Discovery across operating systems, cloud and web applications.
- Large Language Model applications for operating systems.
- Optimization of Fuzzing Techniques.
