Siyu Liu

PhD Student in Computer Science

Arizona State University

I am a Computer Science Ph.D student at Arizona State University, specializing in cybersecurity game and program analysis. I am passionate about using game theory to solve real-world problmes in cybersecurity. I am a member of Security Engineering for Future Computing (SEFCOM) lab, where I am advised by with Dr. Tiffany Bao and actively collaborating with Dr. Adam Doupé, Dr. Ruoyu (Fish) Wang, and Dr. Yan Shoshitaishvili.

I am also a member of a qualifying team Shellphish in DARPA/ARPA-H's AIxCC competition ($29.7M prize pool), where I am developing Large Language Model (LLM) applications for automated vulnerability discovery and program repair. You can find our cyber reasoning system Artiphishell submitted to AIxCC final here.
