About Me

Welcome to my website! I am a final-year Ph.D. student in Electrical and Computer Engineering at Syracuse University, supervised by Dr. Yuzhe (Richard) Tang. My research interests are in systems and program security, with a current focus on cryptocurrency and decentralized finance security.

I was a Security Research Intern at CertiK in Spring 2026. I received my Bachelor's degree from Harbin Institute of Technology and my Master's degree from Syracuse University in 2020.

Research Interests

  • Vulnerability discovery (by program analysis + AI)

  • Security measurement

  • Blockchain systems security

  • Deception schemes and scams
