About me

I am currently a third-year PhD student at Pennsylvania State University. I am fortunate to be advised by Dr. Jinyuan Jia. My research focuses on AI Security & Trustworthy ML, recently focusing on LLM robustness and transparency. Previously, I earned double bachelor’s degrees in Mechanical Engineering and Computer Science from RPI, followed by a master’s in Computer Science from Duke University.

Current research focuses

• Transparency of LLM-empowered AI systems for security purposes
• Enhancing the efficiency of optimization-based LLM red-teaming
• Provably secure/robust machine learning systems

Personal

I’m always interested in trying new things. Outside of work, I enjoy playing all kinds of ball sports, hiking, and snowboarding.
