Biography
Hi! I am a CS Ph.D. student at the Department of EECS, UC Berkeley, where I am fortunately advised by Prof. David Wagner. I am part of the Wagner Lab, Security Group, and Berkeley AI Research. I got my M.Eng. and B.Eng. (Summa Cum Laude) from Shanghai Jiao Tong University supervised by Prof. Xiaolin Huang. I also had a great time visiting UW, NEU, UCSC, and interning at Tencent, Meta AI FAIR. I was the chief director of three 1K-spectator concerts. See more experiences/publications on my CV.
My research focuses on AI security in real-world applications. I am currently interested in behavior control of large language models for trustworthiness, e.g., prompt injection defense (arXiv’24, arXiv’23) and rule-following (arXiv’23). I have also worked on poison (ICLR’23, ICLR’23) & query (TAI’23) & transfer (TPAMI’22, PR’22, ICASSP’23) attacks and black-box (NeurIPS’22, TIST’23) & white-box (CVPR’22, CVPRW’23) defenses on computer vision models. Feel free to drop me an email if you would like to chat on research and/or PhD application (previous SoP).
