About
I am a Research Scientist at Layer 6 AI (US), the TD Bank AI Research. I received my Ph.D. in Computer Science from University at Buffalo, The State University of New York, where I was advised by Prof. Jinhui Xu. I received my M.S. degree in Electrical Engineering from University of Southern California, advised by Prof.
Keith Jenkins,
and my B.Eng. degree from
Guangdong University of Technology, China.
Research Interest
- Large Language Models.
- Trustworthy Machine Learning (Robustness, Adaptation, Privacy, etc.).
