About Me

I received my Ph.D. at the University of Southern California where I was supervised by Prof. Muhao Chen. My research interest lies in natural language processing and machine learning. In particular, I’m interested in (1) developing robust and generalizable knowledge acquisition models, (2) developing techniques to add or remove knowledge from LLMs, and (3) enhancing the trustworthy of LLMs.
