I am a first-year CS Ph.D. student at the University of Illinois at Urbana-Champaign in the PL/FM/SE group, advised by Prof. Lingming Zhang. My research interest primarily lies in large language models and software engineering.

I obtained my bachelor’s degrees at Tsinghua University, including one in Software Engineering from the School of Software and one in Business Administration from the School of Economics and Management. I was a research assistant at Software System Security Assurance Group during my undergraduate years, advised by Prof. Yu Jiang.
