About Me

I am currently a M.S. student in Computer Science and Technology at Peking University. My research interests lie at the intersection of Large Language Models (LLMs) and Software Engineering, particularly in automated program repair, code translation, and automated program understanding.

I have led multiple research projects in collaboration with Shandong University's Research Center for Architecture and Embedded Systems and Shandong University's Smart National Governance Laboratory, under the guidance of Dr. Zhen Yang and Prof. Liguo Fei.

My work has also been fortunate to receive guidance from Prof. Zhi Jin and Prof. Ge Li at the Key Laboratory of High Confidence Software Technologies, Ministry of Education (Peking University). At Peking University, I am now advised by Prof. Dan Hao.

I have published in top-tier venues, including IEEE Transactions on Software Engineering and the ACM SIGSOFT International Symposium on Software Testing and Analysis.
