🌟 About Me

I am currently an associate professor at the Beijing Key Laboratory of Intelligent Software Engineering, Institute of Software Chinese Academy of Sciences (ISCAS). Prior to joining ISCAS, I spent two years as a Postdoctoral Associate with the SEKE Lab in the Key Laboratory of High Confidence Software Technologies, Ministry of Education at Peking University (PKU), co-hosted by Prof. Zhi Jin and Prof. Ge Li. I received my Ph.D. from the School of Computer Science (National Pilot Software Engineering School) at Beijing University of Posts and Telecommunications (BUPT), under the supervision of Prof. Yunzhan Gong.

I work on the intersection of Software Engineering, Artificial Intelligence, and System Software. I aim to build intelligent LLM-based agent systems that automatically assure the quality and reliability of basic software. To achieve this, my current projects explore the following directions:

📢 I’m actively looking for highly self-motivated undergraduate students and new graduates to join us. If my research catches your eye, just shoot me your CV directly!
