About Me

I am a PhD student at the Data Science and Analytics Thrust, Information Hub, The Hong Kong University of Science and Technology (Guangzhou), where I began my PhD studies in February 2025. I am advised by Prof. Zishuo Ding and Prof. Zhenhao Li. I received my B.E. degree from Beijing University of Posts and Telecommunications (BUPT) in 2024.

My research focuses on coding agents, with two primary directions: enhancing their debugging capabilities and improving their ability to optimize code.

Beyond Research

Beyond research, I enjoy landscape and portrait photography; you can find a selection of my work here. I am also interested in anime, comics, and games (ACG), with a particular fondness for the Touhou Project and all-girl band series. When it comes to football, I am a devoted supporter of FC Bayern Munich.
