I am a Ph.D. student in the Department of Computer Science and Engineering at The Chinese University of Hong Kong, advised by Prof. Yu Cheng. I received my B.Eng. in Computer Science and Technology (Zhiyuan Honors Program JOHN Class) from Shanghai Jiao Tong University in 2026.

My research interests include large language models, vision-language models, multi-agent systems, and self-evolving agents.
