About Me

I am a second-year graduate student in Computer Science at Peking University, advised by Prof. Yuexian Zou. Previously, I earned a B.A. in Environmental Engineering from Sun Yat-sen University.

My research focuses on enhancing the general capabilities of Vision-Language Models (VLMs) and developing trustworthy AI agents.
