About Me

I am a third-year Ph.D. student at University of Macau, working with Prof. Zhedong Zheng. Previously, I obtained a bachelor’s degree in computer science from Fudan University in 2021.

I am interested in computer vision and related topics. I believe the ultimate goal of computer vision is to make machines see like humans. Currently, my research focuses on enhancing the reasoning and tool-use capabilities of multimodal agents through reinforcement learning.
