Bio

I am a PhD student at The Hong Kong University of Science and Technology, advised by Prof. Yike Guo and Prof. Wenhan Luo. Before that, I received my B.S. in Computer Science and Technology from Sun Yat-Sen University.

Research Interests

World Models, 3D Vision, Video Generation. My long-term goal is to build fully interactive virtual worlds where people can perceive, create, move, and collaborate with the freedom and continuity of a real environment.
