I am currently a third-year PhD candidate at the City University of Hong Kong, co-supervised by Professor Rynson W.H. Lau and Professor Gerhard Petrus Hancke. Before this, I earned my Bachelor’s degree from the Harbin Institute of Technology.
My research focuses on the intersections of computer vision and computer graphics. I am particularly interested in modeling the physical world using various approaches, including reconstruction, generation, and simulation. I have published papers at the top international conferences with total citations
