About Me

I’m a Ph.D. candidate from City University of Hong Kong, supervised by Prof. Rynson W.H. Lau. Prior to that, I received my Bachelor’s degree from Sun Yat-sen University in 2023. My research interests span computer vision and deep learning, with a particular focus on 3D vision, multimodal perception, and generative models.
