I am currently a research fellow in the Computer Science Department at National Univeristy of Singapore, where I work with Prof. Gim Hee Lee. Before that, I did my PhD in the Computer Science Department at National Univeristy of Singapore supervised by Prof.Gim Hee Lee, and Master in the Electronic Engneering Department at Beihang University, supervised by Prof. Xia Mao.

Research Field

My research focuses on 3D Computer Vision and Deep Learning. Specifically, I have been working on human and animal pose understanding, implicit neural representation for 3D reconstruction and novel view synthesis. I am also interested in semi-superivsed learning, domain adaptation, few-shot and incremental learning for pose estimation and 3D representation.
