Chen Li

I am a Senior Research Scientist in IHPC, A*STAR, working with Dr. Basura. Previously I was a research fellow in the Computer Science Department at NUS, where I worked with Prof. Gim Hee Lee. Before that, I did my PhD at the same department supervised by Prof.Gim Hee Lee, and Master in the Electronic Engneering Department at Beihang University, supervised by Prof. Xia Mao.

I am looking for self-motivated PhD students, visiting students and interns. Please drop me an email if you are interested. Scholarships are available at link. I am also open to collaboration.

Research Field

My research focuses on 3D Computer Vision and Deep Learning. Specifically, I have been working on 3D human/animal pose modeling and motion reasoning, 3D general scene modeling and understanding, human-scene interaction modeling.
