About Me

I am currently a Research Scientist in Meta Inc.. I received my Ph.D. in Computer Science from Nanyang Technological University, where I was fortunate to be advised by Prof. Tat Jen Cham, Prof. Jianfei Cai, Prof. Junsong Yuan and Prof. Nadia Magnenat Thalmann. Prior to this, I obtained my Bachelor degree from Southeast University.

My research interests include computer vision, especially on vision-based human behavior analysis such as pose estimation, motion synthesis and action recognition. I’m also intersted in graph neural networks and natural language understanding.
