Biography

I am a researcher of Computer Vision and Robotics at International Digital Economy Academy (IDEA). Previously, I obtained my Ph.D. degree from the department of computer science and engineering, the Chinese University of Hong Kong, supervised by Prof. Qiang Xu. I was a visiting scholar in the Robotics Institute, Carnegie Mellon University.

My research interests include:

1) human-centric visual understanding and perception, like 3d human pose estimation/reconstruction/animation, and human neural rendering;

I'm looking for self-motivated interns at International Digital Economy Academy (IDEA). If you are interested in above topics, please send me your resume by email.
