Biography

I am currently a postdoctoral researcher in University of Oxford, supervised by Prof. Philip H. S. Torr . Prior to that, I obtained my Ph.D. degree in Computer Science and Engineering Department, The Chinese University of Hong Kong (CUHK), supervised by Prof. Jiaya Jia in 2018. Before that, I got the B.Eng. degree in Electronic Science and Technology at Shanghai Jiao Tong University (SJTU) supervised by Prof. Ya Zhang in 2014.

My research interests include artificial intelligence, computer vision, robotics, deep learning, and medical image analysis. Specifically, I study "how intelligent systems can perceive, understand and reconstruct the visual world".

I will join HKU as an assistant professor at the Department of Electrical and Electronic Engineering starting from February 2020. Please do not hesitate to drop me an email if you are interested in joining my lab.
