Biography

I am currently an assistant professor at the University of Hong Kong and a member of Deep Vision Lab. My research encompasses the broad areas of Computer Vision, Deep Learning, and Artificial Intelligence. My objective is to equip machines with open-world capabilities for perceiving, understanding, and reconstructing the visual world, focusing on the following aspects: 1) 3D reconstruction, generation, and visual environment simulation; 2) Open-world, interactive and reliable visual understanding; 3) Efficient training and inference; 4) Applications on open-ended intelligent agents (e.g., autonomous driving, embodied agents). Besides, I am also interested in utilizing AI to advance scientific and medical research (AI for Science and Medicine).

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.

Please email me if you are interested in joining my lab. We have one Postdoc opening in vision for robotics. Please contact me if you are interested in this opportunity.
