I am currently a computer vision lead at ByteDance/TikTok, Singapore and also holding an appointment as an adjunct assistant professor at the National University of Singapore. Before that, I was a research fellow at the University of Oxford, and a member of Torr Vision Group (TVG) working with Prof. Philip H.S. Torr. I regularly serve as an Area Chair for top-tier artificial intelligence conferences including CVPR, ICCV, ECCV, NeurIPS, ICML and ACM MM, and serve/have served as an Associate Editor of Pattern Recognition and Guest Editors of IEEE Transactions on Pattern Analysis and Machine Intelligence.

[Hiring!] Actively recruit engineering managers, scientists, interns in China, Singapore, and the US. Feel free to contact me!
