Ngai-Man (Man) Cheung is an Associate Professor with Singapore University of Technology and Design (SUTD). He receives his Ph.D. degree in Electrical Engineering from University of Southern California (USC), Los Angeles, CA. His Ph.D. research focused on image and video coding, and the work was supported in part by NASA-JPL. He was a postdoctoral researcher with the Image, Video and Multimedia Systems group at Stanford University, Stanford, CA. He has also held research positions with IBM T. J. Watson Research Center, Hong Kong University of Science and Technology (HKUST), and Mitsubishi Electric Research Labs (MERL).

His research has resulted in 14 U.S. patents granted with several pending. Two of his inventions have been licensed to companies. One of his research results has led to a SUTD spinoff on AI for wound care. His research has also been featured in the National Artificial Intelligence Strategy.

He has received several research recognitions, including recently the Best Paper Finalist at the IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 2019, the Finalist of Super AI Leader (SAIL) Award at the World AI Conference (WAIC) 2019 at Shanghai, China, and the Excellence in Research Award from SUTD.

His research interests are Image and Signal Processing, Computer Vision and AI.
