Short biography

Alexander WongAlexander Wong is currently the Canada Research Chair in Medical Imaging Systems and an assistant professor in the Department of Systems Design Engineering at the University of Waterloo. He had previously received his B.A.Sc. degree in Computer Engineering from the University of Waterloo, Waterloo, ON, Canada in 2005, his M.A.Sc. degree in Electrical and Computer Engineering from the University of Waterloo, Waterloo, ON, Canada in 2007, and his Ph.D. degree Systems Design Engineering from the University of Waterloo, ON, Canada in 2010. He was also a NSERC postdoctoral research fellow at Sunnybrook Health Sciences Centre.  He has published refereed journal and conference papers, as well as patents, in various fields such as computer vision, graphics, image processing, multimedia systems, and wireless communications. His research interests revolve around image processing, computer vision, pattern recognition, and cognitive radio networks, with a focus on biomedical and remote sensing image processing and analysis such as image registration, image denoising and reconstruction, image super-resolution, image segmentation, tracking, and image and video coding and transmission.  He has received an Outstanding Performance Award, an Engineering Research Excellence Award, an Early Researcher Award from the Ministry of Economic Development and Innovation, two Best Paper Awards by the Canadian Image Processing and Pattern Recognition Society (CIPPRS) (2009 and 2014), and the Alumni Gold Medal.

Research interests

My research interests lie in the field of image processing and computer vision, with a focus on biomedical imagery acquired from different sensing technologies. I am particularly interested in practical applications of efficient probabilistic computer vision and image processing methods to problems in biomedical image processing and analysis.
