      I'm currently a Post-Doctoral Fellow worked with Professor Zhou Wang, in the Department of Electrical and Computer Engneering, University of Waterloo. I got my Ph.D. degree in University of Waterloo, Ontario, Canada, and obtained both of my Master and Bachelor degree in Xidian University, Xi'An, Shannxi, China.

      My research interests include signal processing, image & video processing (coding, denoising, analysis, and representation). My major research direction is image & video quality assessment and their applications.
