[CV] [Resume] [Google Scholar] [LinkedIn]

I am a Ph.D. candidate at University of British Columbia, advised by Alla Sheffer. My research focuses on line drawing processing, generation of stylized images from digital models, and building tools that help drawing and creation in general. I received my M.S. at Carnegie Mellon University and my B.Eng. at Beihang University in China. I have previously interned at Adobe Research and Disney Research.
