My research is in computational photography, with the broad goal of extending what's possible with conventional photography. Before joining Google in August 2011, I was a Research Assistant Professor at TTIC. Before that, I was a postdoctoral fellow at MIT CSAIL, working with Frédo Durand and Bill Freeman. I received my Ph.D. in computer science at the University of Toronto in 2008, under the supervision of Kyros Kutulakos.  [Brief bio] [CV] [Google scholar]
