Research

My research interests lie in computer vision and in medical imaging. I have worked on a variety of problems in early vision, including motion and stereo; many of these problems can be solved very accurately using algorithms based on graph cuts, which was given the Test of Time award at ICCV 2011 and the Koenderink prize at ECCV 2012. I served as a Program Chair for CVPR 2007 (the primary North American vision conference), and for the International Workshop on Computer Vision 2008, 2010 and 2012 (a small workshop for senior vision researchers), and was a General Chair for CVPR 2013. I was the Editor-in-Chief of the IEEE Transactions on Pattern Analysis and Machine Intelligence from 2009 through 2012, and I now chair the PAMI-TC, which runs the main vision conferences. I also am the president of the Computer Vision Foundation, a non-profit which now co-sponsors CVPR and ICCV with the IEEE Computer Society.

Starting in the fall of 2013 I am at CornellNYC Tech with a joint appointment in Weill Cornell Radiology. My medical work has focused on the problem of MR image reconstruction, as well as on workflow issues.

Students

I am particularly proud of two students who have returned to Cornell: Ashish Raj, who has a faculty position at Cornell Radiology, and Greg Pass who is the Chief Entrepreneurial Officer at Cornell NYC Tech. My current PhD students are Alex Fix and Chen Wang (in CS) and Akshay Bhat (in IS). Alumni include Yuri Boykov (postdoc), Jing Huang, Olga Veksler, Vera Kettnaker, Junhwan Kim, Vladimir Kolmogorov, Gurmeet Singh and Jie Zhu (PhD students) and Devin Kennedy, Chris Danis, Brian Rogan, Brian Cody, Justin Miller and Justin Voskuhl (undergraduates).

Teaching

I developed a new course, originally called CS100R, that uses camera-controlled robots to introduce basic concepts in computer science. I typically teach graduate computer vision , or advanced undergraduate programming, . In the past I have taught CS212, an honors-level freshman introduction to CS.
