I received my B.Sc. in Mathematics and Computer Science from Tel Aviv University in 1986 and Ph.D. in Computer Science from the Weizmann Institute of Science in 1991. I later was a postdoctoral fellow at the Massachusetts Institute of Technology in the Department of Brain and Cognitive Science and the Artificial Intelligence Laboratory. Since 1992 I have been affiliated with the Weizmann Institute of Science in the Department of Computer Science and Applied Mathematics where I am currently holding the position of Professor and, starting 2019, serve as Dean of Mathematics and Computer Science. At the Weizmann Institute I served as the Chair of the Board of Studies for the Faculty of Mathematics and Computer Science between 2004 and 2006, and as Head of the Department of Computer Science and Applied Mathematics (2007, 2016-2019). I took visiting positions at NEC Research Institute in Princeton, New Jersey (1999-2000), Toyota Technological Institute at Chicago and the University of Chicago (2007-2009), the Janelia Farm Campus of the Howard Hughes Medical Institute (2009-2011), and the University of Maryland (2017-2018). I served as Associate Editor for the IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI, 2002-2006) and as Program Co-Chair for the IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2014, and Area Chair for CVPR, as well as for the IEEE Int. Conference on Computer Vision (ICCV) and the European Conference on Computer Vision (ECCV).
My research has focused on computer vision, especially in the areas of image segmentation, shape reconstruction, and object recognition. In particular, I developed methods for analyzing the effect of lighting on images, as well as multiscale algorithms for segmentation and edge detection and region-based pose estimation techniques. In addition, I am interested in the analysis and application of machine learning techniques. My work deals with the design of algorithms, analysis, and implications to human vision.
