Since February 2008, I am an Assistant Professor at TTI-Chicago, a philanthropically endowed
academic computer science institute located on the University of Chicago campus.
I also hold a part-time faculty appointment at the University of Chicago Department of Computer Science.
We at TTI-Chicago continue to admit students to our PhD program. Please contact me for details.
Prior to coming to TTI-Chicago, I was a post-doctoral researcher at the Department of Computer Science of Brown University where I worked with Michael Black. I received my PhD degree at MIT where I worked at CSAIL with Trevor Darrell on computer vision and machine learning. My thesis topic was Learning Task-Specific Similarity.
Before coming to MIT, I was a graduate student in the Computer Science Department of the Technion, Israel Institute of Technology in Haifa, Israel, where I got my MSc thesis under the advisement of Ran El-Yaniv and Yoram Baram. I got my undergraduate degree in Math and CS from Hebrew University in Jerusalem, Israel.
