About Me

I am a PhD student at the The Rachel and Selim Benin School of Computer Science and Engineering at the Hebrew University of Jerusalem. My advisor is Prof. Amnon Shashua. My main research interests are Neural Networks, Graphical Models and Machine Learning in general. I have recieved my B.Sc. degree in Physics, Mathematics and Computer Science from the Hebrew University. Click here for my complete CV.
