I am a research scientist at Akamai Technologies in Cambridge, MA, USA.
Previously I did a postdoc at NEC Labs. My manager at NEC was Vladimir Vapnik. I obtained my Ph.D. from the Technion My thesis advisor was Prof. Ran El-Yaniv.
I also did M.Sc. at the School of Computer Science at Tel-Aviv University, under the supervision of Prof. Amos Fiat.

My major research interests

Statistical and computational machine learning, computational advertising, data mining, information retrieval
