I did my undergraduate studies at the Hebrew University, in Jerusalem, Israel. In May 2005 I received my Ph.D. in mathematics from Yale University. It was done under the supervision of Peter Jones. From Fall 2005 to Spring 2009 I was an NSF Postdoc/Hedrick Assistant Professor at the UCLA mathematics department. In fall 2009 I started as an Assistant Professor at the Stony Brook mathematics department. I am supported by the NSF. In the past I was also supported by a fellowship from the Alfred P. Sloan Foundation. (See Funding).
