I received my B.S. from the Computer Science and Automatic Control Department, Alexandria University, Egypt, and both my MS and PhD from the Department of Computer Science at the University of Pittsburgh. My research interests lie in algorithmic management of massive amounts of data. During my PhD, I interned at Google Research labs from February to July, 2007. Starting February 2008, I joined Yahoo! Inc. as a software engineer in the Yahoo! Open Strategy platform. After almost two years of enjoying product development, I moved to Yahoo! Research in December 2009 as part of the Computational Advertising team.
