Brief Biography

I received my A.B. from Harvard University in 1996 and my M.S. and Ph.D. degrees from Brown University (Divison of Applied Mathematics) in 1998 and 2002 respectively.  My thesis advisor was Stuart Geman.  I spent the next three years on an NSF Mathematical Sciences Postdoctoral Research Fellowship at the University of Washington (Statistics Dept), UC-Santa Cruz (Computer Science Dept.), and UC-Berkeley (Computer Science/ Statistics Dept.).  I joined the faculty of the Mathematics Department of the American University in Cairo (AUC) in August 2005.
