Dr. Oded Regev received his B.Sc. in Physics and Mathematics from the Hebrew University in Jerusalem, Israel and went on to receive his Physics PhD, in 1981, from the Tel Aviv University, Israel. He conducted his post-doctoral research at the University of Florida after which he held a lecturer position at the Physics Faculty of the Technion in Haifa, Israel. He advanced to Full Professor in 1996 and retired in 2006 and received the status of Professor Emeritus.  He spent his sabbaticals in England (Leicester University), France (Grenoble University and later in the Paris Institute d'Astrophysique). His two year (1987-1989) leave of absence was devoted to research and teaching at Columbia University. He lives now in New York, doing some collaborative research but focusing mainly on writing physics text books and recently fiction in the form of short stories. regev@physics.technion.ac.il  www.regevale.com Dr. Orkan M.
