I received my Ph.D. from the Weizmann Institute of Science (Israel) under supervision of Achi Brandt and Dorit Ron, in 2008. In Fall 2012, I joined the School of Computing at Clemson University. I am also a Faculty Scholar of the Clemson University School of Health Research. Before that I was at Argonne National Laboratory. My undegraduate school is Ben-Gurion University of the Negev.

I am actively looking for highly motivated students to work with (both undergraduate and graduate). You are always welcome to stop by my office to chat.
