This page is no longer maintained. Effective January 2021, I will be moving to the University of Delaware. Please visit my new page.

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. Click here to check if I have an immediate M.Sc./Ph.D. opening. Undergraduate students click here.

Please submit to a special issue of Algorithms on Multilevel Methods

We are soliciting high-quality original research papers (and significant work-in-progress papers) describing any aspects of multilevel algorithmic approaches, as well as the design and implementation of solutions and systems in which the multilevel approach plays one of the central roles.
