BIOGRAPHY

I am an associate professor in the Electrical Engineering Department of Stanford University and a member of ISL. Before joining Stanford, I was a postdoctoral researcher with the Algorithmic Research on Networked Information Group at EPFL, Switzerland. I received my PhD degree in October, 2009 from the Information Processing Group at the same university. I received my B.Sc. degrees in electrical engineering and physics from Middle East Technical University, Turkey, in 2001 and the M.Sc. degree in electrical engineering from the same university in 2004. From 2001 to 2004, I worked as a hardware design engineer for the Defense Industries Research and Development Institute in Turkey.
