 Avishay Tal
Hi, I'm Avishay, an Assistant Professor at the Department of Electrical Engineering and Computer Sciences at UC Berkeley. I am proud to be part of Berkeley's Theory Group.
In 2015, I received my Ph.D. from the Weizmann Institute of Science, under the guidance of Ran Raz. Prior to that, I was an MSc student at the Technion under the guidance of Amir Shpilka. I feel very fortunate to have had both Amir and Ran as my mentors. I held postdoctoral appointments at the Institute for Advanced Study (hosted by Avi Wigderson), Simons Institute (as part of the Lower Bounds in Computational Complexity program), and Stanford University (hosted by Omer Reingold). Main Research Interests:
