I am a Senior Research Scientist at Google Research. Prior to that I was a Postdoctoral Researcher at Harvard University (Theory of Computation group), where I was gladly advised by Professor Michael Mitzenmacher. I received a Ph.D. in Computer Science from University of Maryland, where I was glad to have Professor Mohammad T. HajiAghayi as my advisor. I finished my undergraduate studies in Computer Engineering at Sharif University of Technology.
