Hamed Hatami

I'm an associate professor at the School of Computer Science and an associate member at the Department of Mathematics and Statistics at McGill University.

I received my PhD from the department of Computer Science, University of Toronto under the supervision of Professors Michael Molloy and Balazs Szegedy. Before joining McGill, I was a Veblen fellow at the Institute for Advanced Studies, and the Department of Mathematics, Princeton University.

My research interests are in Theoretical Computer Science and Pure Mathematics:

  • Communication complexity;
  • Analytic methods in combinatorics and theoretical Computer Science;
  • Fourier analysis of Boolean functions;
  • Additive combinatorics.
