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.
Teaching and pedagogical matters:
