I studied computer science at Indian Institute of Technology, Kanpur (B.Tech., 1995) and at University of California, Berkeley (Ph.D., 1999).

After holding positions at DIMACS Center (Rutgers University), AT&T Labs-Research, California Institute of Technology, and Mathematical Sciences Research Institute, Berkeley, I joined University of Waterloo in 2002. I was an associate faculty member at Perimeter Institute for Theoretical Physics during 2003–11.

My research primarily revolves around quantum information and computation, with an emphasis on algorithms, complexity, and communication. I continue to work more broadly on related topics in theoretical computer science.

I am a fellow in the quantum information program of Canadian Institute for Advanced Research (CIFAR), and a member of QuantumWorks, Canada's national research consortium on quantum information science.
