My primary research interests are in cryptography and security, with particular interest in cryptography in practice, cryptanalysis, privacy, lattices, computational number theory, and coding theory. I am part of the Security Laboratory and the Theory Group at Penn.
Previously, I was a visiting researcher at Microsoft Research New England in Cambridge, MA, and an NSF mathematical sciences postdoctoral fellow in the Department of Computer Science and Engineering at UC San Diego. I have a Ph.D. in computer science from Princeton University and a B.S. in electrical engineering and computer science from UC Berkeley.
