Background.
I recently completed my Ph.D. at MIT, advised by Shafi Goldwasser. During my Ph.D., I was in the Cryptography and Information Security group within the Theory of Computation group at MIT, and also affiliated with MIT’s Internet Policy Research Initiative and with the Digital Currency Initiative at the MIT Media Lab. I received my B.A. at the University of Cambridge and my S.M. at MIT.

Research interests.
Cryptography, law, technology policy, privacy, security, game theory.
