I work in Cryptography and the foundations of Security, and more broadly in Theoretical Computer Science. My primary interests lie in the theoretical foundations of
protocol design: cryptographic proof systems, non-malleable cryptography and multi-party computation.
Before joining UIUC, I was a Postdoctoral Researcher at Microsoft Research New England, working primarily with Yael Kalai.
Before that, I obtained my PhD from UCLA under the fantastic supervision of Amit Sahai and Rafail Ostrovsky.
You can find my CV here.
I am looking for motivated students and postdocs! Please send me an email if you are interested in working with me.
