WebbOverview I am an Associate Professor of Computer Science at Brown University and a Distinguished Scientist at MongoDB where I manage the Advanced Cryptography Research Group. Before its acquisition by MongoDB, I was co-founder and Chief Scientist at Aroki Systems. Prior to that, I was a research scientist at Microsoft Research. My research is … WebbWe are interested in the foundations of theoretical cryptography, and in general ways to derive constructions and security guarantees in a modular fashion. One research focus in our group concerns new cryptographic building blocks such as indistinguishability obfuscation, functional encryption, and fully homomorphic encryption.
