Principal Researcher
About
I am a Principal Researcher in the Cryptography group at Microsoft Research, Redmond. My primary research interests include key transparency, end-to-end encrypted communication, key management, decentralized identity systems, secure computation and authenticated data structures. I have also worked a bit on privacy leakage in systems deploying ML models. Before joining MSR, I graduated from Brown University (opens in new tab) in 2018. During my Ph.D. I was awarded the Microsoft Research Dissertation Grant 2017-2018 (opens in new tab), and the Paris C. Kanellakis Fellowship (opens in new tab).
