I am a Principal Research Scientist and the research manager of the MongoDB Cryptography Research group. Before MongoDB’s acquisition, I co-founded and served as Chief Technology Officer at Aroki Systems. Prior to that, I worked as a postdoctoral research associate under the mentorship of Seny Kamara, followed by a role as a visiting scientist in the Computer Science Department at Brown University.

My research interests lie in cryptography and security, with a particular focus on both the theoretical and practical aspects of encrypted search. My recent work has particularly focused on enhancing search functionality, mitigating and formalizing leakage, and designing cryptanalytic attacks to assess practical security guarantees. I am also interested in seeing my work applied in real-world settings. One of my significant contributions is the cryptographic co-design of MongoDB Queryable Encryption.

While affiliated with Brown University, I co-directed the Encrypted Systems Lab. I have also been affiliated as a research visitor or intern with Bell Labs, Microsoft Research, Airbus, Northeastern University and the National University of Singapore.

Apr 01, 2025 Our paper, Bayesian Leakage Analysis: A Framework for Analyzing Leakage in Cryptography will appear at CiC ‘25 (Volume 2, Issue 1). In this work, we propose a Bayesian framework to evaluate cryptographic leakage and its vulnerability to inference attacks.
Dec 01, 2024 Our paper, Concurrent Encrypted Multi-Maps will appear at Asiacrypt ‘24. In this work, we initiate the study of concurrent encrypted data structures and identify several challenges introduced by concurrency in encrypted search.
