Seny Kamara


I am a Distinguished Scientist and Head of Research at MongoDB. I also hold a Visiting Professor appointment in the Department of Computer Science at Brown University. Before its acquisition by MongoDB, I was co-founder and Chief Scientist at Aroki Systems and an Associate Professor at Brown. Prior to that, I was a Research Scientist at Microsoft Research.

My research is in cryptography and is driven by real-world problems from privacy, security and surveillance. I have worked extensively on the design and cryptanalysis of encrypted search algorithms, which are efficient algorithms to search on end-to-end encrypted data. I maintain interests in various aspects of theory and systems, including applied and theoretical cryptography, data structures and algorithms, databases, networking, game theory and technology policy.

At Brown, I co-directed the Encrypted Systems Lab and was affiliated with the CAPS group, the Data Science Initiative, the Center for Human Rights and Humanitarian Studies and the Policy Lab.

Note: Unfortunately, I am not able to take on new PhD students.


May 02, 2024 Take a look at the Re-imagining Cryptography and Privacy (ReCAP) workshop organized by Alishah, Leah and Lucy. I found it to be a really inspiring event.
Aug 01, 2023 After 7 great years at Brown, I joined MongoDB full time.
