I am a computer scientist broadly interested in cryptography and security. At Google, I work in the security research team with Úlfar Erlingsson on differential privacy (RAPPOR) and applied crypto.

I graduated in 2014 with a Ph.D. from the Department of Computer Science at Stanford University. My Ph.D. advisor was Prof. Dan Boneh. My research focused on modeling and building secure deterministic and searchable encryption schemes. I also worked on building lattice-based cryptographic primitives, among other topics in cryptography.

I spent the summer of 2013 with Dirk Balfanz and the security engineering team doing research on the Security Key at Google. I spent the summer of 2012 at Microsoft Research (Silicon Valley) working with Gil Segev and Ilya Mironov.

Earlier, I graduated from the Computer Science and Engineering Department at IIT Madras with a Bachelors of Technology in Computer Science with a minor in Physics in July 2009.
