Bio

I am a computer scientist broadly interested in cryptography, security, and machine learning. At Google, I work in the security and privacy research team under Google Brain with Úlfar Erlingsson on differential privacy (RAPPOR), applied crypto (incl. post-quantum crypto), and topics at the intersection of security and machine learning.

I am also part of the FrodoKEM team that designed and submitted the Frodo Key Encapsulation Mechanism to the NIST post-quantum crypto candidates competition.

I received my Ph.D. from the Department of Computer Science at Stanford University advised by Prof. Dan Boneh. My thesis 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.

During my Ph.D., I spent summers with Dirk Balfanz and the security engineering team doing research on the Security Key at Google, and 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.

In the past, I have reviewed papers for the following conferences: CRYPTO, EUROCRYPT, IEEE S&P (Oakland), Usenix Security, PKC, TCC, PODS, ICALP, Financial Crypto, and ICISC.

Teaching

I helped my advisor with this excellent online course! in the Winter of 2012.
I was a Course Assistant (CA) for CS255: Introduction to Cryptography in Winter 2012 and 2011.

Personal

My sister Aditi Raghunathan.

A short write-up on the Gödel prize-winning Toda's theorem—one of my favorite results in complexity theory—as a project report for Prof. Luca Trevisan's CS254.
