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.

I spent Summer 2013 with Dirk Balfanz and the security engineering team doing research on the Security Key at Google. I spent Summer 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 in 2009.

Service

I have served or am serving on the program committees for the following conferences: IEEE S&P (Oakland) 2019, PETS 2019, CRYPTO 2018, and PETS 2018.

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.
