  • B.Tech., Indian Institute of Technology, 2006

I am broadly interested in privacy-preserving and secure systems. My current focus areas include projects in:

Security and Machine Learning

Privacy and Machine Learning

Privacy, Security, and Networked Systems 

My research draws on techniques from data science, network science, distributed systems, and applied cryptography. My work has influenced the design of widely-used systems such as the Tor network for anonymous communication, and the Let's Encrypt Certificate Authority. I am also an associated faculty of the Computer Science Department, and the Center for Information Technology and Policy (CITP).
