About

I am a fifth year Computer Science PhD student at Cornell University. I am based at the Cornell Tech campus in NYC and advised by Tom Ristenpart. My research interests lie in security and applied cryptography. In particular, I am interested in building end-to-end encrypted systems with strong security and privacy guarantees, while mitigating abuse and preserving user agency. I use he/him pronouns.
