About

I am a second year PhD student working with Professor Yevgeniy Dodis in the Cryptography Lab at NYU. We work on projects that apply rigorous formal analysis to real-world protocols. We have focused on Secure Group Messaging and Video Chat — specifically efficient group key agreement protocols with robust security properties and associated communication complexity lower bounds — and private outsourced storage protocols — specifically a tight computational complexity lower bound for a decades-old forward secret storage primitive and a combination of the primitive with oblivious RAM that adds (almost) no additional overhead.

I previously obtained a BS in Computer Science from Columbia University, where I worked with Professor Allison Bishop. We worked on projects related to Lattice-Based Cryptography and its connections (or lack thereof) with Group-Based Cryptography.
