About
I am a second-year PhD student at Cornell Tech advised by Ari Juels. I graduated from Princeton University with a BSE in Electrical Engineering, where I worked on censorship circumvention systems for my undergraduate thesis, advised by Prateek Mittal. Before starting my PhD I worked for three years as a Trading Engineer at IMC Trading in Chicago.
Research
I'm interested in using cryptography, formal methods and game theory to design systems with security properties that are both provable and interpretable. I'm particularly drawn to tradeoffs between transparency and privacy across domains including blockchain, online communication, and machine learning.
