Outside of work, I read books, work out (lifting, running, and bouldering), and go outside. I also enjoy occasional craft projects and this website.
I received my PhD in 2021 from the Distributed Systems Lab at the University of Pennsylvania, where I was advised by Nadia Heninger. My research focused on secure multi-party computation (MPC) as it transitions from a theoretical academic construct into a practical tool for privacy preserving data computations. I spent summer 2020 at Microsoft Research, working with Hao Chen at the Cryptography and Privacy Research group and summer 2019 at Boston University, working with SAIL on JIFF, a framework for MPC.

I created a software repository with build environments for every tool we surveyed, plus some new ones.
