About

I work as a cryptographic engineer at Bolt Labs, developing protocols and open-source software that use secure computation to enable financial privacy.

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.

Teaching

I've been a teaching assistant for many courses at the University of Pennsylvania and Tufts University.

I developed coursework for the computer science workshop portion of GEMS 2017, a summer camp for middle-school girls interested in engineering, math, and science.

Other

A variety of research and non-research projects can be found on my Github page, including general notes, teaching materials, and an assortment of half-finished hackathon projects.

My hobbies include fitness in several forms and fabric engineering.
