I am currently a Member of Technical Staff at a startup working on AI for Biology, and also a PhD student at Princeton advised by Ryan P. Adams. I am particularly interested in machine learning and its applications to problems in science and engineering. In Summer 2023 I worked at at NVIDIA with the Totonto AI Lab, specifically in the intersection of numerical simulation and machine learning, and in Summer 2022 I interned at Google Brain Princeton with Elad Hazan. Previously, I was a Google AI Resident, working in the intersection of applied information theory and machine learning.

I did my BS and MEng in Computer Science at MIT, where I worked with Carl Vondrick and Antonio Torralba.

Open Source Code:

For my PhD research, I developed Varmint, a JAX-based nonlinear solid mechanics simulator that is fully differentiable and can easily interact with neural networks.
