About Me

I am a PhD student working in quantum science and technology. Specifically, I am interested in using modern quantum devices for discoveries in basic science. Quantum simulators (especially analog!) are at an exciting point of being large, well-controlled, and flexible enough to simulate models of interest, in regimes never before possible.

I build tools and work on problems in quantum simulation. Not only does this use ideas from all over physics (quantum information and condensed matter physics, but also quantum optics, quantum field theory and beyond), the type of data generated by quantum devices is intrinsically high-dimensional yet highly structured. This opens the door to using tools from statistics, optimization, signal processing and beyond!

Outside of work, I help run the iQuISE organization (and seminar series), the engageCUA outreach organization, the MIT Lindy Hop Society and the MIT Tango Club!

I am advised by Prof. Soonwon Choi at MIT. Prior to starting my PhD at MIT in Fall 2020, I attended Caltech from 2016-2020, earning degrees in physics and mathematics, where I was mentored by Prof. Olexei (Lesik) Motrunich.
