I am currently a Postdoctoral Fellow at the Harvard Quantum Initiative where I research a wide variety of topics relating to quantum information and quantum computation theory.

I completed both my Ph.D. and B.S. in Physics at the University of Maryland, where I was a Department of Energy Computational Science Graduate Fellow (CSGF), Joint Center for Quantum Information and Computer Science (QuICS) Lanczos Graduate Fellow, and Banneker/Key Scholar.

My work seeks to elucidate the interconnection between the limits of physics, measurement, and computation. In one direction, this means determining what information theory and computer science can tell us about physics and, more practically, showing how they can help us to design better measurement devices and better simulation algorithms. In the other direction, this means deciphering how the constraints imposed by specific physical systems (e.g., symmetries, spatial locality, and noise) impact information-theoretic and computational limits on data processing and extraction.
