Pappalardo Fellow in Physics at MIT

I am a Pappalardo Fellow at MIT, in the Center for Theoretical Physics.

I study the physics of quantum field theories. The goal is to understand behaviors like the confinement of quarks in quantum chromodynamics using non-perturbative methods. I primarily work on applying Hamiltonian lattice gauge theory to low-dimensional gauge theories, and applying the conformal bootstrap to superconformal field theories. See my publications for more details. I am also involved in outreach efforts, including the National Science Bowl.

Previously, my notes “Undergraduate Physics in a Hurry” were hosted here. These notes have become a book with Princeton Press, co-authored with Andy Leifer and now titled Undergraduate Physics: Four Years in One.
