Ph.D. student in physics at Princeton

I am an NSF Graduate Research Fellow studying high-energy theory at Princeton, advised by Silviu Pufu.

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 at Princeton and with the National Science Bowl.

You might be looking for:

  • My tool for drawing Feynman diagrams and generating tikz-feynman code
  • Undergraduate Physics in a Hurry, a rapid review of undergraduate physics with 100+ solved problems from Princeton’s preliminary exam in physics. I am in the process of turning this into a book with Princeton Press, co-authored with Andy Leifer. When that is complete, the draft version will no longer be available here.
