Shun-Qing Zhang

I am a theoretical physicist and postdoctoral scholar at Penn State's Institute for Gravitation and the Cosmos, working on mathematical structures in quantum field theory: amplitudes, loop integrals, Wilson loops, correlators, and the geometric ideas that make hard calculations tractable. I am a co-developer of the numerical integration program Trillo.
