About
Overview
I am a theoretical physicist interested in strongly coupled quantum field theories and scattering amplitudes. I am a leading figure of the numerical S-matrix Bootstrap program. My work focuses on optimisation-driven bootstrap techniques to obtain rigorous, non-perturbative constraints in quantum gravity, effective field theories, and quantum chromodynamics (QCD). For a general-audience introduction to some of these ideas, you might enjoy this article in Quanta Magazine.
