Research

My research focuses on two complementary topics: Integrability in gauge and string theory, and mathematical structures of scattering amplitudes. Both are very active areas of research that hold the promise to substantially improve our understanding of gauge theory at a fundamental level. The newly developed methods radically depart from traditional Lagrangian descriptions, thus admitting unprecedented analytic access to observables in interacting gauge theory at weak, strong, and intermediate couplings.
