My research focuses on particle physics as well as properties of holographic principle, black holes, and quantum field theory. This encompasses the study of scattering processes such as collisions of quarks and gluons in colliders. These processes are marked by a simplicity of mathematical structure that has puzzled physicists for several decades. Progresses in the computation of amplitudes in flat spacetime can also be extended to curved spacetime.
