Research

I do research in mathematical and geometric aspects of scattering amplitudes. My master's thesis and following work in Zurich focused on hyperelliptic polylogarithms, a type of special function defined on higher genus surfaces relevant to the integrations carried out in amplitude calculations. I am getting started with research at UC Davis to do with understanding Grassmannian geometries related to non-planar diagrams in N=4 SYM.

Non-planar on-shell diagrams:
