Research

I do research in mathematical and geometric aspects of scattering amplitudes. My current projects at UC Davis focus most on understanding Grassmannian geometries related to non-planar on-shell diagrams in N=4 SYM.

Non-planar on-shell diagrams:


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.
