Research Interests

I am interested in Quantum Field Theory, String Theory and Quantum Gravity, especially in mathematical and physical aspects of scattering amplitudes in these theories. Recently I have been working on the all-loop planar S-matrix of maximally supersymmetric Yang-Mills theory, and reformulations of scattering amplitudes for massless particles in general Quantum Field Theories.
