Research Interests

I am interested in mathematical aspects of quantum field theories, particularly their overlap with twistor theory and string theory. Recently, I have been exploring the rich geometric structures that are present in the scattering amplitudes of four dimensional gauge theory and gravity, especially when reformulated in twistor space.
