## Research Interests

My research focusses on quantum field theory, string theory and their connections. More specifically, over the past years I have been studying scattering amplitudes in gauge theory and gravity, particularly their secret structures and symmetries. I have been working in this rapidly moving area since its inception in 2004, contributing to a number of key developments which have triggered subsequent important results. These include: the application of MHV diagrams to loop amplitudes in gauge theory, recursion relations for tree-level amplitudes in General Relativity, the correspondence between scattering amplitudes in N=4 super Yang-Mills and lighlike Wilson loops at weak coupling, the proof of dual superconformal covariance of the tree-level S-matrix of N=4 super Yang-Mills.

In the past I worked on non-perturbative effects in supersymmetric theories, particularly instanton effects in Seiberg-Witten theory, on noncommutative theories, and on various aspects of the AdS/CFT correspondence.
