My research interests

I am a director of the Centre for Research in String Theory. My main research interests are centered around string theory, gravity, gauge theories and their interrelations. Exciting advances in these fields have recently come about due to the realisation that certain field theories are dual to certain string theories. This discovery has led to major progress in our understanding of the dynamics of gauge theories at the perturbative and non-perturbative level. In the last years my research has been devoted to exploring theoretical scenarios where the interplay between string and field theory has proved to be particularly fruitful and productive:

  • Study of modern methods for scattering amplitudes in gauge theories and gravity. This includes supersymmetric and non-supersymmetric theories such as pure Yang-Mills and QCD, and theories in various dimensions including ABJM-type Chern-Simons matter theories in d=3 and six-dimensional theories.

  • The novel duality between N=4 super Yang-Mills and twistor string theory, and its applications.

  • The study of the non-perturbative dynamics of supersymmetric gauge theories using exactly calculable anomalies, branes in string theory and dualities.

  • M-theory compactifications on G_2 manifolds and their implications for model building.

  • The AdS/CFT correspondence and its generalisations to non-conformal gauge theories.

My teaching

In the academic year 2012/2013 I will teach Quantum Mechanics B (3rd year BSc, Semester 1) and the MSci/MSc course Advanced Quantum Field Theory.
