My research interests lies in mathematical physics, focussing mostly on general relativity and quantum theory.
Much of my research is centred around twistor theory, a programme originally introduced by Roger Penrose as an approach to the unification of quantum theory and general relativity. Twistor theory now has strong links to string theory and finds wide application to problems in mathematical physics, geometry, nonlinear differential equations, particularly integrable systems. Much of my current work is on ideas arising from Witten's twistor-string theory and applications of twistor theory to scattering amplitudes. Further details of my research interests can be obtained from my publication list (see below for recent articles).
