String Theory, QCD and Black Holes

I intend to use string theory to understand gauge theories in 4 dimensions, both at strong and weak coupling. This includes describing strongly interacting gauge theories using their supergravity duals, and understanding gauge theories at intermediate coupling via integrability. It also includes using and developing new string-inspired twistor-space techniques to analyse QCD and N = 1 amplitudes at one loop level. I also plan to thoroughly investigate the implications of string theory for the physics of black holes.In particular I am interested in constructing and analysing black hole microstates - smooth horizon-less solutions that are very similar to the black hole asymptotically, but differ from the black hole at the location of the horizon. Counting and understanding these microstates via the AdS-CFT correspondence will help establish whether black holes should be thought of as ensembles of such microstate geometries.
