My research has focused on the gravitational aspects of string theory in both AdS/CFT and cosmology. In AdS/CFT I have generally been involved in examining and testing the correspondence beyond the protection of supersymmetry by both modifying boundary conditions and studying non-supersymmetric spacetimes with striking properties using the usual supersymmetric boundary conditions. In particular I have recently been involved in showing that the current constructions of asymptotically Lifshitz spacetimes, conjectured to be dual descriptions of relatively common condensed matter systems, suffer from a subtle inner singularity that can not be resolved by standard string theory effects and that imposing the usual boundary conditions forbids generic perturbations to the spacetime deep in the bulk. Cosmologically I am interested in singularity resolution, inflation and possible alternatives to inflation, de Sitter in string theory, and understanding the extent to which a string theory landscape exists. I have recently pointed out that the usual methods constructing purportedly long-lived de Sitter vacua actually result in relatively rapidly decaying states, once gravity and some technical subtleties are taken into account. As a result, it is not clear that any constructions currently understood result in long-lived de Sitter vacua, let alone large families of such solutions.
