Research Interests

    My research is primarily in classifications of supergravity solutions. As supergravity theories describe the low-energy
limit of string theory/M-theory, a better understanding of the solutions of supergravity theories is required. I have worked
on a number of projects constructing classifications of supersymmetric solutions of a number of supergravity theories,
both in low (D=4,5) and in higher (D=10,11) dimensions.

     These classifications are constructive, i.e. they provide algorithms for finding new solutions, such as new black holes.
Examples of these are new asymptotically Anti-de-Sitter black holes in five dimensions, and new, asymptotically
flat "black Saturn" solutions, consisting of an arbitrary number of concentric black rings with a black hole in the
middle. Black hole uniqueness theorems can also be constructed using related techniques. In a number of cases, it is
also possible to prove non-existence theorems, for example, I have worked on proofs that there are no solutions preserving
31/32 of the supersymmetry in D=11 supergravity, and also no solutions preserving 29/32, 30/32 or 31/32 of the
supersymmetry  in type IIB supergravity in ten dimensions. By expanding on this programme of classification, it will
be possible to  come to a better understanding of the types of solutions which are of importance in the context of 
black hole physics and string theory.
