Description | * I developed a new method for computing the gravitational self-force that drives the inspiral and merger of a pair of compact bodies (such as black holes) under gravitational attraction. * I made the first GSF calculation for a rotating black hole * I showed the connection between caustics in wave propagation around black holes, and the spectrum of black hole resonances known as quasinormal modes. |

Exploitation Route | One hundred years after Einstein developed his theory of general relativity, we are now on the verge of directly detecting gravitational waves -- propagating ripples in spacetime -- here on Earth. My work is part of an ongoing effort to understand how gravitational waves are generated by black holes. My work is relevant to anyone interested in the consequences of Einstein's theory, and the wide community of scientists who are seeking to "hear" the Universe for the first time. |

Description | My findings have been used by other researchers who are interested in black holes, their resonances (quasi-normal modes), and the propagation of waves on curved spacetimes. In particular, my work has advanced the "Gravitational Self-Force" programme, whose goal is to accurately model the motion and gravitational-wave emission of extreme mass ratio inspiral binary systems. Improved modelling of sources will contribute towards the experimental search for gravitational waves, and the nascent field of gravitational wave astronomy. |
