I am a theoretical astrophysicist using numerical models to answer fundamental questions about the compact-object binaries detected by LIGO and the astrophysical environment in which they formed. I am interested in computational astrophysics and gravitational dynamics in general, with applications to supermassive black holes, nuclear star clusters and galaxy evolution.

Here at Cardiff I am a senior lecturer and STFC Rutherford fellow in the Gravity Exploration Institute.

Interests: Stellar dynamics. Black holes and gravitational wave astrophysics.

I am a theoretical astrophysicist using numerical models to answer fundamental questions about the compact-object binaries detected by LIGO and the astrophysical environment in which they formed. Using relativistic analytical calculations and numerical models of dense star clusters I study the formation of black hole mergers and gravitational waves in these systems. I am interested in computational astrophysics and gravitational dynamics in general, with applications to supermassive black holes, nuclear star clusters and galaxy evolution.
