Research


My research interests are pulsar searching and timing. In particular I am working on searches for relativistic binary pulsars such as compact double neutron star systems or even pulsar black-hole binaries. I have also been searching for pulsars around Sagittarius A*, the supermassive black hole candidate at the centre of the Milky Way. All of these systems can be used for precision tests of theories of gravtitation.

I'm also a member of the BlackHoleCam project team.
