My research primarily involves investigating so called ‘Extreme Mass Ratio’ PSR-BH binaries. These systems provide some of the most aggressive and extreme environments in the universe and are the perfect testing ground for general relativity and fundamental physics.
In particular, my current research involves attempting to determine the theoretical timing signal from a pulsar in a relativistic orbit around a massive black hole. Such systems are believed to exist at the centre of galaxies and globular clusters, although none have yet been detected. Such work is important to both inform the detection of these systems, and to provide a theoretical template to then compare with observation for tests of fundamental physics.
