Trosolwg
My research focuses on the detection and study of gravitational waves -- ripples in the fabric of spacetime. These are produced by some of the most violent events in the Universe, such as the collisions of black holes, the explosive deaths of massive stars, and perhaps the Big Bang itself. The detection of gravitational waves by the LIGO observatories has opened a new window on nature, and is allowing us to probe the behaviour of matter and test Einstein's theory of gravity under extreme conditions that cannot (and should not!) be replicated on Earth. My particular specialties are the detection and interpretation of weak signals in noisy data. I am a member of the LIGO Scientific Collaboration, and have served on various national and international advisory committees on gravitational waves and astroparticle physics.
Bywgraffiad
I undertook my graduate studies at the University of Alberta, studying the renormalisation of quantum field theories in curved spacetimes, and graduated in 2000. I then spent two and a half years as a postdoctoral fellow in the gravitational physics group at Penn State University, followed by a four-year stint as a senior postdoctoral fellow and then a senior research fellow at the California Institute of Technology. I joined the faculty of Cardiff University as a senior lecturer in June 2007, and was promoted to Reader in 2012 and then Personal Chair in 2016.

Research interests
Violent relativistic events such as the collisions of black holes or neutron stars, supernovae, and gamma-ray bursts, can produce powerful bursts of gravitational waves. A common feature of these systems is that they are difficult to model, involving complex physics of matter at nuclear densities and nonlinear general relativistic effects. Gravitational waves could provide a probe of the rich physics of these systems. As a member of the LIGO Scientific Collaboration, I am developing strategies to detect gravitational-wave bursts, and creating techniques for locating the sources on the sky, extracting their waveforms from noisy data, and fitting them to simulations and theoretical models. In particular, I focus on the detection of gravitational waves associated with gamma-ray bursts and supernovae using data from the LIGO, GEO, and Virgo detectors.
