About
I am an Associate Professor in the School of Mathematical Sciences at Southampton, working in the Gravity group and the STAG Research Centre. My research sits where astrophysics meets statistics. I use observations of gravitational waves and pulsars to learn about black holes, neutron stars, and the extreme physics that governs them.
Much of my work is about inference: how to extract reliable conclusions from noisy, complicated data. This includes Bayesian parameter estimation, simulation-based and machine-learning methods, hierarchical population inference and detector characterisation. I help develop Bilby, an open-source inference library widely used in gravitational-wave astronomy, and I currently lead an STFC-funded programme on artificial intelligence for gravitational-wave astronomy.
Within the IGWN collaboration, I am Project Scientist for the Gravitational Wave Transient Catalogue. I have previously co-chaired the Compact Binary Coalescence and Parameter Estimation groups within LIGO.
