Black Hole

Lensing of space time around a black hole. At Oxford we study black holes observationally and theoretically on all size and time scales - it is some of our core work.

I am a Royal Society University Research Fellow at the Institute of Cosmology and Gravitation, University of Portsmouth.

My research sits at the interface of cosmological large-scale structure and galactic astrophysics, studied through the lens of advanced statistical and machine learning methodologies. A particular focus is field-level inference by means of Bayesian forward modelling, which I have used to constrain modified gravity, dark matter microphysics and other facets of new fundamental physics, as well as infer the structure, velocity field and formation history of the local Universe. My work is geared towards extracting the maximum amount of information possible from current and upcoming galaxy surveys in a statistically rigorous manner, with the aim of developing precise and novel tests of LCDM.
