I am a Lecturer in the School of Mathematics, Statistics and Physics at Newcastle University.

My research applies statistical methods to analyse large data sets from cosmological galaxy surveys. I use Bayesian parameter inference and model comparison, as well as machine learning techniques, to constrain and compare cosmological models. I am interested in inference in high-dimensional spaces and approximate modelling to accelerate inference within complex physical systems. Within this space, I have two main scientific focuses: astrophysical modelling uncertainties affecting weak gravitational lensing and galaxy clustering, and exploring the possibility of cosmological deviations from General Relativity.

I am a Full Member and Builder of the Rubin Observatory's Legacy Survey of Space and Time Dark Energy Science Collaboration (LSST DESC).
