Senior Research Fellow of Cosmology, University of Portsmouth
I joined the ICG as a Senior Research Fellow in January 2022, supported by a Royal Society URF. Before that I was a McWilliams Fellow at Carnegie Mellon University, and before that a Junior Research Fellow at St John's College, Oxford. I obtained my PhD from Stanford University in 2017. I am interested primarily in developing new tests of the standard model of cosmology (gravity and/or dark sector physics) using astrophysical objects, mainly galaxies and stars. My work ranges from pure theory, through N-body and hydrodynamical simulations to statistical data analysis. I am also interested in galaxy formation and how best to characterise the relation between galaxies and their host dark matter halos.

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newtons law of gravity to their visible matter, despite those...
