I am a visitor at Oxford, and a Lecturer in Astrophysics and Royal Society University Research Fellow at Newcastle University. I completed my PhD at the University of Durham in 2012, and was awarded the 2012 Michael Penston Thesis Prize, for the best astronomy PhD thesis in the UK that year, by the Royal Astronomical Society. I then moved to the University of Amsterdam, first as a postdoc (2012-2014) and then as an NWO Veni research fellow (2014-2017). I moved to Oxford to start my University Research Fellowship in October 2017 and left in October 2021 to become a Lecturer at Newcastle.

My research focuses on accreting compact objects, mainly stellar-mass black holes accreting gas from their binary partner in a so-called X-ray binary system, but I am also interested in accreting neutron stars and active galactic nuclei. I analyse and model X-ray observations of these systems in order to learn about the very strong gravitational field present close to the event horizon. In particular, I develop and use sophisticated techniques that exploit the rapid stochastic variability seen in the X-ray signal in order to map the accretion flow in the immediate vicinity of the black hole. This includes using Doppler shifts to detect a wobble of the inner accretion flow predicted by General Relativity known as Lense-Thirring precession, modelling aperiodic X-ray variability as inward propagating fluctuations of the density of the accretion disk, and using light crossing delays for the purposes of reverberation mapping.
