Main Research Fields
Time series Analysis - Black holes - Accretion - Relativity
My research involves the application of novel analysis methods to astronomical data. The main focus is time series analysis of light curves from accreting compact objects (black holes and neutron stars), where the goal is to understand gravity in the strong field regime, extreme physics and the role these objects play in shaping the universe.
In particular, I use X-ray reverberation mapping and quasi-periodic oscillations (QPOs) to study matter spiralling in the inner accretion flow around a black hole. I am currently working on neural network methods to find important signals in the presence of red noise.

XMM-Newton science group
Accretion Journal club
I run a weekly journal club where we discuss recent results relating to accretion onto compact objects, feedback, time domain astronomy, GR and big-picture science.
This is currently a virtual meeting. We use the arXiv organising site https://www.benty-fields.com "ESAC Accretion". Message me to be included on the mailing list.
