Teaching
During the 2019/20 academic year I teach on the following modules:
- PA1710 - Mathematical Physics 1.1 (module leader; instructor for units 4 and 5)
- PA1900 - Experimental Physics 1 (computing workshops)
- PA2720 - Statistical Physics (module leader, instructor for unit 1)
- PA2900 - Experimental Physics 2 (computing unit, data handling unit)
- PA3900 - Third Year Project (supervisor)
- PA4602 - Scientific Data Analysis (module leader)
- PA4900 - Fourth Year Specialist Research Project (supervisor)
- PA4440 - Fourth Year Literature Review (supervisor)
- plus academic and personal tutorials with Y1-4 students
Software
As part of my research I often develop software tools for data analysis. Where possible I make the more useful ones publicly available. See my Github page.

Research
My research includes the study active galactic nuclei (AGN), gamma-ray bursts (GRBs) and black hole X-ray binariesin our Galaxy. My particular research interests include probes of strong gravity, time series astronomy, Bayesian data analysis in astronomy, and dust-scattering from GRBs (I discovered the first known example of the latter phenomenon in 2004).
I've published more than 100 refereed papers, and received well over 6,000 citations to date. I have extensive experience with data from ESA's Cornerstone X-ray mission XMM-Newton (including being PI or Co-I on several "Large Programmes"), NASA's Great Observatory Chandra, NASA's RXTE and the joint US-UK-Italy mission Swift as well as many previous high-energy astronomy missions. I've been awarded guest observer time as PI on all these missions and was a member of a Working Group and Science Team for future ESA mission Athena.
One of my research areas is astrostatistics, especially time series analysis. I've published several papers on the use (and misuse) of statistical analysis in astronomy.
