Dr Simon Vaughan is a reader in Observational Astronomy at the University of Leicester, and also Undergraduate Administrator. His research includes the study active galactic nuclei (AGN), gamma-ray bursts (GRBs) and black hole X-ray binaries in our Galaxy.

His particular research interests include probes of strong gravity, time series astronomy, Bayesian data analysis in astronomy, and dust-scattering from GRBs (he discovered the first known example of the latter phenomenon in 2004).

His research also uses observations of cosmic x-ray sources to study physics under extreme conditions, in particular, close to black holes.
