    Main Research Fields

    AGN: the temporal and spectral variability of Active Galactic Nuclei, especially concentrating on the mechanisms responsible for very high variability events.

    Tidal Disruption Events: X-ray and UV flares produced by the disruption of a star by the supermassive black hole at a galaxy nucleus.

    XMM-Newton slew survey: the production of a catalogue of X-ray sources detected while the XMM satellite moves between targets.
