Research summary

My research interests have largely involved the investigation of the most massive and luminous hot stars in galaxies, together with studies of the gas and dust in the interstellar medium. Particular emphasis has been placed on studying the physical and chemical nature of Wolf-Rayet stars, their mass loss properties and evolutionary status. This has involved spectroscopic studies in many wavebands using both space satellites and ground-based telescopes, notably in the ultraviolet (using the IUE satellite), in the X-ray domain (using the ROSAT and ASCA satellites), in the mid-infrared (using the ISO satellite) and in the optical using telescopes at the Anglo Australian Observatory and the La Palma observatory.
