Professor within the Astrophysics research cluster in the School of Mathematical & Physical Sciences at the University of Sheffield (Department of Physics & Astronomy until Aug 2024).
My primary research interests involve studies of massive stars in the Milky Way and other star-forming galaxies, for which I have co-authored 200+ refereed papers, including an Annual Review article on the Properties of Wolf-Rayet stars and co-authored a monograph From luminous hot stars to starburst galaxies, published in the Cambridge Astrophysics Series.
I have written about the 'Birth, life and death of massive stars' for Astronomy and Geophysics from the 2012 International Astronomical Union (IAU) General Assembly (GA), the Tarantula Nebula for Galaxies in 2019 and the connections between stellar evolution and feedback for a Lorentz workshop in 2022.
The above image shows the LMC giant star forming region, the Tarantula Nebula, and its dominant ionising star cluster R136. The brightest sources in R136 were the focus of a study that I led a study which resulted in a 'Stars just got bigger' press release from ESO in July 2010. Read the FAQ page or watch the Deep Sky Videos film for more information. The recent HST/VLT initiative ULLYSES/XshootU has permitted a major new study of hot luminous stars at low metallicity - see ESO Messenger article.
Current research
Current research
Current activities involve a deep Chandra X-ray study entitled Tarantula – Revealed by X-rays (T-ReX) ,VLT/MUSE observations of the central ionised nebula NGC2070, the ULLYSES-XshootU involving high quality UV and optical spectroscopy of Magellanic Cloud OB stars, plus BLOeM which is an ongoing VLT/FLAMES survey of the SMC to quantify the binary fraction of massive stars at low metallicity.
Research group
Research group
My research group comprises one PhD student (Thaer Alkouosa) and one honorary researcher (Andy Pollock). Postdoc Joachim Bestenlehner took up a new position in Aug 2024. Masters level research projects are closely related to my research interests, for example the Wolf-Rayet database assembled by two MPhys students.
Outreach
Outreach
I've contributed to the Deep Sky Videos channel and co-organised Sounds of the Cosmos – a performance of the Planets Suite with astronomy visuals by graphic designers Human interspersed with a short narrative overview of astronomy for Festival of the Mind.
The performance was recommissioned for 2015 Doc/Fest involving a reworked version of Doc/Fest: Sounds of the Cosmos at the Crucible Theatre. A further performance took place at the 2015 Latitude Festival. A new VR (mixed reality) exhibition: A Virtual Voyage Through the Milky Way previewed during Festival of the Mind 2024!
