- Profile
-
My research interests involve the study of the birth, life and death of the most massive stars in the universe. Such stars are rare, but dominate the ionising budget of galaxies and the energetics of young stellar populations.
My primary scientific goals involve in the study of late evolutionary phases of massive stars, notably Wolf-Rayet stars. This is achieved via ultraviolet to infrared observations with large ground- and space- based telescopes (e.g. VLT, HST), plus sophisticated analysis tools.
I have revised the observed stellar mass limit upwards, discovered the first super star cluster in the Milky Way and established the metallicity dependence of Wolf-Rayet winds.
I have presented 4 invited review papers at international meetings in the past 5 years, published over 190 journal papers including a review paper in Annual Review of Astronomy & Astrophysics.

Primary research interests involve the study of massive stars in a variety of environments. Lightweight stars, like our Sun, make up the overwhelming majority of stars in our galaxy and live a long and fairly peaceful life.
In contrast massive stars are very rare and live short intensive lives, after which they undergo core-collapse resulting in a supernova explosion.
Massive stars play a major role in the ecology of their parent galaxies since they dominate the ionising budget of most galaxies and inject kinetic energy via stellar winds and supernovae.
My primary focus involves the study of late evolutionary phases of massive stars, notably Wolf-Rayet stars. This is achieved via ultraviolet to infrared observations of young stellar populations in the Milky Way and other nearby galaxies using large ground- and space- based telescopes (e.g. VLT, HST), plus sophisticated analysis tools.
Notable highlights involve the upwards revision of the observed stellar mass limit, the discovery of the first super star cluster in the Milky Way (Westerlund 1), and establishing the metallicity dependence of Wolf-Rayet winds. My current research team involves PhD student Thaer Alkousa, RA Joachim Bestenlehner and honorary professor Andy Pollock is associated with the group.
