I am an RAS Research Fellow at the University of Hertfordshire. I am interested in the formation and evolution of stars and star clusters.
My main research concerns the dynamical structure of star clusters and what this can tell us about how stars and star clusters form and evolve. I use observations at a range of wavelengths from both ground and space-based observatories to study young stars in a number of different clusters and associations. I am also interested in how feedback from massive stars affects the formation and evolution of nearby low-mass stars and their protoplanetary disks, and how stars generate a magnetic dynamo and emit X-rays.
Press Release: Largest star known tearing itself apart|
The Royal Astronomical Society have produced a press release to support the publication of our paper on the ionized nebula surrounding the red supergiant W26 in Westerlund 1. The European Southern Observatory have almost prepared an image release of the star cluster.

An ionized nebula surrounding the red supergiant W26|
Using VPHAS Hα and HST images we have identified an ionized nebula surrounding the extremely large and evolved red supergiant W26. The nebula shows evidence of considerable recent mass-loss from the star with a possible polar outflow.

New UH astrophysics posters for schools have arrived! |
Thanks to a grant from the University of Hertfordshire we have produced and printed a series of posters that describe cutting-edge astrophysics research to school children. If your school wants some send me an email and we'll send you a pack!
