I'm a Professor within the Astrophysics group, Director of Learning and
Teaching (until 31 Aug 2016) and interim Head of Department (from 1 June 2016) in Physics and Astronomy at
the University of Sheffield.
The above image shows the LMC giant star forming region, the Tarantula Nebula, and its dominant ionizing 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 (see FAQ and Deep Sky Videos film). Current research activities involve a HST/STIS spectroscopic study of the R136 cluster, see Hubble unveils monster stars Press Release from ESA in March 2016, an ESO Large Programme VLT/FLAMES Tarantula Survey, plus a deep Chandra X-ray study entitled Tarantula - Revealed by X-rays (T-ReX).
I also teach astrophysics modules on Stellar Atmospheres (PHY305), Stellar Evolution (PHY404) and Astrophysics (PHY104). Undergraduate 3rd and 4th year projects are closely related to my research interests, e.g. Wolf-Rayet database assembled by two M.Phys students.
I'm involved in a variety of outreach activities, including the Deep Sky Videos channel. Together with Stewart Campbell, i've co-organised Sounds of the Cosmos, involving 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. This was recommissioned for 2015 Doc/Fest involving a reworked performance of Doc/Fest: Sounds of the Cosmos at the Crucible Theatre. A further performance took place at the 2015 Latitude Festival - see link.
