I am an Royal Astronomical Society Research Fellow based at the University of Hertfordshire. My research concerns the formation and dynamics 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 wavelenths from both ground and space-based observatories to study young stars in a number of different clusters and associations. In particular I use high-precision imaging and spectroscopic observations to acquire radial velocities and proper motions for young stars to expose their kinematics and the dynamical processes at work in star clusters.
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: Over 200 million stars catalogued in the visible Milky Way|
The Royal Astronomical Society has made a press release to coincide with the 2nd data release from the IPHAS survey (which I've been involved in for over 10 years!). Included in the release is a stunning stellar density map from the survey with exquisite detail.

Paper published: The Chandra Cygnus OB2 Legacy Survey catalog|
After many years of hard work we've published a catalog of 8,000 X-ray sources in the Cygnus OB2 association from our 1 mega-second Chandra survey of the region. Expect many science papers using these results in the next few months!

Press news: The Guardian features our 'cosmic tadpole' image!|
In the Guardian's 'Month in Space' image section this month our HST/IPHAS image of one of the proplyd-like objects in Cygnus made top billing.
