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.

Paper published: New OB star candidates around Westerlund 2 from VPHAS+|
We introduce, trial and validate a method to photometrically identify OB stars using VPHAS+ photometry, and present 356 OB star candidates near the Westerlund 2 star cluster.

Paper published: Classical Be stars in the Perseus Spiral Arm|
We present a catalogue of 247 new classical Be stars discovered towards the Perseus spiral arm, allowing the structure of the spiral arm to be constrained.
