My research centres around observations I make using astronomical satellites and large telescopes (like those on La Palma or Chile).
My current star formation programme tries to understand the global structure of star formation regions. This is could be termed "stellar archaeology"; poking around in what's left over after star formation has happened, to see what it can tell us about what went on. Much of the data I've used is from colour-magnitude diagrams and is available through the Cluster Collaboration's Home page. However, I am now becoming interested in the time-variability of young stars as well, hence my involvement in the Large Synoptic Survey Telescope where I Chair the Board for the LSST:UK Consortium.
Recently I have become interested in searching for Earth-mass exoplanets, which I carry out as Science Manager for the Terra-Hunting Project.
I have an active interest in observational techniques and algorithms, which includes statistical techniques such as my tau-squared method for fitting colour magnitude diagrams and optimal photometry technique.
Past research programmes I have run include measuring back holes masses by observing the stars orbiting around them and the evolution of classical novae. I also had a leading role eSTAR project, scheduling networks of automated telesscopes.
Fitting Colour-magnitude diagrams. This is the latest thing to hit my web pages. All the software you need to make quantitative fits to colour-magnitude diagrams.
Photometry Code. The documentation and code for my optimal photometry routines, which obtain the maximum signal-to-noise available for a stellar image.
Catalogues and Data for Star Forming Regions. The data for many of my papers is freely available on the Cluster Collaboration's Home page.
Publications via the Astrophysics Data System.
Contact Details such as address, phone number and the like are given on my School of Physics Home page.
