Research
My main focus is near-field cosmology. This is the use of precision studies of kinematics, dynamics, stellar populations, chemical abundances, ... for the oldest systems in the local universe to deduce the fundamental properties of structure formation and the nature of dark matter in the early Universe. Current survey and 8-m telescopes are superb for this. The ESA satellite Gaia (launched December 2013) is revolutionising this field - and many others.

The Gaia-ESO Survey is a 450+ Co-I 400+night ESO-VLT Public Spectroscopic Survey. It is the largest large-telescope high-quality stellar spectroscopic survey, complementary to Gaia. The Co-PIs are Gerry Gilmore and Sofia Randich (Arcetri/Florence).

Gaia Science Alerts are the real-time discoveries from Gaia - see https://gaia.ac.uk
I was the first UK Scientific member of ESO Council on UK membership, during which time I negotiated the merger of competing interests and became first PI of the European Extremely Large Telescope, now under construction.

Early in my career I discovered the Galactic Thick Disk New light on faint stars – III. Galactic structure towards the South Pole and the Galactic thick disc | Monthly Notices of the Royal Astronomical Society | Oxford Academic (oup.com)
With PhD student Koen Kuijken I provided the first modern robust determination of dark matter near the Sun mass distribution in the galactic disc – I. A technique to determine the integral surface mass density of the disc near the Sun | Monthly Notices of the Royal Astronomical Society | Oxford Academic (oup.com) mass distribution in the galactic disc – II.

With student Roddy Ibata I discovered the Sgr dwarf galaxy, first evidence of present-day Galaxy mergers and accretion A dwarf satellite galaxy in Sagittarius | Nature
With student Pavel Kroupa I determined a robust stellar initial mass function of continuing application 1990MNRAS.244...76K (harvard.edu) among much else removing low-mass stars as a significant contributor to any baryonic dark matter, a topic of interest at the time.
Rosemary Wyse and I developed models and acquired data to interpret stellar chemical element ratios in terms of evolution for the Milky Way and dwarf galaxies. https://ui.adsabs.harvard.edu/link_gateway/1998AJ....116..748G/doi:10.10...
