I am Professor of Extra-Galactic Astronomy at the Institute for Astronomy, an institute within the School of Physics and Astronomy at the University of Edinburgh and also part of the Scottish Universities Physics Alliance. I am a Fellow of the Royal Society of Edinburgh and of the Institute of Physics, and currently hold a European Research Council Advanced Fellowship and a Royal Society Wolfson Research Merit Award. My research interests are in extragalactic astronomy and cosmology: galaxy formation and evolution, the cosmic history of star formation, the first galaxies and cosmic reionization, and the connection between the growth of galaxies and black holes.
