Emeritus Professor in the Department of Physics+44 (0) 191 33 43605


I first came to Durham as a graduate student in 1989 after completing an M.A. in Cambridge. I spent three and a half years here on my thesis (Gravitational Lensing by Rich Clusters) with Richard Ellis as my advisor. In 1993, having submitted my thesis, I left Durham for sunny southern California to take up a NATO Advanced Fellowship in the Physics, Math and Astronomy Division of the California Institute of Technology in Pasadena. I spent 18 months at Caltech before moving my fellowship two miles up the hill to the Observatories of the Carnegie Institution of Washington on Santa Barbara Street. When my NATO Fellowship finished I stayed on at OCIW as a Carnegie Fellow for a year and then took up a PPARC Advanced Fellowship back in Durham at the beginning of 1996. In 1998 I traded in the PPARC AF for a Royal Society University Research Fellowship which was renewed until 2008 when I moved onto the academic staff of the Physics Department. I was awarded a Philip Leverhulme Prize Fellowship in 2001 in recognition of my research and a Chair in the Department of Physics at Durham in 2004.

I am a Professor of Physics in the Centre for Extragalactic Astronomy within the Ogden Centre for Fundamental Physics. I was the Founding Director of the Centre, as well as Managing Director of the Durham Astronomy Research Cluster (DARC). I was awarded a Leverhulme Fellowship in 2011. In 2012 I was awarded an European Research Council Advanced Programme grant to support my DustyGal research programme until 2018, along with a Royal Society/Wolfson Merit Award. I have been ranked as one of the most highly-cited researchers in Space Sciences since 2015.
