Overview

My research is focused on the formation and evolution of galaxies through statistical studies of galaxy surveys. I have worked on all stages of a range of galaxy survey projects: the design of surveys; the observational data collection; data reduction, database management; data analysis and the interpretation of the results.

Teaching

I have been teaching for 15 years and lectured on subjects ranging from introductory astronomy to advanced high-energy astrohphysics, from practical lab physics, to Fourier techniques and image processing. Most recently I contributed lectures and hands-on computing sessions for a Data Analysis module.

I have taught at the University of Nottingham, the Universtity of Canterbury, and The University of Cardiff. I hold a Post Graduate Certificate in Academic Practice awarded by the University of Nottingham.

    My research is focused on the formation and evolution of galaxies through statistical studies of galaxy surveys. I have worked on all stages of a range of galaxy survey projects: the design of surveys; the observational data collection; data reduction, database management; data analysis and finally the interpretation of the results.

    My analysis of galaxy clustering in the APM Survey (Maddox, Efstathiou, Sutherland and Loveday, 1990, MNRAS 242,43) led to one of the first recent pieces of evidence for the currently popular idea of a Cosmological constant (Efstathiou, Sutherland and Maddox 1990 Nature 348, 705). These papers have 610 and 479 citations respectively.

    I was the UK PI of the 2dF Galaxy Redshift Survey, which used the Anglo-Australian telescope to map the positions of 250000 galaxies in the southern sky. The 2dFGRS team won the Royal Astronomical Society Group Achievement Award in 2007 for our work. One of the main results from the survey was the first detection of baryon oscillations in the galaxy distribution; two team members were awarded the Shaw Prize in Astronomy 2014 for this work. The 2dFGRS description paper (Colless, Dalton, Maddox et al 2001 MNRAS 328 1039) has 1744 citations and continues to average about 100 citations per year, even 19 years after publication.

    More recently I have been working on the Herschel-ATLAS survey, which is the largest ever sub-mm galaxy survey. The consortium now includes over 160 members in over 60 institutes around the world. I was a founding a member of the H-ATLAS executive committee and leader of the large-scale structure working group.

    So far the H-ATLAS survey has produced 114 refereed journal publications with over 5000 citations.

    My main contribution to these papers has been to create the source catalogues and flux measurements used in the analyses.

    Since moving to the University of Cardiff I have continued to work on the H-ATLAS and follow-up data, including reduction and analysis of 3-D spectroscopic data and development of a Bayesian approach to fitting chemical evolution models to a wide range of observational data.
