My research interests lie broadly in the fields of observational cosmology and galaxy formation and evolution. A key aim of my research is to bring together multi-wavelength data from very large "wide-field" optical and infrared digital sky surveys in order to discover new populations of luminous galaxies and accreting supermassive black holes (quasars) in the distant Universe. Using follow-up spectroscopic and photometric observations of these newly discovered systems, I then try and understand the physical processes going on within them e.g. star formation, accretion, inflows and outflows, all of which modulate the galaxy formation process.

Currently I am actively working on new optical data from the Dark Energy Survey (DES) and infrared data from the VISTA extragalactic imaging surveys. I am Principal Investigator for the new VISTA VEILS survey, which has been allocated almost 1200 hours of telescope time on the VISTA telescope between 2017 and 2020. Within the DES collaboration I co-lead the Galaxy Evolution & Quasar Science Working Group.

I am also interested in studying galaxies and quasars at X-ray, far infra-red and millimeter wavelengths. In recent years I have used data from instruments such as XMM-Newton, Herschel, SCUBA-2, ALMA and the VLA in order to better understand both supermassive black hole accretion and the distribution of dust and molecular gas in galaxies.

I am actively involved in several next-generation extragalactic wide-field spectroscopic surveys such as 4MOST and VLT-MOONS. In particular, I am working on target selection strategies for both high redshift galaxies and quasars for these upcoming spectroscopy experiments.
