My research interests lie broadly in the fields of observational cosmology and galaxy and AGN 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 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 onto the supermassive black hole and feedback/outflows driven by the AGN. Currently I am actively working on new optical data from the Dark Energy Survey and infrared data from the VISTA surveys. Within the Dark Energy Survey collaboration I co-lead the Galaxy Evolution Science Working Group.
I also study galaxies and quasars at X-ray and far infra-red/submillimeter wavelengths in order to better understand both supermassive black hole accretion (investigated using X-ray data) and dust-obscured star formation (investigated using far infra-red/submillimeter data).
Finally I am also actively involved in the design and scientific optimisation of next-generation extragalactic wide-field spectroscopic surveys like 4MOST. In particular, I am working on target selection strategies for both high redshift galaxies and AGN for these upcoming spectroscopy experiments.
