I have held a SARAO Visiting Professorship at UWC since 2010, with my main job based at the University of Oxford. My research interests are on observational constraints on galaxy formation and cosmology. I lead the VISTA Infrared Deep Extragalactic Observations (VIDEO) Survey, and am the co-PI of of MeerKAT-MIGHTEE survey, along with Russ Taylor. I have also played a leading role in various optical, mid-IR and far-IR surveys along the way. I am a PI in LSST, and am the UK point of contact for the deep drilling fields. I also have ongoing interests in using Gaussian Processes in astronomy, in particular to determine photometric redshifts.
