I am Professor of Biostatistics and Epidemiology at the Institute of Life Science. I lead the Biomarkers and Genes Research Theme, and am involved in a wide range of projects based on the application of statistical models to problems in biogical, medical and environmental sciences. My first degree was Natural Sciences at Cambridge, followed by a DPhil at the Department of Zoology at Oxford, supported by a NERC award. I took an MRC Fellowship to the Institute of Molecular Medicine at Oxford University (now the Weatherall Institute) and then joined a large BBSRC project during the BSE crisis to work at the Institute for Animal Health, Compton. I joined the Swansea College of Medicine as a Senior Lecturer in 2003, and was appointed to a personal Chair in 2007. My research ranges from analysis of large linked health databases (within the PPHI College Research Theme), to modelling of infectious diseases, statistical models of viral evolution (with colleagues in San Diego and Cambridge) and biomarkers for the impact of climate change on environmental systems (with colleagues at Deakin University, Australia).
