The Genetic Epidemiology Group which investigates the implications and applications of genetic research to personal and public health. The work is interdisciplinary, integrative and collaborative. The Division of Population Health hosts several large, highly phenotyped population-based cohort studies that provide an excellent resource for genetic epidemiology. The group plays a central role in large-scale collaborative studies both nationally and internationally. There are close collaborations with groups engaged in health outcomes research and research using national disease registries. The aims of the group are thus closely aligned to those of the Division as a whole, which are to enhance the health of patients and populations by promoting public health and improving clinical care. The skills mix of epidemiological, clinical, statistical and behavioural science in the Division provides the scientific basis to underpin our internationally competitive programme.
