Dr Paddy Dempsey (PhD) is a multidisciplinary medical research scientist, with groundings in human physiology, sport and exercise science and public health. He is a National Health and Medical Research Council (NHMRC) Postdoctoral Fellow currently based within the Physical Activity Epidemiology Programme at Cambridge University (UK), and continues to work in collaboration with several laboratories (Physical Activity, Behavioural Epidemiology and Metabolic and Vascular Physiology) at the Baker Heart and Diabetes Institute and Monash University in Melbourne, Australia — where he conducted his PhD studies.

Dr Dempsey utilises epidemiological, mechanistic/clinical and interventional research methods to enhance research discovery and translation. His research interests are currently focused on the role of physical activity, sedentary behaviour (i.e. the ‘activity spectrum’), and diet (including their interacting effects) in the prevention and management of chronic diseases — particularly type 2 diabetes and cardiovascular disease. He interrogates these areas using large epidemiological datasets (e.g. UK Biobank, EPIC, Fenland, AusDiab), meta-research, and through human intervention/clinical trials. His research on physical activity, sedentary behaviour and diabetes has been published in high-impact medical journals, has influenced international physical activity/exercise clinical guidelines for those with diabetes/hypertension, and has received international media attention.
