Garry is an Associate Professor of Exercise and Health Sciences at Northumbria University. He studied sport and exercise science through his undergraduate and postgraduate years, with a keen interest on physiological and functional adaptations to exercise training. His postdoctoral research began in 2006 at Sheffield Hallam University where he completed a PhD in the physiological effects of exercise training in people with peripheral vascular disease. He has gone on to lead several randomised controlled trials of exercise training in a range of clinical populations, including inflammatory bowel disease, abdominal aortic aneurysm, prostate cancer, and older adults with multimorbidity. His research aims to improve the evidence base for exercise training in the management of chronic disease.
