Professor Scott's research focuses on age-related changes in skeletal muscle mass and function (sarcopenia), bone health (osteoporosis) and adiposity (obesity), their effect on risk for falls, fracture and disability in older adults, and exercise and nutrition approaches for their prevention and management. He leads clinical trials exploring the effects of exercise and nutrition interventions, including weight loss, on improving body composition, physical function and bone health in older populations. He is a member of the Committee of Scientific Advisors for the International Osteoporosis Foundation, and is also the Chair of the Australian and New Zealand Society for Sarcopenia and Frailty Research's Sarcopenia Diagnosis and Management Task Force. He has led several activities focused on improving clinical awareness and management of sarcopenia and has published over 270 journal articles and book chapters
