Rate My Professor Stuart Gray

Professor Stuart Gray serves as Professor of Muscle and Metabolic Health in the School of Cardiovascular & Metabolic Health at the University of Glasgow, part of the College of Medical, Veterinary & Life Sciences. He earned his BSc in Physiology and Sports Science from the University of Glasgow and his PhD in Exercise Physiology from the University of Strathclyde. Following postdoctoral research positions at the University of Strathclyde and Loughborough University, Gray was appointed Lecturer at the University of Aberdeen. In 2015, he joined the University of Glasgow's School of Cardiovascular & Metabolic Health, advancing to his current professorial role. He contributes to teaching on the Distance Learning MSc in Sport and Exercise Science and Medicine and supervises PhD students on topics including iodine nutrition, thyroid disease, metabolism, dietary interventions for ageing, and muscle-strengthening exercises.

Gray's research centers on developing strategies to combat age-related muscle mass loss, or sarcopenia, and linked metabolic disorders. Key investigations examine the synergistic impacts of resistance exercise and omega-3 fatty acids on muscle function, utilize novel analytical methods to elucidate sarcopenia mechanisms, explore high-intensity interval training's potential as a public health intervention, and address fatigue etiology in rheumatic diseases through collaborations. He has obtained substantial grants from organizations such as the Medical Research Council, Biotechnology and Biological Sciences Research Council, British Heart Foundation, and Dunhill Medical Trust for studies including krill oil's effects on older adults' muscle function, resistance exercise for long COVID recovery, insulin resistance in South Asians, and nutritional strategies for diabetes prevention. Notable publications include 'The effect of krill oil supplementation on skeletal muscle function and size in older adults: a randomised controlled trial' (Clinical Nutrition, 2022), 'Resistance exercise therapy for long COVID: a randomized, controlled trial' (JAMA Network Open, 2025), 'Associations of Dietary Protein Intake With Fat-Free Mass and Muscle Strength Across the Life Course' (American Journal of Epidemiology, 2018), and 'The impact of the time of day on muscle and metabolic responses to resistance exercise in healthy adults: a randomised controlled trial' (Experimental Physiology, 2025). His work advances interventions for metabolic health in ageing, diabetes, obesity, and cardiovascular conditions.
