About Dr Nathan Johnson

Dr. Johnson's research interest centres on understanding the role of fat metabolism in health and disease.

Dr. Johnson undertakes basic research on fat metabolism and its interaction with exercise, health and disease. His research centres on exercise physiology, but the scope of his work spans the areas of obesity, insulin resistance, type 2 diabetes and fatty liver. A theme of this work is the development and application of non-invasive magnetic resonance techniques for the assessment of human physiological function. Dr. Johnson's current research projects focus on the application of novel exercise and dietary strategies to reduce cardio-metabolic risk.
