Associate Professor Leonie Heilbronn is Group Leader of the Obesity and Metabolism group based within the Nutrition and Metabolism Theme at SAHMRI. Her research focus is to better understand the molecular and physiological basis of obesity and its co-morbidities, and in particular the role that insulin resistance plays in the aetiology of these conditions. Her research is at the interface between basic and clinical science, and she currently has research projects aimed at understanding mechanisms of insulin resistance in skeletal muscle and in adipose tissue utilising various environmental perturbations (e.g. overfeeding, calorie restriction, exercise, hyperbaric oxygen therapy). She is also keenly interested in the role of nutrition in healthy ageing and is a member of the Robinson Research Institute, where she also studies mechanism of insulin resistance in IVF.
