Dr Amanda Brandon

Research Officer

Amanda Brandon undertook a PhD in fetal and neonatal physiology, under the supervision of Drs Karen Gibson and Amanda Boyce at UNSW. The major component of the project was to investigate the effects of maternal renal dysfunction on the developing offspring (developmental origins hypothesis) in an attempt to uncover if their renal, cardiovascular or renin angiotensin systems had been programmed by this altered in utero environment.

Since obtaining her doctorate in 2007, Amanda has been working as a Post-Doctoral researcher at the Garvan Institute in the Diabetes and Metabolism Division under the supervision of Profs Ted Kraegen and Gregory Cooney. This is a world renowned research group in the field of diabetes, with a particular interest in the role of lipid accumulation in skeletal muscle in the development of insulin resistance and type 2 diabetes.

Amanda has used nutrient overload models (hyperglycaemia and high fat diet) to examine how excess nutrients cause insulin resistance in skeletal muscle and whether we can intervene to prevent its development. More recently she has trained in euglycaemic-hyperinsulinaemic clamp technique in mice using the dual cannulation methodology (the gold standard).
