ABOUT ME

Biography

I am a metabolic biochemist and physiologist. My research interests focus on understanding how changes in metabolism affect both normal physiology and disease states. My lab is currently focused on therapeutic strategies to prevent metabolic decline in normal ageing and drug discovery for molecules that correct obesity and fatty liver disease. We are interested in most metabolic questions and have collaborations investigating how changes in glucose metabolism affect immune system function and understanding how metabolic physiology is altered in polycystic ovarian syndrome.
