Associate Professor David Frazer is the Head of the Molecular Nutrition Laboratory at QIMR Berghofer and he has been investigating the role of iron in health and disease for over 20 years. He joined QIMR Berghofer in 1998 as a PhD student and began examining the molecular basis of intestinal iron absorption and its regulation. Following his PhD, David remained at QIMR Berghofer and continued to research iron-related diseases as a Post-Doctoral scientist in the Iron Metabolism Laboratory. He is now Head of the Molecular Nutrition Laboratory and his current work focuses predominantly on the development and use of novel iron supplements to treat iron deficiency, examining how mutations in HFE lead to iron loading in hemochromatosis patients and investigating the molecular basis of iron homeostasis during pregnancy and infancy.
