Dr Sandra Orgeig,
University of Adelaide
Sandra’s research examined the relationship between cholesterol and phospholipids in the pulmonary surfactant system throughout the evolution of the vertebrates. Pulmonary surfactant is a complex mixture of lipids (fats) and proteins that lines the inside of the lungs where it controls the surface tension and reduces the work of breathing. Sandra discovered that the lipid composition of the surfactant system is tightly regulated among the vertebrates, and is dependent on the body temperature of the species.
In 2007, Sandra moved to an Associate Professor position at the University of South Australia.
