Susanne von Caemmerer obtained her BA (Hons) in Pure Mathematics in 1976 (ANU) and her PhD in Plant Physiology in 1981 (ANU). She is now Professor of Molecular Plant Physiology at the Research School of Biology. She was elected to the Australian Academy of Science and Leopoldina (the German Academy of Science) in 2006. Her research focuses on photosynthesis and stomatal function, with an emphasis on the mathematical modeling of the carbon acquisition of plants, the biochemistry of carbon dioxide fixation and regulation of carbon dioxide diffusion in leaves. She is an Associate Editor for Plant Physiology and sits on the Editorial Board of Plant, Cell and Environment. She is also a member of the C4 Rice Consortium a group multidisciplinary scientist from around the world working together to discover genes that will supercharge photosynthesis in rice to boost food production in the developing world.
CO2 fixation and water loss of leaves. We are investigating aspects of carbon acquisition by plants including the biochemistry of CO2 fixation and regulation of CO2 diffusion into and within leaves.
Current research topics include:
- Studies on the biochemical regulation of C3 and C4 photosynthesis
- Physiological and molecular regulation of stomatal movement.
- CO2 diffusion inside leaves.
