Biography

I work on understanding the dynamics of savanna ecosystems in the context of global change. My work integrates field ecological data, remote sensing, modelling, and biogeochemistry. I am involved in collaborative research projects with Yale University, Edinburgh University and the University of Liverpool among others which variously work on fire-grazer interactions, inter-continental savanna comparisons, the importance of land-atmosphere feedbacks, and pursuing a global theory of fire. I am closely linked with research projects at the Global Change and Ecosystems group at the CSIR where I hold an affiliate position.
I teach undergraduate courses in Fundamentals of Ecology, Whole Plant Physiology Functional Ecology in Changing Environments. I also teach a 2 week MSc course on systems ecology called "Maintaining Ecosystem Processes"
