his career has included postdoctoral work at the University of Alaska, Fairbanks, where he examined the impact of Arctic climate change on ecosystem structure and function and the effect of ecosystem changes on regional climate change and variability. He has played a leading role in OzFlux, an Australian network of Flux Towers, including the establishment of many long term flux sites in key ecosystems (Savanna, Mountain Ash forest, Urban, Pasture, Woodland, etc.). He has been awarded numerous Australian Research Council (and other) grants for projects that inform national and international strategies for managing climate change. He currently holds an ARC Future Fellowship focusing on “Savannas: Past, Present and Future”.
