I am a plant ecologist with a background in plant ecophysiology and 20 years experience of working in the Old World tropics. I grew up in the west country of England and have held lectureships at British universities, but now work for CSIRO, the Australian national scientific research organisation where I lead the Ecology Research Program. Current projects are mostly focussed at the landscape scale, and include work on weeds, fire management and threatened species. I am also interested in the biogeography and evolutionary history of Australian tropical rain forests, which have significant relationships with South America, Madagascar, New Caledonia and South-east Asia.
