Professor Stephen Simpson is Academic Director of the Charles Perkins Centre, a University of Sydney cross-faculty initiative aimed at researching and implementing cross-disciplinary approaches to alleviating the burden of obesity, diabetes, cardiovascular disease and related conditions, and is the Executive Director of Obesity Australia.
Stephen was born in Melbourne and grew up in Australia. After completing his undergraduate degree at the University of Queensland, he undertook his PhD at the University of London. Stephen spent 22 years at the University of Oxford, first in Experimental Psychology, then in the Department of Zoology and the Oxford University Museum of Natural History, before returning to Australia in 2005 as an Australian Research Council Federation Fellow, then ARC Laureate Fellow.
Stephen, with close colleague David Raubenheimer, developed an integrative modelling framework for nutrition (the Geometric Framework), which was devised and tested using insects. This has since been applied to a wide range of organisms, from slime moulds to humans, and problems, from aquaculture and conservation biology to the dietary causes of human obesity and ageing. He has also revolutionised understanding of swarming in locusts, with research spanning neurochemical events within the brains of individual locusts to continental-scale mass migration.
In 2007 Stephen was elected a Fellow of the Australian Academy of Science, in 2013 was elected a Fellow of the Royal Society of London as “one of the world’s foremost entomologists and nutritional biologists”, and in 2015 was made a Companion of the Order of Australia “for eminent service to biological and biomedical science.”
