Biographical details

Professor Stephen Simpson is the Academic Director of the Charles Perkins Centre and an Australian Research Council Laureate Fellow in the School of Biological Sciences at the University of Sydney.

Steve returned to Australia in 2005 after 22 years at Oxford where he was Professor of Entomology and Curator of the University Museum of Natural History. He holds a PhD from the University of London, and an Honours degree from the University of Queensland.

Steve co-developed a nutrition modelling framework that was devised and tested using insects, but has since been applied to humans. The framework tackles the dietary causes of human obesity and ageing.

In addition to nutritional biology, Steve’s research on locusts has led to an understanding of locust swarming that links chemical events in the brains of individual insects to landscape-scale mass migration.

Steve has been Visiting Professor at Oxford, a Fellow of the Institute for Advanced Study in Berlin, Distinguished Visiting Fellow at the University of Arizona, and Guest Professor at the University of Basel.

In 2007, he was elected a Fellow of the Australian Academy of Science, in 2008 he was awarded the Eureka Prize for Scientific Research, in 2009 he was named NSW Scientist of the Year, and in 2010 he was named as the Wigglesworth Medallist by the Royal Entomological Society of London.

Steve took up the Academic Directorship of the Charles Perkins Centre at the University of Sydney in April, 2012.

Research interests

My group works at the interface of physiology, ecology, and behaviour. As well as discovering the mechanisms that induce swarming in locusts (research which now spans events within the nervous system of individual locusts to mass migration), we have, in collaboration with longstanding colleague David Raubenheimer (Massey University), developed a novel class of state-space models for nutrition, called the Geometric Framework (GF). The GF arose from extensive experiments on insects, but is now being applied in a wide variety of contexts, including conservation biology, human health, gerontology, immunology, ecology and aquaculture. Leads the Behaviour and Physiology Research Lab The Behaviour and Physiology Research Group (BPRG), studies the neural, physiological, ecological and evolutionary bases of animal behaviour. The group's emphasis is 'bottom-up', in that we are especially concerned with the way in which lower-level processes lead to higher level outcomes. Our approach focuses on the behaviour of individual organisms and involves an interplay between theory and experiment. Most of our experimental work is on insects, although recent work has examined fish, birds and mammals - including humans. Techniques employed include the quantitative analysis of behaviour, neurophysiology, metabolic and digestive physiology, mathematical modelling, computer simulations and laboratory selection experiments.
