After completing a PhD in geophysical fluid dynamics at RSES, ANU, in 1979 (working on double-diffusive convection with Professor J.S. Turner, FRS) I spend 3 years as a Postdoctoral researcher in the Department of Applied Mathematics and Theoretical Physics, University of Cambridge, UK, where my research focused on laboratory experiments with rotating flows and the instability of ocean currents. I then spent a year in France as a Research Associate in the Institute of Mechanics, University of Grenoble and CNRS. In 1983 I moved to RSES, ANU as a Research Fellow and in 1986 I joined the tenured faculty there, becoming a full Professor in 1999.
I was elected Fellow of the Australian Academy of Science in 2001, Fellow of the American Geophysical Union in 2001, Inaugual Fellow of the Australasian Fluid Mechanics Society in 2011, and Fellow of the Australian Institute of Physics in 1991. I was awarded the Centenary Medal for services to science in Australia in 2001, a Japan Society for the promotion of Science Invitation Fellowship in 1997, the Priestley Medal of the Australian Meteorological and Oceanographic Society in 1991, and a Postdoctoral Fellowship for the Geophysical Fluid Dynamics Summer Program, by Woods Hole Oceanographic Institute in 1980. I proposed, designed and managed construction of a new building housing the ANU's GFD laboratory and environmental isotope geochemistry facilities, formally opened in 2000. I was Interim Director of the Research School of Earth Sciences, ANU, for 6 months in 2006 and head of the Earth Physics section of the School 2006-2010.
I am an Associate Editor of the Journal of Fluid Mechanics, which is published by Cambridge University Press and one of the most respected research journals in the field. I encourage researchers to submit research articles on original work of interest in any area of fluid mechanics, and particularly in geophysical fluid dynamics. You can submit articles to me or any of the Associate Editors online through ScholarOne at http://mc.manuscriptcentral.com/jfm.
My present work concerns the fundament physics of convection, along with its implications for the dynamics of the ocean overturning circulation, which contributes to transport of heat from low to high latitudes in the earth's climate system and is largely responsible for setting the deep ocean stratification. I am also exploring turbulent mixing in various situations, including how small-scale turbulent mixing affects the large-scale ocean circulation. These questions are being addressed through simple theoretical models, laboratory and computational modelling, and collaboration with ocean modelling efforts.
My research has included a wide range of geophysical and environmental fluid dynamics, all involving experimental and theoretical studies of fluid flows relevant to: 1. modelling of ocean processes (e.g. ocean currents, fronts, convection and turbulent mixing); 2. modelling of convection in the Earth's mantle (e.g. upwelling plumes, sinking slabs and 'rollback' subduction); and 3. modelling of volcanic processes (particularly coupled flow, cooling and solidification). Common threads include the fundamental processes of turbulent mixing, thermal convection, multi-component convection, solidification, instability in density-stratified flows, and rotating flows. With expert technical assistance I developed a rotating table design for laboratory experiments and two of these tables are in operation in the geophysical fluid dynamics laboratory at ANU. I also proposed, designed and managed construction of the ANU's GFD laboratory, which was formally opened in 2000.
