Profile

Biography

1976-1979: PhD in geophysical fluid dynamics, ANU (on double-diffusive, or thermohaline, convection)

1979-1981: Postdoc, Department of Applied Mathematics and Theoretical Physics, University of Cambridge, UK (on rotating stratified flows and the instability of ocean currents)

1982: Research Associate, Institute of Mechanics, University of Grenoble and CNRS, France

1983-present: RSES, ANU.

Elected Fellow of the American Physical Society 2014, Inaugual Fellow of the Australasian Fluid Mechanics Society in 2011, Fellow of the Australian Academy of Science 2001, Fellow of the American Geophysical Union in 2001, Fellow of the Australian Institute of Physics in 1991.

Awarded the Centenary Medal for service to science in Australia in 2001, Japan Society for the promotion of Science Invitation Fellowship in 1997 (3 months at the University of Hakkaido), Priestley Medal of the Australian Meteorological and Oceanographic Society in 1991, Postdoctoral Fellowship at the Woods Hole Oceanographic Institute Geophysical Fluid Dynamics Summer Program in 1980.

Oversaw the design and 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 for 6 months in 2006 and head of the Earth Physics section of the School 2006-2010.

Associate Editor of the Journal of Fluid Mechanics, published by Cambridge University Press (submit articles to me, or any of the Associate Editors, online through ScholarOne at http://mc.manuscriptcentral.com/jfm).

Research

Research interests

My present research is on the fundamental physics of convection, including the roles of potential and kinetic energy. I am also studying the dependence of turbulent mixing on the kind of flow, whether convection or stably stratified flow, and the dynamics of the global ocean overturning circulation. The latter contributes to transport of heat from low to high latitudes in the earth's climate system and sets the deep ocean stratification.

My research has included experimental and theoretical studies of ocean currents and density fronts, of upwelling plumes and sinking lthospheric slabs in the earth's  mantle, and  of volcanic flows (particularly gravity-driven flows with coupled cooling and solidification).
