Currently supported by ARC Future Fellowship ("The dynamics of convection - insights for ocean and climate physics and for solar thermal energy system design", 2011-2015)
My research interests lie broadly in buoyancy-driven flows, spanning fundamental processes that include convection, instability and mixing, wave dynamics and the interaction of flow with topography. I make use of laboratory experiments and theoretical models to help understand these processes and thus the geophysical, environmental and engineering flows to which they are relevant.
