Summary
I am interested in buoyancy-driven flows in natural, industrial and built environments, motivated by the important role this field of research has to play in understanding and responding to societal challenges concerning climate, energy and our environment.
I joined the Fluid Mechanics Section in the Department of Civil and Environmental Engineering at Imperial College London in 2016, following previous academic appointments in Australia and the UK. I hold BE and ME degrees (Auckland) and a PhD degree (Cambridge).
I am a member of the Editorial Board of Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences and an Associate Editor of Fluid Dynamics Research.
Areas of expertise:
Buoyancy-driven flows
Stratified turbulence and mixing
Convection
Turbulent plumes and jets
Flow energetics
Flows in the built environment
Ocean dynamics
