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 also Director of Education for the Energy Futures Lab at Imperial.
Areas of expertise:
Stratified turbulence and mixing
Turbulent plumes and jets
