I am interested broadly in the fluid mechanics of sustainability. My focus is on 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 overarching 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
- Turbulent plumes and jets
- Flow energetics
- Flows in the built environment
- Ocean dynamics
with applications including:
- environment quality and air quality in indoor and outdoor settings
- efficient energy use (e.g. conditioning of buildings)
- solar and marine renewable energy systems
- circulation of oceans and lakes
