I am interested broadly in fluid mechanics for sustainability. My focus is on buoyancy-driven flows in natural, industrial and built environments, motivated by the important role that this field of research has to play in understanding and responding to overarching societal challenges concerning climate, energy and our environment. If you are interested in PhD opportunities in these areas, please contact me by email.

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 and heat transfer
  • 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
