About

Research

My research is focussed on the experimental measurement of turbulent flows.  Some topics that I am actively pursuing are:

  • The generation of bespoke turbulence at high Reynolds numbers.
  • The interaction of turbulence at a gas-liquid (air-sea) interface.
  • The impact of turbulence on various geometries (e.g., airfoils, buildings, wind turbines).
  • The influence of free-stream turbulence on a turbulent boundary layer.
  • Wind-assisted propulsion.
