I am an active scientific researcher with interests in theoretical and computational fluid dynamics.

My main research interests are in:   

  • Hydrodynamic stability  
  • Vorticity-based numerical methods and formulations
  • Fluid-structure interaction
  • Rotating and oscillatory boundary layers

Much of my time is spent conducting and supervising research. But I also very much enjoy teaching applied mathematics, and communicating my enthusiasm for the subject to undergraduate students!

Research achievements

One of the main achievements of my research to date has been the demonstration that, at least in theory, compliant surfaces may be designed so as to delay the transition between laminar and turbulent flow in a boundary layer to indefinitely large Reynolds numbers.

Another significant achievement was the derivation of a new velocity-vorticity formulation of the Navier-Stokes equations. This new formulation has proved to be particularly suitable for simulating the evolution and control of three-dimensional disturbances in boundary layers.

I have also shown that the absolute instability that is found in a family of rotating boundary layers does not give rise to a global form of linear instabilty in anything like the manner that was predicted by other researchers. The connection between the local and global behaviour has turned out to be far more subtle and interesting than had been anticipated.

Most recently, along with my research collaborators, I have discovered a completely unexpected family-tree structure in the spatial-temporal evolution of disturbances that are excited in oscillatory boundary layers.
