Research Interests:
My research interests centre on physical processes
governing the ocean and climate. This includes:
Ocean Eddies:
Ocean eddies are small scale (10-100km) vortices which occur in all regions of the ocean.
Despite their small size, they can have significant impacts on large scale ocean circulation -- and climate.

Ocean Straits:
Flow through ocean straits (such as the Straits of Gibraltar) are energetic and nonlinear, producing strong turbulence and mixing.

Glacial Climates:
One of the outstanding puzzles in paleoclimatology is to determine the cause of ice ages.

Shear Instability:
Flow in a density stratified can be unstable because of velocity gradients in the fluid.
The resulting "shear instability" produces vortices (such as the Kelvin-Helmholtz billow shown here) and turbulence.
