I'm an Associate Professor in the Department of Applied Mathematics at the University of Waterloo. My research area is geophysical turbulence. Broadly defined, turbulence is chaotic fluid flow with interactions across a wide range of length scales. In the atmosphere and ocean, the range of scales is huge: from millimetres to thousands of kilometres. Geophysical turbulence is influenced by buoyancy, the rotation of the Earth, and phase changes of water, and my research examines all of these effects.
