My research focuses on the fluid dynamics of the ocean. I am particularly interested in ocean turbulence and mixing, ocean fronts and the surface boundary layer, and the impact of turbulence on micro-organisms. Recent work has uncovered a fascinating and poorly-understood collection of processes occurring at relatively small scales (<O(10km)) where the vertical motion is strong but stratification and the Earth's rotation are important factors. Since these motions are too small to be directly resolved by global ocean and climate models, understanding their impact on the structure and dynamics of the ocean is one of the most pressing topics in physical oceanography. Currently, I am studying the dynamics of upper ocean fronts, the turbulent boundary layer beneath melting ice shelves, stratified turbulence, and the influence of physical processes on biogeochemical dynamics. Please see my homepage (linked on the right) for more information.
