Biography: 

I study geophysical fluid dynamics, mainly related to oceanic and atmospheric flows. My approach is to combine theory with numerical modelling, generally in idealized settings. Specific topics include air-sea interaction, ocean turbulence on a variety of scales, and Arctic oceanography. Two of my most influential results have i) shown that an ocean current influence on air-sea momentum fluxes accounts for about 30% of the total removal of kinetic energy from the ocean's geostrophic circulation, ii) that zonal transport of the Antarctic Circumpolar Current (the world's strongest) is insensitive to the strength of wind forcing (due to a process known as eddy saturation). In recent years, I have taken an interest in Arctic circulation and the influence of sea ice. I would like to get more involved with environmental fluid mechanics (e.g, river and hydrological flows) as these appeal both to my general interest in geophysical turbulence and connect naturally with coastal and estaurine oceanography.
