The aim of my research is to understand the fluid dynamics of the global ocean circulation and its impact on climate. We employ a wide range of tools including idealised mathematical models (solved with pen and paper), idealised numerical models (run on desktop computers), state-of-the art ocean circulation models (run on national supercomputers) and analysis of observations. Areas of current research include: dynamics of the Antarctic Circumpolar Current/Southern Ocean and impacts on global stratification, heat uptake and the carbon cycle; dynamics of the Atlantic meridional overturning circulation and its response to surface forcing; interactions between ocean eddies and the large-scale circulation; impact of variable bottom topography on ocean circulation; dynamics of western boundary currents, such as the Gulf Stream, and their separation. I encourage my students to develop a broad interest in dynamical oceanography and am interested in supervising projects on any of these or related topics.
