We are interested in the ocean's role in the climate of the Earth. The ocean plays a determining role in the variability of the climate system on inter-annual to millennial timescales. We use global observations and a hierarchy of ocean models together with advanced computational and mathematical techniques to study the ocean. Our current research is directed in three broad areas:

1. the surface-to-surface transport and ventilation of ocean water masses
2. inter-annual to decadal variability of the ocean's wind-driven circulation
3. global ocean biogeochemical cycles
