My current research is concerned with the basin-scale ocean circulation and air-sea interaction in the Arctic-Atlantic region, and whether associated climate and sea ice variations are predictable on interannual-to-decadal time scales. Previous work has been on regional oceanography and air-sea interaction in both the Arctic and Antarctic, combining observations and fieldwork with numerical models (climate models, regional ice-ocean models and idealized models).
