Research interests:
I am mainly working on basin-scale ocean circulation and air-sea interaction in the Arctic-Atlantic region, and how variable ocean circulation on interannual to multidecadal time scales impacts climate variability. I am currently leading a project (ArMOC) where we want to understand how ocean circulation in the Arctic could change in a warming climate.
