I study Earth system variability and predictability on seasonal to multidecadal timescales. Broadly speaking, I use Earth system models to explore the mechanisms of ocean and coupled climate variability that help to explain past, and potentially anticipate future, regional environmental change. General topics that I have worked on include: the causes and consequences of annual to multidecadal variability in the Atlantic Ocean, the origins and pathways of initial condition memory in seasonal to decadal prediction, model process representation and associated implications for prediction, high resolution modelling, and prediction system design and evaluation. I am interested in developing seasonal to decadal forecasting systems with and for the broad community engaged in predictability research. My current projects focus on advancing understanding and predictive capacity related to multidecadal climate over the US, Southern Ocean processes, the Atlantic meridional overturning circulation, and coastal sea level.
