I am a research professor, leader of the Ocean Biogeochemistry research theme at NORCE Climate and a member of the Bjerknes Centre for Climate Research. The objective of my research is to apply Earth system models and observations to advance our understanding and prediction of anthropogenic climate change; to model large scale ocean biogeochemical cycle and its interactions and feedback to the climate system from interannual to centennial time scales; to quantify the dominant internal climate variability and elucidating how they are affected by external forcings,such as carbon dioxide, volcanic eruptions, and large scale geoengineering; to determine and attribute sources of uncertainties leading to the large spread in climate models; to use observations and various statistical metrics to constraint and characterize model uncertainties and minimize projection errors. I am part of the Norwegian Earth System Model consortium and coordinate the development and maintenance of the ocean carbon cycle component.
