I am a Research Professor in terrestrial systems modeling at the CICERO Centre for International Climate Research. Oslo, Norway.

My work focuses on improving the predictive capability of open source coupled Earth system models, with particular emphasis on land–biosphere processes and their role in carbon-cycle and climate feedbacks.

I am the external co-chair of the Community Land Model (CLM) and the FATES vegetation model and I work with the Norwegian Earth System Model NorESM.
