I am a Research Professor and highly-cited researcher in terrestrial systems modeling at the CICERO Centre for International Climate Research. in Oslo, Norway. My work focuses on improving the predictive capability of open-source models of the land surface.

I am most recognized for my work developing the Community Land Model (CLM), of which I am a co-chair, and the global demographic vegetation model FATES. I work with the Norwegian Earth System Model (NorESM), as well as a global network of collaborators on projects across terrestrial system science.
