Research interests

My research focuses on understanding interactions between the environment and multiple biogeochemical cycles. I use mathematical tools, ecosystem models, and measurements to improve our predictions about the responses and feedbacks between climate and terrestrial ecosystems. I am particularly interested in tropical forests and their interactions with the climate system.

I lead an independent research group on Theoretical Ecosystem Ecology funded by the German Science Foundation through the Emmy Noether Program. Our group is focused on producing synthesis of ecosystem models and studying nonlinearities in biogeochemical cycling.
