Research summary

Although considerable progress has been made over the past decades in understanding and quantifying carbon cycle-climate feedbacks, many aspects of the global carbon cycle are still not well understood and, thus, very poorly resolved in Earth system models. This is particular true for the fate of (organic) carbon as it cycles through the Earth system and across its interfaces (such as the sediment-water, the ice-ocean or the land-ocean interface). Advancing our quantitative, mechanistic understanding of carbon (and associated inorganic and nutrient) cycling; using this understanding to improve Earth System Models and applying the improved models to assess the role of carbon cycle-climate feedbacks for past and future climate change is the foundation of my ongoing research.
