My primary research interest is to understand the interactions between vegetation, atmosphere and humans. Therefore, I develop and apply different modelling approaches, particularly process-based dynamic vegetation models (DGVMs), to simulate ecosystem dynamics, biogeochemical cycles, and diversity. Vegetation models are coupled with land use models to help us understand how climate change and land-use influence ecosystems, diversity and ecosystem services, and to help develop strategies for the sustainable use of natural resources.

My research interests involve the field of climate-vegetation interactions and human influences. This matches well with the BMBF-funded SPACES project EMSAfrica (Ecosystem Management Support for Climate Change in Southern Africa). EMSAfrica focuses on the effects of natural disturbances, such as the impacts of land-use and climate change on the structure and functioning of South African terrestrial ecosystems. It also focuses on the production of information relevant to ecosystem management in the region. Within the scope of this project I am working with the dynamic vegetation models (DVMs) aDGVM and aDGVM2 with a focus on Southern African vegetation changes. By using DVMs, I would like to detect changes in ecosystems and identify areas that require special attention in ecosystem management. Thus, I can contribute to protecting and maintaining biodiversity in vulnerable ecosystems.
