My main research interest is to understand the distribution of life on earth (e.g. species, biodiversity, vegetation types, ecosystems) through space and time. I am particularly interested in interactions between climate and the terrestrial biosphere. This includes potential impacts of climate change on species, ecosystems and associated ecosystem services, as well as the role of the biosphere in the earth climate system (e.g. carbon and water cycling). Methodologically, vegetation and ecosystem modelling at local to global scales has been at the core of my work.

Fields of interest
I am fascinated by interactions between organisms, especially if they are mutually beneficial for both partners*. To understand the structure and function of ecological networks, I study species interactions in ecological communities along environmental gradients and across large spatial scales. My research uses trait-based approaches in combination with field studies, experiments and simulation models to predict the impacts of climate and land-use change on ecosystem functions and services. (*I usually become enthusiastic if one of the interaction partners has wings and a beak.)
