Research

Plant community dynamics: In my research I seek understanding of the dynamics in species rich plant communities such as tropical forests or semi-natural grassland communities. I am interested in the fundamental questions how species and functional diversity are generated and maintained in these ecosystems. With respect to applied science, I strive for improved models to predict the response of plant communities to environmental drivers, such as fragmentation, land use and climate.

Model-data integration: To address these questions I develop and apply spatial and dynamic simulation models, e.g. individual-based models or metacommunity models. For model validation and predictions I am interested in statistical methods to combine simulation models with empirical data, e.g. Bayesian analysis or pattern oriented modelling.

Trait-based plant ecology: I consider the focus on plant functional traits as a promising approach to acquire general knowledge that is not restricted to specific locations and plant assemblages. I think that trait-based community models facilitate the incorporation of ecological and physiological processes and foster the mechanistic understanding of species coexistence as well as of species responses to environmental drivers.
