Research interest:

Broadly viewed, my main research interests are centered on global change and its consequences. The ongoing man-made changes in components of the Earth's biodiversity, ecosystems and their functions cause a strong potential to alter ecosystem properties and the goods and services they provide to humanity. Currently I am dealing with the impacts of biological invasions on species interaction, community composition and ecosystem functioning.


  • Feedback between plants and soil biota in invaded ruderal plant communities



Displayed are the biotic interactions of an introduced invasive plant species and a native competitor. Below- and aboveground interactions may affect each with different extent, contributing to plant's overall performance and its competitive ability within a community.


  • Further, I investigate whether certain plant functional traits (e.g. nutrient uptake strategy, growth form, floral display) within plant communities and functional diversity in general affect community resistance to invasion.
