In my research, I am to understand the effects of global environmental changes and uncertainties on the relationship between biodiversity, ecosystem functions, and agricultural production and crop quality.

I was a lead author of the IPBES report on pollinators and of the ESAC report on the potential effects of Neonicotinoids and agro-ecosystem services.

I am the vice president of the German Ecological Society GfÖ and I advise policy at the state of Baden-Württemberg and at the national level. Sometimes I am struggling to find a good balance between research, teaching, leading, administrative work, and science communication.
