My current research is at the crossroads of community and ecosystem ecology. I aim at understanding how terrestrial and aquatic biodiversity regulates energy and material flows within and across ecosystems. I am interested in the following questions: What do species do in ecosystems? Does intraspecific trait variation matter for ecosystem functioning? How and to what extent trophic and non-trophic interactions regulate ecosystem functions? Whether and how biodiversity dynamics alters ecosystem functioning? What are the consequences of the ongoing biodiversity loss on Nature's value?

My research is based on field surveys, experiments conducted at realistic scales, and meta-analyses. I strive to incorporate the complexity of real ecosystems into my research, to address mechanistic issues and to seek for general patterns across regions. I have worked with a variety of biota (fish, macroinverterbrates, aquatic hyphomycetes, benthic algae, riparian plants) which are pivotal in food webs.
