Biodiversity in research and for society

My scientific mission is to elucidate how biodiversity affects ecosystem functioning. My research focuses on interactions between plant roots and soil-borne fungi at the community level and has contributed to paradigm shifts in the understanding of resource complementarity and functional trait ecology in grassland systems. Currently I focus on understanding the mechanisms underpinning the biodiversity effects on belowground disease risk. Overcoming this gap is essential for transforming agricultural systems from monocultures that are sensitive to disease outbreaks to diverse cropping systems that are intrinsically resilient to pathogens. The importance of my work is evidenced by the fact that I am recognised as a highly cited scientist (i.e. belonging to top 1% best cited scientists of the world) in 2021 and 2022.  

Nearly two decades of scientific research have convinced me that biodiversity is a safety net for our planet. However, biodiversity loss is unprecedented and threatening the planet, ecosystems and people. This is why I initiated and lead the Wageningen Biodiversity Initiative (WBI). In this capacity, I develop and lead research programmes related to biodiversity in the food system and nature-inclusive society, 2) guide policy making by synthesising scientific insights and discuss these with policymakers and politicians (e.g. the European soil health law https://www.wur.nl/en/dossiers/file/soil-health-2.htm); and 3) speak to the media to create public awareness around the importance of biodiversity for planetary and human health (see picture: speaking about biodiversity on national TV).
