She is an ecologist with a broad interest in ecology and evolution, working on multitrophic interactions, parasitoid behaviour and especially parasitoid learning. Her research involves chemical, behavioural and molecular ecology of plants and insects in a multitrophic and community context. The research ranges from fundamental to strategic: from questions on the evolution of species traits and species interactions within communities to the strategic development of sustainable agro-ecosystems that are primarily based on the prevention of pests and diseases (life-support function of biodiversity).
