Insects are beautiful and vital for our ecosystem. Im interested in their ecology and evolution and how we can use this knowledge to improve sustainable agriculture and increase biodiversity


I have always been fascinated by insects. My research integrates fundamental and applied research to answer questions about species interactions and biological pest control.

In 2016 I started my PhD project at the University of Groningen where I investigated the potential of native natural enemies to adapt to exotic pest species and whether we can optimize natural enemies through selective breeding. In 2021 I became part of the "Smart Parasitoid" project where I investigate the behaviour and chemical ecology of parasitic wasps to understand how their foraging behaviour is influenced by their environment.

I like nature photography to capture the beauty and diversity of the nature around us

  • Smart natural enemies for sustainable pest control

    Project 2021–2024
    Parasitoids are key natural enemies that contribute to biological control of economically important pests in both agricultural and natural ecosystems. They are however not always efficient in finding the pest insect in the greenhouse because the (mass-)rearing conditions differ from the greenhouse environment in which they are released. This reduces parasitoid motivation and efficiency to search for herbivore insect pests.
