I am interested in maximizing functional agrobiodiversity in agroecosystems to enhance the delivery of regulating ecosystem services towards favouring high and stable productivity. I design and conduct original field-based experiments integrating various crop and non-crop species (intercropping, companion planting, wildflower strips at margins), study the complex interactions at play, and evaluate the resulting multifunctional performances. Especially, I have been focusing on strengthening agroecological crop protection, by reducing risks of infestation by insect pests, weeds and pathogen, and favoring conservation biological control by natural enemies (predators, parasitoids). I am an Associate Editor for the journal Arthropod-Plant Interactions (Springer Nature).
