Plant-microbe Interactions, Phytopathology, Microbiology

Understanding how organisms communicate to establish mutualistic interactions is our key research interest. We focus on plant-associated bacteria and study their ability to emit volatile compounds that protect plants against diseases. We work with well-established model plants like Arabidopsis thaliana, as well as with crops of agricultural relevance such as potato, tomato and grapevine. Our research spans from fundamental understanding of beneficial plant-microbe interactions to the application of the acquired knowledge for sustainable crop protection.
