About us

We study the roles of secondary metabolites in interactions among fungi, plants and arthropods. Most of our projects focus on mycotoxins and ecological chemistry but we also investigate selected aspects of plant diseases caused by vascular pathogens and Fusarium species. Furthermore, we provide services in analytical chemistry and participate on applied research projects on mycotoxins and food safety.
