Research focus


Since my early studies, I am interested in the chemical processes underlying the interaction of phototrophic organisms and their environment. I specifically focus on the use of analytical methods to identify and locate metabolites involved in these processes. With my background in experimental ecology and analytical chemistry, I support the group of MIE, establishing an analytical platform (LC-QqQ, LC-qToF, GC-QqQ) to investigate the multitrophic interactions associated with plants on a chemical level. As head of the laboratory I also train and support students and researchers as well as coordinate the experimental resources of the MIE group.
