My primary research interest concerns the splendid array of compounds that are made by plants and the underlying molecular and biochemical basis of their synthesis. Our research focuses on natural products that are of medicinal, industrial or pharmacological relevance and on specialized metabolites that help plants cope with their dynamic environment. We employ a diverse set of approaches throughout these investigations that rely on genomic, classical biochemical, and molecular biology resources. We also work closely with collaborators in various fields such as organic chemistry, food science, neurobiology, and ecology with the overall goal to shed light on the processes that operate at the interface of plant primary and secondary metabolism.
