Caroline Müller has been full professor for Chemical Ecology at Bielefeld University, Germany, since 2007. She received her PhD from Free University of Berlin in 1999. She then spent a year as postdoc at Boyce Thompson Institute Ithaca, USA, and three years at Leiden University, The Netherlands. In 2004, she became independent group leader for Chemical Ecology at Würzburg University, Germany. Caroline is fascinated by the manifold functions of natural products in plant-insect interactions and their chemodiversity. She has elucidated central aspects of how natural products direct insects to their host plants and initiate feeding, how insects detoxify these compounds and use them for their own defense against predators, and which role they play in invasions. She also contributed significantly to revealing how various aspects of global change, including pollutants such as heavy metals, microplastics and pesticides as well as climate change factors, affect plants and their interaction partners.
