I am interested in chemically mediated interactions between organisms like host finding and sexual communication. My special interest is to understand the importance of microbial signals on plant-insect interactions.
Chemical ecology provides a great basis to develop sustainable insect pest control methods for example by disrupting insect behavior.
Currently, I link basic research on the model insect Drosophila melanogaster with applied aspects to control the fruit pest Drosophila suzukii.
I am the subject editor for the Journal of Pest Science.


2001 Diploma in Biology, University of Freiburg, Germany.
2006 Dr sc. nat., University of Zürich, Switzerland.
Since 2006 I work on insect sensory physiology and behavior and aim to combine basic research with the development of sustainable control methods for horticultural and agricultural pest insects.
My main expertise is on chemical ecology, plant protection, entomology, microbiology, behavioral assays.
