About me

Research interests: sexual selection theory, reproductive physiology, gamete evolution, reproductive and life-history trade-offs

My current research focuses on the effect of nutritional stress during development, how it affects energy investment in traits under pre- and postcopulatory sexual selection and how this translates into gene expression and protein synthesis. We conduct all our experiments with numerous genetically modified isogenic lines of Drosophila melanogaster, which are a uniquely powerful study system as they express either red- or green-glowing sperm. This enables us to develop original experimental design as well as control for genetic background.

Besides research in the lab, I am convinced that the importance of public outreach is greatly underestimated. This is why I regularly give lectures about biology to high-school and secondary-school students at the Life Science Zurich - Learning Center.

In my spare time, I also enjoy cycling, ski-touring and almost any kind of game or social activity.
