My primary interest is the environment, the quality of our living resources and the ways that bacteria can help to manage and degrade human wastes and restore environmental health. Consequently, I am very interested in genetic adaptation processes in bacteria, the mechanisms by which they deal with toxic substances, how they react to pollution in general and how we can apply microbial processes in a useful way (like bacterial bioreporters, bioremediation, microbiome engineering).

We are looking for an enthusiastic postdoctoral worker interested in studying microbial species-species interactions in mouse gut communities using high throughput bead technology. This collaborative project will be carried out within the newly started NCCR Microbiomes with the group of Sigi Hapfelmeier at the University of Bern. To apply, please contact me or submit your application directly on the UNIL recruitment site.
