Environmental and Evolutionary Microbiology

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).

Happy to say that after a lot of collaborative efforts, our work characterizing the transfer competence regulon of ICEclc was published in PLOS Genetics. Thank you, Sandra, Andrea, Roxane, Nico, Vladimir, François and Veronica! This was an amazing journey with lots of images, time-lapses, qqplots, RNAseq and clonings; and a fascinating discovery on the life of mobile DNAs.

First publication within the NCCR Microbiomes studying how complex soil microbiomes can be grown in standardized soil systems, either from 21 individual soil isolates, or from washed natural topsoil communities. Great collaboration with Christian von Mering and Janko Tackmann at the University of Zürich.
