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).

We're very happy that our concerted review on microbiome engineering, collectively written by members of the NCCR Microbiomes, has now been published. We hope this will be widely interesting for researchers in the field!
