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).

Congratulations to Manu, for his publication in Communications Biology! Finally, one of the stories on soil bacteria in the famous alginate beads is out, showing the importance of interspecific effects on growth of soil bacteria communities. And read 'behind the paper'.
