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 Diogo, Artur, Shantanu, Vladimir and Aurélie, for their new publication on ribose-binding-protein engineering, appearing tomorrow:

Thanks to their continued efforts, we have been able to shed ourselves of some of the shadows cast by previous irreproducible 'high-impact' work on ribose-binding-protein engineering.

We are happy to welcome Cédric Schneider, who is joing our lab for his civil service, working on biosensor development,

and to Samuel Aubert, first step Master student in Biology, who is working on the conjugative system of ICEclc.

Congratulations to Roxane and François for their beautiful work showing how ICEclc is replicated in individual cells preparing for conjugative transfer.

This is the last week for Maxime, finishing his Master's project on the design and engineering of phenol-responsive ribose-binding protein mutants, and for Nora, who helped Birge on the lake water  communities project. Thank you so much, both of you, for the wonderful time and your endless energy! We will miss you. All the best for your future studies and careers.

Welcome to Andrea, our new PhD student working on the ICE project

and to Senka and Caroline, two new master students, who will start their projects mid-February.
