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 Gaitan and Nicolas for their new publication, uncovering the bimodal pattern of manganese oxidase expression in stationary phase Pseudomonas putida cells. Not yet the 'why' for manganese oxidation but at least the 'when'! And a great outcome of a wonderful collaboration with the group of Jasquelin Pena at UC Davis.

Congratulations to Tania, Isaline and Xavier, with help of Manupriyam, Elvire and Helena, for their work on a new method to infer interactions between bacteria from time-lapse microcolony measurements! Just published and online downloadable for everyone!

Triple Hurrah, first to Tania and Senka for successfully and brilliantly passing their PhD exams (bravo, Tania and Senka!), and to Maxime for the appearance of his first paper on Habitat fragmentation in picoliter droplets showing the effects of phenotypic variation of founder cells of species pairs on their reproductive success (aka the picoliter droplet story). Bravo Maxime, Isaline and all the other collaborators.

Congratulations to Senka, Manupriyam and Marian, with help of Vladimir and Nico, for their combined forces to show the role of nutrient niche availability and metabolite facilitation that control proliferation of bacterial inoculants into (contaminated) soils! A special thanks to Guillem, Hans and Shini for collaborating on the metatranscriptomics analysis. A milestone for our lab!
