Research Interests

In our laboratory we are studying the mechanism of cross-resistance between heavy metals and antibiotics. Molecular bacteriology and biochemistry methods are used to monitor the effect of Zn, Cd, Co and Cu on the bacterium Pseudomonas aeruginosa. Our group interacts strongly with the section of pharmaceutical sciences and the medical faculty for both teaching activities and research. We are also interested in problems related to wound infections. The laboratory offers various services, expertise and microbiological analysis to the community, particularly in the context of the search for new antimicrobial molecules (see PAM). The team manages various communication missions and services to schools and the general public in the field of life sciences (see BiOutils; services to the city).
