To study the evolutionnary potential of microorganisms, I have decided to study the various way in which their genome can evolve. I am interested in the way diversity is produced, how mutation rate and recombination rate are variable and can influence bacterial evolution.I am interested in the way genes are acquired and the relative contribution of acquired genes versus house keeping gene in the adaptation to some specific niches. I am interested in the way interactions whithin a genome are building up and what are their consequences on microbial evolution.
In order to progress in the understanding of microbial genome evolution, I use several approaches : population genetics theory and the simulation of evolving populations with computers, molecular evolution : the study of DNA sequences and experimental evolution : the evolution in the lab of viruses and bacteria.
