I have been working in molecular bacteriology during my PhD (Paris, France), Post Doc (NYC, USA) and in La Réunion as associate Professor. The models I have been working on include Bacillus subtilis, Wolbachia pipientis and pathogenic Leptospira. This latter species is an environmental zoonotic pathogen that I have been extensively studying for the last 5-7 years. The team I lead at UMR PIMIT/University of La Réunion has described Leptospira diversity and biological cycles in most of the islands of the western Indian Ocean, showing fairly distinct transmission chains in the different insular ecosystems, including either introduced species/lineages or endemic bacteria that have co-evolved with their mammalian rerservoirs. Beside pathogenic Leptospira, I am interested in developing innovative and environmental-friendly strategies for the control of the tiger mosquito Aedes albopictus, using my academic experience in Wolbachia endosymbiotic bacteria.
