I am a microbial ecologist with a particular interest in host-microbe interactions between Eukaryotes and bacteria. My main research interests are: (i) host-microbiome interactions in arthropods and plants, (ii) genomics of nutritional endosymbionts of plant-sap feeding insects, and (iii) the ecology and evolution of insect-vectored plant pathogenic bacteria. For instance, we recently demonstrated that horizontal gene transfers played a key role in the evolution of phytopathogenicity in the mainly insect-associated genus Arsenophonus. Since my arrival at INRAE in 2022, my research focusses on the complex interactions between Xylella fastidiosa, its host plants, insect vector and their associated microbiomes.
