Research interests

My research interests are broad and revolve around the ecology and evolution of environmental and pathogenic bacteria in relation to their animal or human hosts. I study different levels of these host-pathogen/host-bacterial interactions, mainly with a microbial population biology angle: how the ecology and environment can impact on bacterial and microbial population evolution, how pathogens emerge from background asymptomatic carried populations, and how microbes jump and transmit between various hosts. For example, I try to understand the impact of host factors (ecology, physiology or immunity) on the evolution and adaptation of the bacterial species they carry. Recently, I have been interested in how intensive agriculture and the domestication of livestock could have an impact on the microbes/pathogens they carry, on their evolution, ecology and virulence to humans and animals.

My work relies on a combination of field sampling, in vitro and in vivo laboratory work, genome sequencing and bioinformatic analyses. In the past few years, I have focused on the population genomics and ecology of bacteria, including the zoonotic pathogen Campylobacter and Escherichia coli populations, but also nosocomial pathogens from Staphylococcus, and insect-associated Bacillus thuringiensis.
