RESEARCH INTERESTS: The aim of my scientific research is to bring an evolutionary perspective to the study of symbiosis, through an understanding of the molecular interactions between partners. I'm currently studying processes and mechanisms associated with rapid evolution of the fly/Wolbachia association in response to stresses (oxidative stress, viral infection).

CURRENT POSITION (since 2014): Permanent research position at the CNRS (Centre National de la Recherche Scientifique, section 27). Laboratory of Biometry and Evolutionary Biology. UMR CNRS 5558, University of Lyon (Lyon 1).


2010-14 Postdoc University Madison, WI, USA. “Establishment and maintenance of the squid/vibrio symbiosis”. Advisor: Pr. M. McFall-Ngai (Medical, Microbiology & Immunology department).

Hooked on Wolbachia

This very nice paper by Martinez et al. [1] provides further evidence, if further evidence was needed, of the extent to which heritable microorganisms run the evolutionary show.
Wolbachia is an ubiquitous endosymbiont of arthropods who has been recently shown to protect its hosts against viral infections. Here, Martinez et al. are able to show that this multifaceted heritable symbiont weakens selective pressures induced by viruses on host immune genes. In a series of very elegant experim...
