Main Research Interests

My research concerns evolutionary biology of host-symbiont interactions. I aim at addressing several issues ranging from host adaptation to symbionts, to symbiont-mediated ecologically important traits, such as defense against parasites or pesticides resistance. Arthropods are particularly suitable models to study these interactions, as they frequently host vertically-transmitted bacteria, which spread using two main strategies: mutualism, in which symbionts directly benefit to their host; and reproductive parasitism, in which symbionts manipulate the reproduction of their host to their own advantage, often at the expense of males (ie evolutionary dead-ends for maternally inherited bacteria). Presently, I am studying the interactions between the endosymbiontic bacterium Wolbachia and its host, the spider mite Tetranychus urticae.

Ongoing Projects:

2013-2016: Postdoctoral fellowship. Evolution of sex allocation in Tetranychus urticae, a major crop pest (under the supervision of Sara Magalhães and in collaboration with Isabelle Olivieri at the University of Montpellier; FCT_ANR grant). My postdoctoral project mainly aims at following the adaptation of spider mites to the endosymbiotic sex-ratio distorter bacteria Wolbachia, as well as unravelling the mechanistic basis of Wolbachia sex-ratio manipulation of their host.
