I originally graduated with a BSc in Marine Sciences from the University of Québec at Rimouski in Canada, with a year abroad studying Tropical Marine Ecology and Ecosystems Management at the University of Antilles and Guyana in Guadeloupe. Following this, I completed an MSc in Development, Interaction and Evolution of the living at the University of Perpignan in France. During this time, I worked at the CARMABI Foundation in Curaçao where I undertook research in coral reef ecology. My research concerned the cascading effects of key reef-builders decline on associated fish and coral communities, in addition to leading another project on the effects of nursery habitats on coral reef fish assemblages and grazing pressure. Afterwards, I moved to French Polynesia and worked at the CRIOBE lab to complete my PhD in Biodiversity, Genetics and Evolution. The overarching goal of my PhD project was to evaluate the benefits of asexual versus sexual reproduction, together with phenotypic plasticity, in the population maintenance of fire corals. After completing my PhD I pursued my research as a Postdoctoral Research Fellow (LabEx CORAIL) at the University of La Réunion with an interest into the functional complexity of microbial communities associated with fire corals. My research concerned the co-variation of host genotypes and microbial communities across reef habitats (in situ). I used metabarcoding techniques to assess whether microbial communities change among clone mates that are naturally exposed to variable environments. In March 2018 I joined the CRIOBE where I pursue my research on the microbiome as a CNRS Postdoctoral Researcher, working on the black-lipped pearl oyster Pinctada margaritifera. I rely on ecological approaches, combined with classical population genetics and genomics, to provide new insights into holobiont structure and function.
Since 1970, the pearl industry of P. margaritifera has become a major economic resource in French Polynesia, producing up to 8000 kg of pearls per year. Pearl farming has dropped considerably over the past decade, mainly due to overproduction at the expense of pearl quality. Although recent studies have investigated the genome, transcriptome and phenome associated with pearl quality in P. margaritifera, there is no information on its microbiome. In this context, my work focus on the bacterial dynamics throughout the grafting process to explore the respective contribution from the donor and recipient oyster genomes to the microbiome structure. This work will also provide the very first description of P. margaritifera-associated bacteria that can then be targeted in functional studies to improve pearl quality.
