Research field
    Despite the importance of microbial communities for the functioning of ecosystems, little is known about their diversity and functioning and how it varies in time and space. In addition mechanisms shaping this diversity and the interactions between the various members of these communities is poorly known. This lake of knowledge is especially true for the eukaryotic component and their associated viruses, both in marine and continental environments. In this context, I am interested in the diversity, evolution and ecology of the eukaryotic component of planktonic communities and their viruses. I seek answers to questions such as: What is the within-species genetics diversity in planktonic organisms? What shapes this variation? What is the diversity of eukaryotic virus in oceans and what are their ecological roles? -Thematic: Population genomics (intraspecific diversity of eukaryotic plankton) – Environmental genomics (diversity, evolution and ecological role of eukaryotic viruses) – Evolutionary genomic (Evolution of duplicated genes) -Keywords: evolution, diversity, genomic, plankton, viruses.
Current research
  1. Assessing the diversity and deciphering the roles of marine eukaryotic viruses in epipelagic oceans using environmental genomics and contextual data.
  2. Understanding the evolutionary history of large nucleocytoplasmic DNA viruses via genomic analysis of in-lab isolated viruses.
  3. Study of standing genomic variation in phytoplankton species such as Ostreococcus tauri or Triparma laevis: what mechanisms shape this variation and how this variation channels future evolutionary changes?
  4. During my postdoc I worked on “evolution by gene duplication” in Meloidogyne (nematodes). I continue to work on this thematic in land plants where I try to understand the processes that led to functional diversification of their phosphatidylinositol phosphate 5-kinases.
