I am an early career researcher working on microbial diversity, interactions and dynamics in marine coastal ecosystems. After completing a Ph.D. on diatom-parasite interactions in the Western English Channel, I am currently carrying out a project on phytoplankton assemblages and their seasonal dynamics in harbor areas.

RESEARCH INTERESTS

  • Host-parasite interactions
  • Virus ecology
  • Microbial diversity
  • Marine ecosystem dynamics

 

Research experiences

  • 2019 (6 months): PhytoPort project. EDYCO Team, Station Biologique de Roscoff
    Sampling and analyses of microalgae in harbor systems
     
  • 2018 (3 years): Ph.D. Thesis "Control of diatom blooms by parasites in the Western English Channel". DIPO Team, Station Biologique de Roscoff
    This PhD project aimed at identifying the parasitic network involved in the control of dominant diatoms in the Western English Channel. Combining field sampling, isolation, characterization and in situ approaches, we revealed an unsuspected diversity of parasites that infect diverse diatoms, with at least three types of parasites belonging to distinct lineages: viruses, a eukaryotic parasite and algicidal bacteria.
