Research thematics

My PhD project aims at deciphering Synechococcus ecology by studying the ecotypic variability of stress response in this marine picocyanobacterial genus. More specifically, I focus both on the geographic distribution of Synechococcus clades and on the genomic and physiological diversity of a range of strains.


Previous Research Experience

  • 2014 - 4 months Master's degree internship in the Tucson Marine Phage Lab (Sullivan Lab, now located at Ohio University).
    Transcriptomic and proteomic response of two closely related strains of a marine bacterium (C. baltica) to the infection by the same bacteriophage, the two infections having different outcomes.
     
  • 2013 - 4 months Master's degree internship in the MaPP (Marine Phototrohic Prokaryotes) group at the Station Biologique de Roscoff.
    Genetic regulation and the geographic distribution of "type 4 chromatic acclimation" (the ability to change pigmentation depending on the light quality) in Synechococcus.
     
  • 2012 - 4 months Master's degree internship in the Rhizosphere group at University Lyon 1 (UMR 5557).
    Plant-Growth Promoting Effect of the rhizobacterium Azospirillum lipoferum through genetic engineering.
     
  • 2011 - 2 months internship as undergraduate in the Plant Reproduction and Develpment Lab (ENS Lyon).
    Role of the "retromer" complex in root growth of the model plant Arabidopsis thaliana.


Education

  • 2014 - Current: PhD student at the Station Biologique de Roscoff, focusing on the ecology of Synechococcus.
  • 2011-2012 and 2013-2014: Master's degree: Master Biosciences, ENS Lyon
