Scientific Interests
I am interested in the interactions of metals with living systems. I aim at developing chemical tools to dissect these interactions at the molecular level, in the case of endogenous metals like Cu or Ni, or in the case of exogenous metals like lanthanides and actinides.

Research and professional experience
    Since October 2020: researcher at CEA-Grenoble, France.
    2016-2020: Post-doctoral position, laboratory of Prof. Dorothea Fiedler (FMP-Berlin, Germany)
topic: Chemical Biology tools to investigate the role of inositol pyrophosphates
    2012-2015: PhD in chemistry, supervised by Prof. Clotilde Policar and Dr. Nicolas Delsuc (ENS Paris, France)
topic: Rhenium tricarbonyl complexes for the labelling and multimodal imaging of peptides and proteins

Education
2008-2012: Diploma of Chemistry (minor: Biology) of Ecole Normale Supérieure (Paris, France)
2011: Master’s degree in Molecular and Cell Biology (Cell Systems Biology) (Université Pierre et Marie Curie, Paris, France)
2009: Bachelor’s degree in Chemistry (Université Pierre et Marie Curie, Paris, France)

Scientific activities
Member of the French Chemical Society
Member of the Society of Bio-Inorganic Chemistry
Member of Arcane Scientific Advisory Board
Member of the FrenchBIC network
