After a Master degree in Agronomy with an internship on Camel antibodies at the Pasteur Institute of Paris in 2002, Marie did a PhD in molecular immunology in Marseille (France), to build dynamical models of V(D)J recombination and allelic exclusion. She then did a multidisciplinary post-doctorate in Lisbon-Oeiras (Portugal) on illegitimate DNA rearrangements in T-lymphocytes to determine the Recombination Activating Genes off-targets DNA sequence and epigenetic features. She joined the Immunogenetics Group as Project Coordinator in 2019 to work on FMDV specific antibody discovery, as part as a Bill and Melinda Gates Fundation project. She is now Interim Group Leader. Her interests lay in antigen-specific antibody discovery in livestock and cattle antibody repertoire diversification.
