Bruno Lamas was recruited to INRA in 2017 after having been post-doctoral fellows at the INRA MICALIS Unit (Philippe Langella laboratory, Jouy-en-Josas), at INSERM Hopital Saint Antoine (Harry Sokol laboratory, Paris), then at McMaster University (Elena Verdu laboratory, Hamilton, Canada). In the ENteRisk team, he will focus on the effects of xenobiotics on the microbiota-gut dialogue and the intestinal immune response, from the host development period (consequences for the newborn, then the adult). The objective is to evaluate the role of the intestinal microbiota in the "health" effects of food contaminants and chemical additives, particularly nanoparticles.
