Armelle Phalipon is a microbiologist leading a group within the Molecular Microbial Pathogenesis Unit, INSERM U786, at the Institut Pasteur, Paris, France. Working in the field of diarrheal diseases, her team is interested in deciphering the cross-talks between enteropathogenic bacteria and the host immune system. The main current studies aim at deciphering how Shigella, the bacterium responsible for bacillary dysentery, impacts on the development of the short-term, poorly effective protective immunity elicited in response to infection. Armelle Phalipon has a long-standing interest in combining fundamental and applied research. Indeed, in collaboration with Dr. Laurence Mulard (Institut Pasteur, Paris), she has designed a new type of Shigella vaccine candidate that will enter a phase 1 clinical trial in 2016 for proof of concept in humans. She is co-founder and co-director with Frédéric Tangy of the first International Vaccinology Course launched at the Pasteur Institute in 2008.
