Pulmonary infections


A large part of the IPBS research activity is dedicated to studying various aspects of tuberculosis and other lung infections. This includes lipid biochemistry and biogenesis of the mycobacterial cell envelope, virulence mechanisms and host-pathogen interactions, and immunity to mycobacteria and other lung pathogens. We are looking for a junior group leader in the field of pulmonary bacterial infection, with a strong focus on the biology of pathogens. Topics related to the followings will be favored: mechanisms underlying pathogen’s persistence, drug resistance or tolerance within the host. Deciphering the mechanisms of bacteria adaptation to their microenvironment will be a central question, and will benefit from state-of-the art approaches including, but not restricted to, single cell analysis, omics, microscopy and structural biology. In particular, our BSL3 animal facilities are fully equipped tissue and cellular imaging (including multiphoton intravital microscopy) and flow cytometry and cell sorting.
