Christophe Guignabert is professor of Molecular Biology & Physiology and leads the INSERM research Team “Endothelial dysfunction & Therapeutic innovation” at the Université Paris-Saclay, France. His research focuses on the molecular and cellular mechanisms behind the process of vascular remodeling in Pulmonary Hypertension in order to identify and validate new therapeutic targets. In particular, his research is focused on how dysfunction in the BMP/TGF-β superfamily modulates the phenotypic heterogeneity of the pulmonary endothelium and on how pulmonary endothelial cells interact with their environment.
