Christophe Pierreux, Professor UCLouvain and Maître de Recherche at F.R.S.-FNRS, is a biologist from UNamur that obtained his PhD degree in Biomedical Sciences at the de Duve Institute/UCLouvain. He spent two years as a postdoctoral fellow at the Imperial Cancer Research Fund (now, the Crick Institute) in London, UK, and then moved back to the de Duve Institute in Brussels. In 2008, he was appointed Chercheur Qualifié at F.R.S.-FNRS and developed his own research group at the de Duve Institute with a focus on intercellular communications during pancreas and thyroid organogenesis. His group demonstrated the critical role of endothelial cells on epithelial morphogenesis via the production of soluble and sedimentable, i.e. extracellular vesicles, factors in the environment. More recently, he also focused on EVs in thyroid cancer development.
