Nabil Djouder obtained his PhD in Molecular Pharmacology from the University of Strasbourg (France) and the University of Freiburg (Germany). In 2001 he moved to Basel (Switzerland) as a postdoctoral research fellow and joined the laboratory of W. Krek at the Novartis Friedrich Miescher Institute. In 2003 he became a member of the Competence Centre for Systems Physiology and Metabolic Diseases (CCSPMD) and in September 2009 he joined the CNIO as a Principal Investigator establishing his group in the field of Growth factors, Metabolism and Cancer.
