Dr. Dridi received his Accreditation to Supervise Research (HDR) in Structural Biology, Biochemistry and Cell Signaling from the University of Paris XI. He got his PhD and Master degrees in Molecular and Cellular Biology from the National Polytechnic Institute of Lorraine (INPL) and National Institute for Agronomic Researches (INRA), France.

Research Interest

His research interests include: Peripheral and central molecular mechanisms involved in the regulation of energy homeostasis and fat metabolism in avian species for the improvement of growth efficiency.

Scientific Activities

Dr. Dridi joined several international teams such as UNC-Chapel Hill, University of Kentucky, University of Leuven (Belgium), ENITA Bordeaux (France), ENV Nantes (France) and West Virginia University as a post-doctoral fellow, Contractual Professor or Main Investigator.
