  • Bio: Mehdi Khamassi is a research director employed by the Centre National de la Recherche Scientifique (CNRS), and working at the Institute of Intelligent Systems and Robotics (ISIR), on the campus of Sorbonne Université, Paris, France. He has a double background in Computer Science (Engineering diploma in 2003 from Ecole Nationale Supérieure d'Informatique pour l'Industrie et l'Entreprise, Evry with specialization in Artificial Intelligence and Statistical Modeling) and Cognitive Sciences (Cogmaster in 2003 from Université Pierre et Marie Curie (UPMC), Paris). Then he pursued a PhD in Cognitive Neuroscience at UPMC and Collège de France between 2003 and 2007. He serves as co-director of studies for the CogMaster program at Ecole Normale Supérieure (PSL) / EHESS / University of Paris. He also serves as Editor for the several scientific journals, like Intellectica, Frontiers in Neurorobotics, Frontiers in Decision Neuroscience, ReScience X, and Neurons, Behavior, Data analysis and Theory. His main topics of research include decision-making and reinforcement learning in robots and humans, and the role of social and non-social rewards in learning. His main methods are computational modeling, design of new experimental protocols to test model predictions, analysis of experimental data, design of AI algorithms for robots, and behavioral experimentation with humans, non-human animals and robots.
