Sacha Bourgeois-Gironde is a former student of the Ecole Normale Supérieure (Paris) and currently a faculty member at Institut Jean-Nicod (Paris) and Ecole Normale Supérieure (Lyon). He is an analytic philosopher whose research is mainly pursued at the disciplinary interface between cognitive sciences and behavioral economics. His theoretical and empirical work bears on the analysis of human rationality and its limits, in particular of the nature of cognitive and affective biases which affect our reaching optimal behavioural patterns. The main question raised through Sacha Bourgeois-Gironde's recent research program is the study of the biosocial mechanisms that guided our adaptation, and partial maladaption, to modern economic environments and artifacts, such as money. Tools he uses include experimental economics methodologies, brain-imaging and clinical studies, field studies and large-scale questionnaires. Sacha Bourgeois-Gironde is the author of several books and numerous scientific articles, among which La Neuroéconomie (Paris, Plon, 2008) et Comment l'argent vient à l'esprit (Paris, Vrin, 2009).
