I am Research Director at the CNRS and Professor at the Ecole Normale Supérieure – PSL University in Paris.I am an evolutionary social scientist: I am particularly interested in understanding how our evolved cognition (e.g., morality, exploratory preferences, romantic love.) can inform the structure and dynamics of social and cultural phenomena such as social norms, religious beliefs, political institutions, fictions and the arts. To do so, I use all kinds of methods (experiments, surveys, data science, etc.) and materials (portraits, novels, etc.).
