Research

Motivation & Emotions

Why are people drawn to certain experiences and emotions over others? I study the computational architecture of human motivational preferences and why they vary across individuals. Drawing on personality psychology and behavioral ecology, I investigate how traits like Openness to Experience emerge from ecological conditions, and how emotions like fear and humor follow an adaptive logic.

Stories & Fiction

Why do people like different stories? I study how individual differences in personality and motivation shape preferences for stories, imaginary worlds, and other cultural products. Using computational methods and large-scale cultural datasets, I trace how these patterns scale to cultural change across societies and centuries, from ancient myths to modern entertainment.

Health & Public Policy

Why is there a gap between intentions and actions? The same motivational framework can improve health interventions. I develop and test personalized communication strategies that align public health messages and treatments with individuals' cognitive and motivational profiles, with the goal of improving engagement and behavior change.

Book

Histoire naturelle de la fiction

Why do humans invest so much emotion in stories that never happened? Drawing on evolutionary psychology and cognitive science, this book traces the deep origins of our fascination for fiction – from One Piece to Game of Thrones – and shows that these mechanisms emerged long before novels or cinema.
