My research interests lie in exploring the evolution, provision, and maintenance of public and common goods in both natural and social settings. I apply theoretical models based on evolutionary game theory and energy flows, as well as conduct behavioral studies on cooperation, trust, and fairness in humans. My work particularly focuses on investigating the impact of social structure on group formation, polarization, and other key aspects of social life that influence collective action and the provision of public and common goods.
