I am an experimental economist interested in the psychological and cultural bases of human cooperation, particularly in an international context. I participated in the OECD-led Trustlab project, measuring trust in others and in governments internationally. I have directed experimental research in developing countries such as Colombia and Papua New Guinea. My research has been published in inter-disciplinary journals such as PNAS and Nature Communications. I have been a coordinating author in the International Panel on Social Progress, and taskforce chair on “Social cohesion and global inequality” in the Think20 network.
