Short bio
I direct Annecy Behavioral Science Lab and am PI on LONELY-EU, where I co-lead the work on measurement instruments. Twenty years on social connection; author of Heartwarming; co-founder of the Psychological Science Accelerator. Based on Lac d'Annecy. Ask me about measurement — particularly whether between-person instruments tell us anything about an individual. Interest declared: I co-founded Entrelacs, which builds personalised measurement of social connection.
