John Caffier

Hi, I am John – a psychologist and software developer, and an External PhD candidate at Tilburg University, co-supervised here at the University of Mannheim. I graduated with an M.Sc. and B.Sc. in Psychology from the University of Konstanz and with a B.A. in Media Studies & Political Science from the University of Tübingen. After my studies, I was a Visiting Researcher for one year at the Max Planck Institute for Human Development in Berlin. My research focuses on how large language models and social media shape trust, persuasion, and prosocial behavior. When I am not analyzing data or building apps, you’ll likely find me meeting friends, tasting Greek food, chasing the sun, or playing board games. Click here to view my CV.
