Associate Professor of Social and Environmental Psychology, University of Amsterdam, Netherlands
Our lab studies how individuals and organizations respond to collective-action problems such as climate change. We focus on actions with high environmental impact, regardless of motive. Our work ranges from consumption (clothing repair, recycled products) to collective and institutional action (policy support, activism, university air travel). We also study trust in science and climate communication, and aim to measure actual behavior, because intentions often diverge from action.

Policy Impact and Consulting
I consult for companies, universities, and governments with clients such as the European Commission, United Nations, University of California, Defra, UK Cabinet Office, UK National Rail, Fairphone, Open Evidence, and the Cambridge Institute for Sustainability Leadership.
See this report of media attention, policy document citation, and societal impact. On the right, I spoke in Cambridge about communicating for influence (14 min).
