We are pleased to present this symposium featuring commentary from participants in the “Critical Studies of Citizen Science in Biomedical Research” conference held on the March 2, 2017, at King’s College London. Organized by different projects concerned with citizen science in Kiel (A. Buyx) & London (B. Prainsack), Exeter (S. Leonelli), and Geneva (B. Strasser), the event took a critical look at the role of citizen science in biomedical research in the 21st Century.
