How can citizen science increase public trust in science and foster equity in the research system? The
Centre for Science and Technology Studies (CWTS) of Leiden University has an opening for a postdoc researcher (0,8 fte) for 24 months to carry out a research project funded by the Dutch Research Council (NWO) under its OS-NL Research on
Open Science funding instrument. While earlier research about this topic has addressed the people actively participating in citizen science (CS) projects, we will investigate the perceptions and perspectives of citizens, researchers and policy makers who
do not directly involved in such projects. The project will study four CS projects in the domain of environmental science, using a survey, individual interviews, and focus group interviews.
