Admission requirements

This course is an (extracurricular) Master Honours Challenge aimed at talented 3rd (and on) Bachelor's students and Master’s students. Admission will be based on academic background, GPA and motivation.


In this Impact Challenge, you will develop and perform a citizen science project: doing research in collaboration with the general public.

For many problems facing society today, scientists are trying to find solutions through their research. This societally relevant research can contribute to greater sustainability, healthier lives or increased well-being. However, for this kind or research to have impact it is important to collaborate with societal stakeholders and the general public. This can be done through citizen science. Citizen science means the active collaboration with the public in scientific research through data collection or analysis, but also through defining research questions or drawing conclusions. In this course, you can find out how citizen science works and you will perform your own citizen science project, in collaboration with a researcher from Leiden University.

You will work in interdisciplinary teams with a coach (a scientist at Leiden University) on their proposed citizen science project, in fields ranging from biodiversity to safety and public health. You will also collaborate with other stakeholders such as the municipality and “Learning with the city” (Leren met de Stad).

  • Project Search for New Antibiotics will focus on the sampling of soil in search of antibiotics-producing and resistant bacteria. Participants will sample and research their samples in collaboration with microbiologists and chemists. Possibly in collaboration with school groups.

  • Project Urban Nature Regarding Climate Change will focus on building a monitoring platform of citizen scientists who are collecting environmental data in Leiden and combining their data to learn about the role of urban nature regarding climate change, pollution and well-being.

  • We are working to add another project related to public health.

You will learn more about the links between science and society: how can society inform research and how can research support societal developments? You will develop and conduct a research study related to a societally relevant topic, involving stakeholders throughout the entire research process. At the end of the course you will have developed a working citizen science project and will give recommendations about the future of the project. You will also present your findings towards relevant target audiences (municipality, residents, community members, depending on the topic).

Course objectives

  • know how citizen science can create a link between society and science;

  • be able to collaborate with different stakeholders including (local) government, policy makers, citizens, societal organisations;

  • be able to perform interdisciplinary research;

  • apply creativity, originality, social concern to the project.
