The Citizen Science Lab brings together scientists, citizens and community stakeholders to arrive at new insights for both science and society through citizen science.

Leiden University's Citizen Science Lab supports and organizes initiatives where anyone can get started with scientific data and research. This is how we enrich research with insights from the community, make science accessible to all, and tackle important local issues together.

One of the goals of the Citizen Science lab is to be an incubator for citizen science projects. Over the years, the lab has been involved in creating and supporting various projects. Get inspired!

Do you have any questions about the Citizen Science Lab? Are you looking to participate in a local citizen science project? Do you want to establish a project for yourself and could use some support?

The Citizen Science Lab is located within the Center for Science and Technology Studies (CWTS) in the Faculty of Social Sciences.
