Students, staff, visitors, and Leiden residents can then study, work, and live in a pleasant environment. The Humanities Campus is in open connection with the city of Leiden…

This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…

Didactics, Career development

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.

The objective of this project is to understand the content and structure of science teachers’ knowledge and beliefs, and how these change in the context of pre-service teacher education and educational innovation.

What is and should be the role of universities in supporting business? How can business benefit more of relationships with science? And what is the role of policy makers in supporting a productive relationship between science and business? Professor Simcha Jong Kon Chin examines the interactions between…

In September 2023, we will be transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.
