A liveable planet. More biodiversity. And resources which are being managed wisely. At the CML, we want to make an impact with our research and education. On this website you can read what we do to achieve that.

In which way and to which extent is integration articulated in concept maps and which factors affect the resulting concept maps? By which factors is the perceived usefulness of such concept maps affected?

The RISIS project aims at creating a distributed research infrastructure to support and advance science and innovation studies. This will give the field a strong scientific push forward, and at the same time, provide a radically improved evidence base for research and innovation policies, for research…

Although the world has made tremendous progress in health, education, sanitation and hygiene, global public health challenges still exist. Disparities in health exist between and within nations as evidenced by inequalities in disease burden, mortality, nutrition and environmental well-being. How does…

At the start of the 20th century there were fewer than 2 billion people. Now at over 7 billion, Earth’s population is on target to reach 8 billion by 2027.

How do processes of coalition-formation influence patterns of decision-making in the European Union?

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

How we think about and act on the usefulness of scientific research has epistemological and political implications: what knowledge consists of, how it comes about and to what ends. In this dissertation, I situate the usefulness of scientific research in concrete places for knowledge exchange. The exchange…

The new cabinet threatens to cut nearly a billion euros from higher education. This not only endangers academic work, it is a disaster for the Netherlands itself. The proposed penalty on study extensions and other financial measures will heavily impact students and will reduce education accessibility.…

The Leiden Bio Science Park (BSP) will become a real campus in the coming years, with more houses, and attractive places where scientists, students and entrepreneurs can meet to discuss their plans.

Bacteria caught red-handed, deeply frozen just as they were about to cause Lyme’s disease. Ariane Briegel is wildly enthusiastic about the wonders she observes thanks to three elements: a freezing technique, a camera-equipped microscope, and AI. ‘It’s fascinating. Every single cell is different.’

The Minor in Teaching was introduced in 2009 as a new initiative to introduce and prepare bachelor students for teaching. Student numbers are low, however, especially of mathematics and science students.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

From the beginning of Galileo’s career, well before the publication of the Sidereus Nuncius, his contemporaries took pains to shape his reputation and fame. They were fully aware that their efforts would shape the course of his career; they also knew that they would profit from helping him.

From 1550 onwards, a great interest in the natural world developed across Europe. This interest was not only stimulated by a growing knowledge of local flora and fauna, but also by the import of numerous exotic animal and plant species. Think, for instance, of researches and collectors like Gessner…

Bringing science, technology and innovation to places that normally do not have access to these areas of knowledge. This is the goal of the first Open Science Hub in Portugal, founded in 2017 in collaboration with Leiden University. The hub is managed by assistant professor of astronomy and society…

How does the government know whether science policy has the desired effect? According to Professor Barend van der Meulen, a variety of evidence about the effectiveness of science policy and proper gathering of this evidence are more important than a strict scientific method. Inaugural lecture 27 Ma…
