Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

This research evaluates the Youth Act. It will provide an overview of how the transition takes place, whether the transformation process develops in the right direction and whether the legal safeguards are functioning properly.

The key questions posed in this dissertation centre on the interaction between spectator and artwork. What happens between a spectator and an artwork? How do we experience ‘meaning’ in an artwork? How may the process of interpretation be understood and articulated?

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

Archaeological and related essays on the Jordan Valley in honour of Gerrit van der Kooij on the occasion of his sixty-fifth birthday

When researching languages in historical context, our goal is to understand the nature of linguistic variation in the past, and explain the extent to which the socio-cultural context of bygone times contributed to shaping linguistic variation and change.

Understanding how nature captures and transfers solar energy is essential both for elucidating biological photosynthesis and for guiding the design of artificial light-harvesting systems.

Overview of the CML reports

The BLRN members have published extensively in recent years. In addition to the BLRN book series, dissertations of BLRN members published in the E.M. Meijers Institute Series, you will find below a selection of our publications. For a more complete overview of publications of each BLRN member, please…

The starting point for this research project is the notion that the human brain is susceptible to all kinds of fallacies and biases that affect our perceptions and influence our reasoning outside of our conscious awareness. Indeed, most people think they are merely observing facts and that they process…

The Vrijthof excavations (1969-1970)

Ariadne Schmidt, Isabelle Devos and Julie de Groot provide you with refreshing insights concerning the study on urban singles in the period between 1200 and 1900.

For many years, human rights have been considered a playing field in which states were the most important actors. In the present day society, this has changed as a consequence of globalization and the rise of multinational enterprises (MNEs). Protection of fundamental labor rights in global supply chains…

On the 26th of February, Joane de Lima Santiago successfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Joane on this achievement.

The central issue of this research concerns how students can best be supported in their study choice, study career and future orientation with a view to flexible entry and transitions and perspective in education and work.

Recent publications in the BLRN book series can be found below.

In 2024, many of our students and staff won great prizes and secured important research grants.

Is private law ready for the challenges of our time?

Using photosynthesis to generate energy, or using enzymes to effectively produce biofuel; Leiden chemists Huub de Groot en Hermen Overkleeft have both obtained an NWO TOP funding for their pioneering research. With the money they can take on new PhD students.

Hoe kan de City Deal Kennis Maken bijdragen aan het formuleren van maatschappelijk relevant onderzoek dat de stad in al haar diversiteit centraal stelt? In de stad Leiden zijn burgers momenteel maar in beperkte mate betrokken bij het bepalen van de agenda van de lokale City Deal Kennis Maken. Dit onderzoeksproject…

We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

Starting this academic year (2016-2017) Maartje van der Woude, Professor of Sociology of Law at the Van Vollenhoven Institute will organize the Leiden Socio-Legal Series (LSLS).

Climate change and energy transition were an important theme of the Dutch provincial elections: how should we invest in new sources of energy? Leiden University conducts multidisciplinary research into renewable energy solutions. Read more about this in the ‘Renewable Energy’ research dossier.

A Vici grant and a Science-GROOT: scientists from the Institute of Biology Leiden have been awarded prestigious grants from the Dutch Research Council (NWO). From investigating bacteria without cell walls to harnessing plants with the help of microorganisms.

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team headed by Huub de Groot imitated them and discovered how they function.

Professor of Clinical Pharmacology Adam Cohen from Leiden University received the prestigious Dr. Saal van Zwanenberg Honorary Prize on 12 November. The prize honours a scientist who has distinguished themselves in the field of research that has directly or indirectly led to the development of new medicines…
