What is the effect of pesticides, fertilizers or plastic on water quality? And how do wind and rain affect the data? These are just some of the things that Leiden environmental scientists study in the 32 ditches of the Living Lab.

(1) What are the institutional factors that influence AI adoption and implementation? and (2) How does AI reshape the exercise of administrative discretion within public organisations, and how do adoption and implementation choices moderate these effects?

Treatment and care for cancer patients is becoming increasingly advanced. For example, surgeons can now perform operations with much greater precision, and therapeutic vaccines are being developed to prompt the patient’s immune system to fight cancer. Work is also being done on better early diagnostics,…

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

Have you ever stood in front of an abstract artwork and thought: “a monkey could have done that!”. As it turns out, you are wrong.

This project has two main aims: I. Determine when novelty promotes fear extinction. II. Discover the neurobiological mechanisms underlying these effects.

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

You can find the Digital Lab on the ground floor of the Huizinga building (room: 0.09) on the Leiden University campus in Leiden. The Digital Lab is part of a collection of Humanities labs designed for staff and students who require a place to work, experiment, and find support for their digital res…

People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

This project is aimed at 1) elucidating the role of attention in itch and pain, including orientation, and attentional disengagement (i.e., directing attention away) from itch and pain; and 2) modifiability of these attentional processes.

Here you'll find selected publications and media attention from our group.

the production, use and exchange of bodily accoutrements through the lenses of the microscope

Would you like to take on an extra challenge during your LUC programme? Leiden University has some excellent programmes available for you to expand your horizons.

The oldest university in the Netherlands has produced many well-known scientists. Some of them are known to the wider public; others are perhaps less well known, but their achievements are no less impressive.

Meet Bart, Reza, Weiyan, James, Daphne and Yasmin.

The Microscopy Unit houses, maintains and coordinates most of the microscopy equipment of the IBL. The available equipment ranges from conventional light and fluorescence microscopes, to confocal laser scanning and electron microscopes. In addition, infrastructure is available for histology, including…

Neuroimaging research has greatly advanced our insights on how the brain is organized. Now is the time for the next step: Imagine what would be possible when we cannot only map brain-functioning, but use neuroimaging to voluntarily regulate brain-activity!

An academic program is only as successful as its graduates

With a MSc in Chemistry you are well prepared for a wide range of career opportunities. The chemical industry is one of the largest contributors to economic prosperity worldwide.

The Chemical Probe Facility is part of the Leiden Early Drug Discovery & Development (LED3) center. Activity-based protein profiling (ABPP) is one of the pillars of chemical biology. ABPP determines the activity of entire protein families in living cells and tissues under physiological conditions, such…

The goal of pre-clinical development is to bridge the transition from lead compounds to clinical candidates by comprehensively characterizing safety, efficacy, and pharmacological properties. Once a lead compound demonstrates promising activity in disease models, it enters pre-clinical development where…

How do contemporary authorship and scholarship work together to shape the way that early twentieth century literary and cultural movements are remembered today?

LED3 is the combined effort of four excellent institutes of Leiden University. Through joined hands, we are able to give rise to a more effective early drug discovery pipeline. Let us briefly introduce the institutes.
