We are transparent about our research involving laboratory animals, which includes providing access to our annual statistics. On this page, you will find an overview of various aspects, such as the number of animals and the species we use, the types of research for which we employ animals, and the level…

Leiden archaeologists have been digging into the municipality of Oss’s past for 50 years now and students have gained their first experience of fieldwork there. What is the result of half a century of research and teaching? Archaeologist Richard Jansen and his students take us to the largest excavation…

The project seeks to come to an understanding of the archaeology of the desert and the ways in which its inhabitants engaged with their constraint, marginal environments through time. It compares and interprets site distribution and community organisation over a long time scale and across several different…

On Friday 24 March, Prof. Amanda Perry-Kessaris (Kent Law School) will deliver the monthly Leiden Socio-Legal Lecture.

It doesn't happen every day that the research project of a first-year bachelor’s student results in a scientific publication. And not only that, but as first author and on the cover of a leading physics journal. ‘We have given our lab education a thorough overhaul and it is paying off.’

The Vrijthof excavations (1969-1970)

Jasper de Bruin, Guus Besuijen, Hans Siemons & Jeroen van Zoolingen (2012). De romeinse nederzetting bij het tegenwoordige Goedereede heeft waarschijnlijk een belangrijke functie gehad in de overslag en distributie van diverse goederen, waaronder keramiek en voedingsgewassen. De opgraving van deze nederzetting…

The aim of this project is to gain a better understanding of daily life, diet, mobility and health in late medieval Zeeland, as well as to test the potential of multi-isotopic analyses on a Dutch assemblage.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

Experimental research

Adhesives are an incredibly important part of every day life. They help hold together everything from shoes and mobile phones to satellites in space. But we didn’t invent adhesives: Neanderthals did, to make handles for stone tools over 191,000 years ago. Leiden researchers now found that Neanderthals…

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

The programme offers you the ability to combine experimental research with theoretical courses. The programme helps you grow into an independent and skilled physicist.

On May 31st, Bobby Ruijgrok succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Bobby on this great result.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

Welcome to the Hensen Lab! We are a young dynamic experimental research group starting at the Leiden Institute of Physics. Our lab addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity.

The overall theme of this thesis is to complement the electrochemical data acquired in fuel cell research with in situ X-ray photoelectron spectroscopy (XPS) and soft X-ray absorption spectroscopy (XAS).

The ultimate goal of the PhD program is the preparation and successful defense of a PhD dissertation.

How do atoms and molecules end up forming planets? That's what astrochemist Julia Santos studied during her PhD. She discovered the dominant process behind the formation of methanol in space – a finding that surprised the entire field.

On Friday 10 November 2017 the annual Janneke Fruin-Helb Scholarship was awarded to alumna Matilda Sebire. She graduated in the master's specialisation in Material Culture Studies.

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

Sip2021 is sponsored by the Dutch Research Council (NWO) and the Graduate School Experimental Plant Sciences (EPS).

In this study Lilie Roosman describes the effects of prominence and boundary marking on the temporal and melodic structures of two regional languages of Indonesia, viz. Toba Batak, a stress language, and her native language Betawi Malay, a non-stress language.

Our mission is to advance the understanding of mental health of individuals with a history of stress and/or trauma through rigorous interdisciplinary research, integrating insights from clinical psychology, neurobiology, and social sciences. We are committed to translating our findings into innovative…

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

Research at the Leiden University Centre for Linguistics (LUCL) focuses on linguistic variation and diversity. In order to create more awareness and scientific understanding of this topic, research activities are clustered around six (overlapping) umbrella programmes. Many of our researchers are active…

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

Making systems biology modelling a central pillar of research in biology

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

The programme’s courses deal with current approaches in material culture theory, advanced methods and techniques from the exact sciences employed in artefact studies, and experimental archaeology.

World-class research is integral part of the master’s education. You obtain a Physics degree from an institute with an international reputation. Research in this programme is fundamental and curiosity-driven.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…
