A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds. Never before has anyone captured these two stars in so much detail. He publishes his data-cleaning method…

Two teams of astronomers, including one from Leiden University, have discovered oxygen in the most distant known galaxy, JADES-GS-z14-0. This groundbreaking discovery shows that galaxies could form much faster in the early universe than was previously thought.

Religion, Philosophy, and the Pre-modern World

In order to stimulate research and teaching within the field of medieval studies in the Netherlands the Research School for Medieval Studies offers the opportunity to submit requests for the (co-)funding of congresses, workshops and master classes for the period between 2022-2027.

How did free agents oppose the monopolies held by the VOC and WIC in court?

No one can tell you what it's like to work for us better than your future colleagues themselves.

Following the format of Privacy Law Scholars Conference (PLSC) in the United States, PLSC Europe is a conference for stimulating work in progress. Discussants, rather than authors, kick off and lead a conversation on a paper. There are no panels or presentations by the authors. Attendees read papers…

At the heart of this study is a thorough inquiry of categorisations of social identity used in the VOC’s record-keeping bureaucracy. How were service, occupational and caste groups classified and shaped by the VOC?

In this thesis we use state-of-the-art observations and simulations to provide the best constraints to date on the HVS ejection rate and constraints on the stellar content and dynamics at the GC, including the progenitor binary populations and their star formation history.

Explore the intersection of arts, literature, and media in this interdisciplinary research master’s programme. Whether you're interested in medieval manuscripts or modern digital culture, this programme offers the flexibility to tailor your studies to your interests.

This project is part of a broader research agenda aiming to better understand the relationships between the development of contemporary security concerns and the evolution of forms of security cooperation and crisis governance.

Exploring cultural production in Europe, Latin America and Africa, the institute’s research programme focuses on the continuous interconnectedness of the Arts and Society in both the textual culture of literature, learning and public debate and the visual culture of art, architecture, film, photography…

As part of your assignment you are required to contribute to teaching in the Bachelor and the Master programs in Bio-Pharmaceutical Sciences of Leiden University. You will supervise Bachelor and Master students during the research projects of the students in the laboratory.

In the South African context, certain iconic images have been a dominant source for public understandings of historical events. The emphasis given these images tends to overshadow the historical value of other more personal photographic sources – like studio or amateur photography. This project looks…

How can we monitor and protect biological and cultural diversity in Suriname best? What can we learn from local knowledge and customs associated with biodiversity? How can we understand current species, acoustical, behavioural, and ecological diversity from an evolutionary perspective? Can we predict…

Empathic or anxious mistakes? A neurocognitive investigation of the development of social performance monitoring in youth growing up in stressful versus non-stressful environments

Leiden University offers ambitious students a world-class environment in which to reach their full potential.

This book sheds new light on domestic forced migration by examining the experiences of American-born slave migrants from a comparative perspective.

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

The VVI seeks to advance knowledge of the formation and functioning of legal systems in their social contexts, the impact of these systems on society and vice versa, their effectiveness in governance, and their contribution to development.

This programme examines cultural space, national identity and the politics of tangible and intangible heritage in Islamic Central Asia.

The purpose of the initiative is to establish Central Asian Studies at Leiden University. Central Asia is a region with fluid borders stretching into present-day Afghanistan, Russia, China, Mongolia, Iran and the Caucasus; a premodern highway of global interaction and today increasingly important as…

We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

Since 2013, the National Natural History Museum of the Netherlands, Naturalis Biodiversity Center, is unearthing the largest bonebed of the horned dinosaur Triceratops discovered so far. In order to answer questions about sedimentology, taphonomy and palaeobiology, palaeontologists and geologists collaborated…

In the Aarts lab we combine or structure materials, mostly in thin film form, in such a way that the hybrid has different and novel properties or functionalities.

The application of compliance archaeology techniques such as mechanical large scale excavations where large quantities of data are gathered in relatively little time (and relatively inexpensively) and a firm post-excavation research phase yielded a whole new body of archaeological evidence.

The Graduate School of Archeology offers no longer the opportunity to obtain a full BKO certificate for PhD candidates. PhD candidates can opt for the partial BKO, especially designed for them, in which only the objective 3 and 4 are assessed: preparing and giving lectures and supervising students.
