Our leadership model consists of four competences that align with our core values. Each leadership competence expresses two opposing qualities. The goal is not to prioritise one of these qualities over the other, but to find the right balance between them. Effective leadership starts with awareness…

On 27 January 1900 thirteen female students gathered and established the Leesgezelschap van Vrouwelijke Studenten te Leiden (reading association for female students in Leiden).

Online platforms such as YouTube, Facebook, and X (formerly Twitter) have become part and parcel of everyday media use. Journalists incorporate posts from politicians into newspaper reports, scientists share their insights in short posts or videos, and the judiciary uses social media to explain their…

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

Quantum games aren’t just a fun way to explain quantum physics — they may also unlock new discoveries. According to physicist Evert van Nieuwenburg, these games create structure and clear rules. Simply playing them can even contribute to better quantum software.

The representation of death children in Dutch literature through time

In this work, I explore the creation of new methods that optimize simulations of the gravitational N-body problem. Specifically, I take advantage of the recent popularity of Machine Learning methods to find tools that can suit this problem.

Drawing on the analogical lessons of the Great War, this article uses applied history to analyze how the four parallels discerned can help us make sense of contemporary Sino-American rivalry

In this article, Thijs van Dooremalen and Philip Smith investigate how public discourse of heatwaves have shifted in British newspaper discourse, drawing on Raymond Williams’s theory of dominant, emergent, and residual cultural patterns to analyse changes in language and interpretation over recent d…

Brownian motion is the random motion of (colloidal) particles due to collisions with the atoms and molecules of the solvents, which are moving due to temperature.

Fokelien Kootstra defended her thesis on 23 April 2019

This book presents a new perspective on skateboarding, centred on the senses, skill acquisition, embodiment, and the concept of

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

In this lecture professor Harding considered the implications of Asia's 21st-century rise for its legal systems and our approaches to studying them in the new situation we confront in the early 21st century.

Simulating human language understanding on the computer is a great challenge. A way to approach it is to represent natural language meanings in logic, and to use logical provers to determine what does and does not follow from a text. What logic is best to use and how natural language meanings are best…

Books, prints or photographs, they exist to be read or viewed. But they are so much more.

If PhD candidates encounter problems, they should ask for help early on. If the problem is of an academic nature (in relation to research or teaching), their supervisors are the first port of call. If the issue falls outside the remit of the supervisors, there are several options.

Students in Leiden are entitled to good teaching and good supervision. For their part, there are some conditions they have to meet to ensure that they complete their studies within the time allotted.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

The chaotic years after the Civil War are often seen as a time of uniquely American idealism—a revolutionary attempt to rebuild the nation that paved the way for the civil rights movement of the twentieth century. But Adam Fairclough rejects this prevailing view, challenging prominent historians such…

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

Reasserting America in the 1970s brings together two areas of burgeoning scholarly interest.

This book presents a new framework for regulating human-like machines designed for emotional and sexual engagement, often powered by AI.

This book is about the workings of networks of the mobile in Africa, a continent usually associated with the ‘global shadows’ of the world.

Who are open-source intelligence activists and how reliable are their contributions to public understanding of Russia’s war in Ukraine?

This article discusses local expressions of crisis in Beed district, central Maharashtra. Both in public and academic discourse crisis has become the term of choice for the many structural deficiencies which make agriculture an increasingly precarious livelihood in India. While most voices subscribe…

From Complex Hunter-Gatherers to Early Urban Societies

This research cluster explores processes of cultural creation, reception and transformation within a wide range of societal contexts from the early Middle Ages until c. 1800.

How does the design of online participation platforms influence the inclusivity of online direct participation?

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

Leiden University would like to stay in contact with its alumni. That is why we try to keep contact info up to date, but we would also like to stay informed about where you are working after graduation and how your career is progressing.

In this article, Barrie Sander together with his colleagues explore whether fairness in digital governance inadvertently entrenches structural inequalities

For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

This book explores the intellectual and cultural flows between Asia and Europe which occurred during – and were formative of – the political and social changes of the first half of the twentieth century.

The Secret Life of Art Works. Exploring the Boundaries between Art and Life is the first collection of essays to present case studies from the visual arts, architecture, sculpture and numismatics, and to engage critically with theoretical perspectives from art history, psychology, aesthetics and ant…

This book was published in conjunction with an exhibition at the Pera Museum in Istanbul. It contains seven articles on the global panoramic visual history from the early modern to modern times and Istanbul's place within this history.
