Cutting-edge technological innovation for businesses and consumers, enabled by top-tier research on space and the quantum world.

When and how does social anxiety develop? How can it go astray in some adolescents? How can we help troubled young people to attend school regularly and return to a normal developmental pathway?

Our courses are aimed at higher educated professionals, starters, experienced professionals and managers. You can choose from day-long Masterclasses, multi-day courses and an intensive one-year program. Our offer exists off on the themes below.

What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodiversity, and Ourselves, Menno Schilthuizen reports from the front lines of evolutionary biology, on a quest to make sense of the origins, workings and evolution of our and other species’ reproductive selves.

How do the pathways of Dutch converts to Islam involved in jihadist movements differ from those of Dutch converts who are not, in terms of their life prior to Islam, their conversion experience and the form of involvement with the Islamic community after conversion?

What did we do over the past year? Well, we played quantum games, helped develop an instrument for the Extremely Large Telescope and started a new bachelor's programme. Oh, yeah, and we officially opened our brand new Gorlaeus Building! Warm up the fingers and get ready to click and scroll through…

From Incident to Precedent

Rising geopolitical tensions are causing states and national elites to innovate their use of the past for present-day political ends. This is certainly true for the People’s Republic of China, which celebrated its 75th anniversary in 2024 amid mounting superpower rivalry, ideological tensions with the…

The Secular Outlook describes what moral and political secularism means. It paints the image of a world view in which state and religion are kept well separated.

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Lecture

Seagrass is a marine flowering plant with special adaptations to coastal and marine environments, playing a crucial role in providing a wide range of ecosystem services.

Sub-Saharan Africa has seen a significant rise in terrorist acts and radicalized youth since the appearance of Boko Haram in 2009 and the fall of Libya in 2012. This book investigates the deeper layers of radicalization in Sub-Saharan Africa, which is situated in a larger global tendency.

This PhD project investigates the distribution and interpretation of quantity expressions in relation to the mass/count distinction cross-linguistically.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

In dit onderzoek worden orde isomorfismen en orde antimorfisme bestudeerd in het algemene kader van partieel geordende vector ruimten.

This book provides a long-term historical analysis, exploring the roots of the low levels of corruption existing in Chile, going back to the 16th century and examining Chile’s institutional evolution until today.

In this publication, Prof. Tahir Abbas, Inés Bolaños Somoano, Joana Cook, Isabelle Frens, Graig R. Klein and Richard McNeil-Willson look into the manifesto that was linked to the Buffalo attack in order to better understand the broader context and specific factors that motivated the perpetrator.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

This ethnographic exploration of anticipation published in the Journal of the Royal Anthropology Institute draws on fieldwork among people with dementia and their families in the Netherlands.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

We use laboratory animals to address research questions, but only when there is no alternative and the question cannot be answered in any other way. Read here why we conduct animals experiments.

PhD defence

’25 years of fatal violence’, a collaboration of dr. Marieke Liem and prof.dr.Lenneke Alink about murder and manslaughter in the Netherlands, has received a research grant by the Leiden University Fund.

With a special symposium at Museum Boerhaave, ESO celebrated its 60th anniversary on Monday, 26 September. More than 100 scientists, politicians and people from industry were present to look back on collaborations, milestones and discoveries. Leiden astrochemist Ewine van Dishoeck was one of the pre…

Tonal bilinguals of two closely related Chinese dialects are amazing people. They handle two tonal systems in their mind; their two vocabularies are from closely related dialects, and they write translation equivalents with common Chinese characters. Their unique language situation makes their mind…

People who are arrested on suspicion of preparing an attack are at risk of becoming radicalised either during or after their detention. Whether or not to arrest someone requires careful consideration. At the end of the prison sentence, it is important to provide effective supervision of the reintegration…

Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

How do people acquire language? How can you train your brain? What is the effect of stress on an unborn child? LIBC research topics range from language processing to cognitive robotics, and from psychiatric disorders to the impact of social factors on human behaviour. Meet several main research topics…

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

As part of the selection process of Leiden University College, we ask students to attend an LUC sample class. The classes on offer are one hour in length and are offered online. We expect you to switch on your camera during this class, so that it mimics a real class as much as possible. The teacher…

Social anxiety runs in families, but the neurobiology underlying this genetic vulnerability is until now largely unknown. The unique Leiden Family Lab study on Social Anxiety Disorder (LFLSAD) aims to broaden our knowledge with respect to this genetic susceptibility.

This is an Erasmus+ International Credit Mobility project of Leiden University with the Hebrew University of Jerusalem.

The ability to count is a property not often attributed to materials, despite the abundance of memory in materials. Regardless of how a material stores information, it is often difficult to retrieve exactly ‘what’ a material remembers.

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.…

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.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.
