All players on the world stage operate strategically in order to safeguard their interests. Political scientists at Leiden University cast light on this volatile interplay of forces. Their research helps voters, NGOs, governments and international organizations make smart choices in this complex and…

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…

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.

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.

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.

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.

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.

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.

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.

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.

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…

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.

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.

’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…

This one-year, English-taught Master's programme offers insights on general developments as well as the specific challenges in the field of the governance of crisis and security, with in-depth knowledge of sub-fields of crisis and security management.

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…

The Terrorism and Political Violence research group at Leiden University examines the causes of radicalisation, the tactics of extremist groups, and the effectiveness of counter-terrorism policies. We also explore the role of the media and the influence of postcolonial legacies in the Global South,…

Polarisation in our society is on the rise. What makes people increasingly radical? How do we protect ourselves from extremist, terrorist or criminal threats, be they physical or in the cyber world? And what role do intelligence services play in this?

Electrocatalysis is a promising approach to address various environmental and energy challenges including greenhouse gas mitigation, renewable fuel generation, and electrifying hard-to-abate chemical sectors. Electrochemical CO2 reduction reaction (CO2RR), for instance, could contribute to lowering…

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.

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…

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…

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

Leiden University is organising two international conferences on security from 7 to 10 November in The Hague. Power relations, negotiating with extremists, cyber espionage, and the experience of a real crisis situation are some of the issues on the agenda. The conferences will be opened by Mayor Jozias…

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.

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.
