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?

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.

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…

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.

The research at the Living lab attracts a great deal of press attention. Please find below a small selection of the many news reports that have been published. Also take a look at the Zembla programme about the Living Lab.

A History of Modern Political Thought in East Central Europe is a synthetic work, authored by an international team of researchers, covering twenty national cultures and 250 years. It goes beyond the conventional nation-centered narratives and presents a novel vision especially sensitive to the cross-cultural…

On Wednesday 23 October 2024 Judith Jurjens successfully defended a doctoral thesis and graduated.

This study investigates how two social and political developments, in the UK and Germany, impacted on the experiences of minorities and the attitudes of majorities vis-à-vis tolerance in those two countries. The results provide a thought-provoking picture of the views of minority and majority groups…

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.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Representing Japanese Colonial 'Heritage' in Taiwan

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…

This open access book brings together an eclectic cast of scholars in related disciplines to examine ageing in the Soviet Union, covering the practice of geriatrics, the science of gerontology, and the experience of growing old. Chapters in the book focus on concepts and themes that analyse Soviet ageing…

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Our current research focusses on the exploration of the Universe using the neutrino. This neutral, almost massless and only weakly interacting particle can open a window to the distant Universe and also dense regions from which photons cannot escape.

What is the current relevance of the ethics of counterterrorism and what is the added value of ethics support within the practice of counterterrorism?

Social aspects of the learning environment, also called classroom climate, are important for students’ cognitive and affective learning outcomes. In this thesis the classroom climate is operationalised by means of two components: the teacher-class relationship and classroom discipline.
