What are the social and neural mechanisms that contribute to fluctuations in self-esteem in healthy adolescents and adolescents with depression?

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

Delineating psychophysiological endophenotypes of social anxiety disorder

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

Synthetic or artificial cells are vesicles, often lipid vesicles, with wide ranging applications from drug delivery to nanoreactors in biocatalysis. We are developing polymer-lipid hybrid vesicles for applications in compartmentalised biocatalysis, in which the polymer has been shown to greatly enhance…

On 14 December, Jouke Tegelaar defended the thesis 'Single supervision, single judicial protection? Towards effective judicial protection in Single Supervisory Mechanism composite procedures'. The doctoral research was supervised by Matthias Haentjens and Willemien den Ouden.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

In this article, Lydie Cabane, Assistant Professor at the Institute of Security and Global Affairs, and Martin Lodge address the question of how to manage banking crises, a question that has gained prominence since the banking crisis of 2007-2009. This article sets out the rationale for regulating for…

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

This thesis focuses on the development of sample-preparation methods for small amounts of samples and applying the developed methods to muscle tissues to investigate the mechanisms involved in sarcopenia.

Valedictory lecture

This course explores international arbitration as one of the most common methods of international dispute settlement. You will gain an in-depth understanding of international arbitration through the analysis of its role as a mechanism of dispute settlement, its institutions, the fields of law it is…

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

Are you curious about how science and technology contribute to a sustainable and innovative future? At Leiden University, you’ll explore the world of data, natural laws and living systems. From mathematics to artificial intelligence, from climate challenges to high-tech innovation: you’ll learn to analyse…

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

The High-Tech Innovation specialisation consists of a 60 EC track alongside the students' core MSc programme: Astronomy, Chemistry, Computer Science, Mathematics and Physics.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).
