The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

Van Vark defended her dissertation 'Separation and immersion: the changing role of the armed forces in Northwestern liberal democracies’ on 17 October 2025. The doctoral research was supervised by Maartje van der Woude and Erwin Muller.

Comparison across jurisdictions is one way of assessing the appropriateness of lethal force resulting from the actions of law enforcement agencies. This article sets out a vision for a global use of force monitor that can enable meaningful comparisons between law enforcement agencies. It examines some…

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

On 9 May 2018, Roy van Keulen defended his doctoral thesis 'Digital Force: Life, Liberty & Livelihood in the Information Age'. The doctoral research was supervised by Prof. dr. A. Ellian.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

This research aims to investigate how different social forces interact with hydropolitics in the Eastern Nile Basin and what are the constraints of engagement.

Welcome to the Social Anxiety and Specific Phobia (SASP) Research Group!

A story of Two Mosuls, The Resurrection of the Iraqi Armed Forces and the military defeat of ISIS. In this article, published in the Journal of Strategic Studies, the authors Maarten Broekhof, Martijn Kitzen and Frans Osinga discuss the military adaptation by the Iraqi armed forces and their role in…

Lecture

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

The development process of any software has become extremely important not just in the IT industry, but in almost every business or domain of research.

This research examines the social, political, and cultural forces that structure people’s responses towards accented speech, and further uses the accent as a focal point to theorize the interrelation between language and body.

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

On 9 January 2019, Willem van der Muur defended his thesis 'Land rights and the forces of adat in democratizing Indonesia'. The doctoral research was supervised by Prof. dr. A.W. Bedner and Prof. dr. J.M. Otto.

During times of domestic turmoil, the use of force abroad becomes an appealing strategy to US presidents in hopes of diverting attention away from internal conditions and toward a foreign policy success.

Tuberculosis bacteria survive by hiding in our immune cells. In her PhD research, biologist Salomé Muñoz Sánchez explores how boosting the body’s own defenses might outsmart this deadly pathogen. Her work reveals two key proteins that help immune cells destroy the bacteria.

From basic science to real-world interventions

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

Can a newly developed, app-based, personalized maintenance program enhance the effectiveness of the exposure-based one-session-treatment for children with a specific phobia?

This dissertation aims at enhancing our knowledge of whether a CI provides sufficient access to auditory speech input to acquire verbal morphology by comparing outcomes of CI children to those of their normal hearing peers and to those of children with specific language impaired (SLI).

How have the armed forces of the United Kingdom, the Netherlands and Belgium adapted to the OMLT task in Afghanistan, and what institutional changes have materialised as a consequence of this adaptation?

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

Leiden researchers discovered that North Korean labourers are being forced to work on a large scale in Poland. Professor of Korea Studies Remco Breuker will present a report on the abuses in Poland at the ‘Slaves To The System’ conference on 6 July.

Researchers at Leiden University and the National Autonomous University of Mexico (UNAM) have launched an initiative to learn more about the experiences of migrants travelling through the Darién Gap, with a focus on forced migration.

In Film and Video Intermediality, Janna Houwen innovatively rewrites the concept of medium specificity in order to answer the questions “what is meant by video?” and “what is meant by film?”

Proteins organize themselves around our body cells through a self-induced force. They indent the cell membrane, which makes them roll towards each other. This discovery provides new insights into processes like nutritional uptake and brain signaling, as well as into such diseases as Alzheimer’s. Publication…

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Political scientist Corinna Jentzsch (Leiden University) about the organisation of rebel and government auxiliaries in the civil war in Mozambique (1976–1992).

William Lippert investigates the effect of delegation to an agreement executor on success of conventional arms control agreements in Europe.

In this thesis, we describe the potential of cell mechanical phenotyping for immune cell characterization, diagnosis, drug testing, as well as treatment of disease.

Leiden researchers found a way to measure the tiny forces exerted by pericytes, one of the most elusive, hard to research cell types, which occur in tiny blood vessels. Building on this fundamental science, researchers may eventually find treatments for medical conditions like ischaemia.

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

The civil lawsuit against the Congregation of 'Onze Lieve Vrouw van Liefde van de Goede Herder' starts this week. A total of 19 women, aged from 62 to 91, together with the women’s rights foundation Clara Wichmann wants recognition through the courts that there was a situation of forced labour at youth…

In this project, the hypothesis that language contact crucially impacts the development of spatial grammar and phonology is investigated.

Microneedles represent promising tools for delivery of drugs to the skin. However, before these microneedles can be used in clinical practice, it is essential to understand the process of skin penetration by these microneedles.
