Legal protection. What do those involved in youth care and child protection understand by this concept? And what needs to change to improve legal protection? This question was explored by researchers from Leiden University’s Department of Child Law. Their research fits with the government’s ambition…

A novel in vivo model system for studies on glucocorticoid resistance

On 15 November in Brussels, the Brussels Privacy Hub and the Future of Privacy Forum held the 6th edition of the 'Brussels Privacy Symposium'. The topic of this year was 'Vulnerable People, Marginalisation and Data Protection'.

Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it. After a few nerve-racking weeks of preparing the move and reinstalment, the researchers finally have a verdict: the instrument…

PhD defence

The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

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

The Algorithms and Software Technology (AST) research programme performs fundamental research in the areas of algorithm design and analysis.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

Lecture, LUCL Colloquium

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

The focus of the dissertation

Joanna Krenz defended her thesis on 15 May 2018.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Leiden University offers you several services related to career orientation and job application skills.

The specialisation High-Tech Innovation is for MSc students in Sciences who are interested in interdisciplinary technologies and research related to /important for high technology industries, e.g. the semi-conductor industry or nano-fabrication. In addition to their primary field of study, students…

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

The International Reynard Society studies the role of animals in the European literature of the Middle Ages and its afterlife. It focuses especially on beast epics, fables, and fabliaux. The 24th international colloquium of the Society – Of Foxes and Fish: Interdisciplinary Approaches to Medieval Animal…

In this project Principles and Best Practices for Insolvency Office Holders (IOHs) for cross-border insolvency cases are developed.

Legal education initiative of the Leiden University, the University of Groningen and Universitas Indonesia.

The Decolonising Collective Leiden is a platform for staff and students interested in exploring strategies to foster pluralistic, diverse, and decolonised knowledge production at Leiden University. While many discussions about decolonisation are ongoing in discrete spaces across the University, there…

At CWTS, we offer a range of educational and training activities designed to equip students, researchers, and professionals with the skills and knowledge to better understand the science system and its interactions with society.

The Children’s Rights Education Fund is an initiative that strengthens global leadership in children’s rights by offering financial support to students of the Advanced LL.M. in International Children’s Rights at Leiden Law School.

The Global Abolitionisms Network, established in 2015, is an international network of scholars working on antislavery activism and abolitionism. It is affiliated to the Leiden Slavery Studies Association.

Leiden University is developing a major new building at Spui, in the heart of The Hague. Set in a former department store, the building will house around 4,000 students and staff from Leiden University, Delft University of Technology, the LUMC and Universities of the Netherlands. It’s expected to open…

The Leiden Academic Centre for Drug Research (LACDR) has received a €750,000 grant from ZonMw for QPharmNL. This is a continuing education programme that trains professionals in computational techniques in pharmacology for innovative drug development.

In just over a decade, Uber has revolutionised how we move around our cities. The ride-hailing app was a game-changer: you just tapped your phone and a cab would find you. You even paid through the app. However, some of the Uber’s more controversial practices have triggered the interest of law enforcement,…

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

When you imagine a scientific conference, you might think of endless presentations and coffee breaks. But at the Lorentz Center in Leiden, things are a little different. Here, scientists don’t just listen—they collaborate, debate, and design the future of their field.

People with relatively high levels of lipids in their blood are less likely to develop allergic conditions such as eczema and asthma. These lipids cause genes that play a key role in allergic reactions to be less active. Researchers from the Leiden University Medical Center (LUMC) have published an…

The corona crisis has fuelled the discussion on social interests which has consequences for those looking out for these interests; it should be handled in a more socially responsible manner in which the government has an important role to play.

On 25 September, lights throughout Leiden will be turned off for the Seeing Stars event. What makes the urban night so special? We asked university lecturer Sara Brandellero, who researches cities, night and migration.
