The findings of this research will be presented with Dr. Joris van den Tol (Radboud University)…

Interest organisations are increasingly taking legal action and that’s a good thing for democracy, says PhD candidate Rowie Stolk. ‘It means that the most vulnerable social groups – including children and refugees, who tend to have a weaker political position – are protected.’

On Friday July 10th LUC The Hague marked another milestone and challenge surmounted by hosting its first fully-fledged online graduation ceremony for the class of 2020.

Karwan Fatah-Black of Leiden University, an expert in the area of Dutch colonial history, wrote the text for a slavery remembrance memorial that was unveiled on 1 July in Hoofddorp.

What if a major world event alters the trajectory of your research project? Tsolin Nalbantian was studying citizenship along the Turkish-Syrian border when the Syrian Civil War erupted and led to a global refugee crisis. While her research participants were forced to flee the region, she was forced…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

Ms. Kollmann, a home care worker in the Netherlands, is demanding pension and unemployment benefits from the Dutch Employee Insurance Agency (UWV). An exception in the law means that home carers working for private individuals are not automatically entitled to benefits under social security schemes.

For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…

A stretchy sheet over a bowl representing space, a marble on it's surface creating a dimple, deforming space. Simple classroom experiments like these are featured in new educational videos by AstroEDU. In the videos Leiden astronomers Maria Cristina Fortuna and Henk Hoekstra explain what we know of…

The Data Archiving and Networked Services (DANS) accepted the request for subsidy to digitise the archive of the archaeological fieldwork at Tell Deir Alla in the eastern Jordan Valley. The subsidy comes from its KDP-program (Small Data Project) and is meant to promote digitisation of important datasets.…

The Netherlands returned 478 artefacts to Indonesia and Sri Lanka this week, on the advice of a Dutch committee. Rightly so, says Leiden professor Pieter ter Keurs from the Museums, Collections and Society interdisciplinary research programme. ‘But do make it clear why you are returning something.’

Cases have been brought against YouTube and Reddit for spreading conspiracy theories. They are accused of being behind the radicalisation of a man who took the lives of ten black people in Buffalo, New York, almost two years ago. But can they be held liable? Michael Klos discusses this in 'Trouw'.

The small quantum world and our world of perception obey different laws of nature. Leiden physicists search for the border between both worlds. In an article published soon in Physical Review Letters they set an upper limit.

At the end of the 7th century something curious occurs in Northwestern Europe. Suddenly, people start burying the dead next to their dwellings instead of in communal cemeteries. Professor Frans Theuws recently published a book on this phenomenon. ‘We wanted to know if the study of these farmyard burials…

What hidden nature is there in our cities and how can we use such organisms? This is what the HiddenBiodiversity project will be exploring over the next four years. The project’s kick-off meeting was held at the Hortus botanicus on Monday 26 September.

A ‘world class institute’ with a ‘vibrant atmosphere’, doing research on a continent that is ‘becoming increasingly important’. That is how Annetje Ottow, president of Leiden University’s Executive Board, described the African Studies Centre Leiden (ASCL) on its 75th anniversary celebration on 8 September…

Four researchers from Leiden University have been awarded prestigious Vici grants the Dutch Research Council (NWO) has announced. The honoured applications are from researchers at the Faculty of Social and Behavioural Sciences, Leiden Observatory, the LUMC and the Faculty of Archaeology.

It was not light, but its absence that caught Stephanie Noach's attention a few years ago. With her research on darkness in art, she aims to show how darkness can question and sometimes even undermine colonial imagery.

Cars are equipped with catalysts to disarm toxic exhaust gases. Platinum plays an important role there. Leiden physicists and chemists have now for the first time seen the mechanism behind a platinum catalyst. With a fundamental understanding of the process, scientists can use this rare material more…

The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument.

Rietje Knaap’s (83) PhD was a real feat of endurance, but she persisted. ‘You’re married so you don’t need a pension, do you?’ What are the experiences of Knaap and women who followed in her footsteps? In the run-up to International Women’s Day on 8 March, three generations of female doctors look back…

Non-urban settlement organization and Roman expansion in the Roman Republic (4th-1st centuries BC)

Engagement between Asia and Europe is increasing. If these continents want to build a lasting relationship, they need to understand each other better in the economic, socio-cultural, historical and legal arena. Researchers from Leiden have already contributed to the body of knowledge on past and present…

At the Faculty of Archaeology, we investigate the development of human societies worldwide, from the earliest beginnings to modern times. We also study the heritage of mankind, which evokes this deep history, and which connects with, and informs, contemporary society.

The Heritage Sector at a Crossroads: The way of Intersectionality. This project investigates how heritage institutions can achieve inclusion and accessibility within their organization, collection, and exhibition spaces that meets the breadth of demands placed by today’s “critical visitors.” Fifteen…

Leiden Law School has a strong tradition of research in the field of fact-finding and evidence in criminal cases.

It is more myth than reality that people with migration backgrounds commit more crime. Leiden has successfully tackled anti-social behaviour by Moroccan youths, says former mayor Henri Lenferink. Good education forms the basis of a healthy and safe society, says ‘crimmigration’ researcher' Maartje van…

On this page you will find an overview of awards and prizes granted to our staff and students in 2024, as well as special appointments at Leiden University and other institutions.

If a young person from a migrant background climbs the social ladder despite internship discrimination, the exclusion often gets worse. It is only when we acknowledge these problems that we can resolve them, say Nadia Bouras and Tikho Ong, who are both experiential and academic experts. ‘Racism and…

Space for open dialogue on historical slavery was created at the Keti Koti Table at Museum De Lakenhal, organised by Leiden University and the Municipality of Leiden.

The Astronomy & Society group of Leiden Observatory takes a new turn in science: they have decided to share their rejected research proposals with the scientific community. ‘We put a lot of effort into them, and now hopefully others can benefit from our work. Maybe it even results in new collaborations,’…

Streptomycetes are similar to moulds, but these bacteria live in the soil. They are very popular in biotechnology because they produce a great many antibiotics and enzymes. Gilles van Wezel will be using his Vici subsidy to study ways of increasing their production.

After every attack, terrorism researchers are often asked the same question: who did it? Jeanine de Roy van Zuijdewijn, a researcher at Leiden University, doesn’t always have a ready-made answer.

Simon Portegies Zwart, professor of Computational Astrophysics, uses computers to simulate the evolution of stars. We speak with him about his field and about the challenges of working with huge amounts of complex data.
