This forms the base for the presentation-training course for young researchers organized by the Centre for Professional Learning.…

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

Sex without mutual consent is a criminal offence. The proposed new Dutch sexual offences law aims to better protect victims of sexually transgressive behaviour. But the key issue is this: the rules of evidence have not changed, so will victims actually benefit from the new legislation?

The Dutch polder model has provided stability and administrative calm for many years, but is it still resilient enough to withstand the dynamics of today, or is it ‘too rigid’?

Although it can be a challenge at times, parents should keep communicating with their teens. Also about how they parent. Research by developmental psychologist Loes Janssen shows that parenting can be perceived quite differently by family members and mood plays an important role. Parents often parent…

The annual commemoration of the nation’s war dead on Dam Square and at Waalsdorpervlakte, the Dutch apologies for historical slavery and the Cleveringa Lecture itself: our relationship with history is often ritualistic, Cleveringa Professor Frank van Vree will say in his inaugural lecture on 27 Nove…

New ministers, new state secretaries and new members of parliament.

Dutch children’s picture books are full of animals, but mainly mammals are portrayed. Especially pets and exotic animals are popular. A large part of the Dutch fauna is less visible, but biologist Michiel Hooykaas of Leiden University sees plenty of opportunities for a more biodiverse book world.

The number of international organisations has increased over the last decades. As has the number of cities interested in housing these organisations. International organisations bring wealth to cities and help improve their reputation. They often act as a magnet for other international corporations.…

The gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

Last year he became Teacher of the Year because of his innovative and online teaching, now Alexander van Oudenhoven has to change course again and teach physically. What have the first weeks been like for him? ‘Let's apply what we learned in the lockdown period.’

‘A tax crusader’... that’s how Ferd Grapperhaus, former Professor of Tax Law at Leiden University and father of the former Minister of Justice and Security, described himself. In his biography of Grapperhaus, Assistant Professor Rens Pieterse explains that he saw tax as a contribution to society.

Assistant professor Joost Willemse firmly believes that as a teacher, you’re never done learning. ‘Students ask questions about things you’ve never thought of yourself. Ultimately, that makes you better at your job.’ That’s why he always encourages his students to ask questions. And it’s appreciated:…

Behind the relatively stable income inequality in the Netherlands, big changes have been happening. Income inequality has increased over the past 40 years, but less sharply because women in lower income groups have begun working more. In contrast, men’s income has increased very little over the past…

Anyone who wanted to get an impression of the Dutch East Indies between 1800 and 1945 quickly turned to travel literature.

Data about COVID-19 were everywhere during the pandemic, but how will all this data continue to be managed and kept open so that it is usable in the future? We spoke with Kathleen Gregory, researcher at the Centre for Science and Technology Studies (CWTS), who will study this question in a new project…

Sharing scientific data, transferring money, or sending other sensitive information online: with cryptography, applications make sure your data does not fall into the wrong hands. Mathematician Thomas Attema (CWI/TNO/Leiden University) helps with this. For his PhD research, he developed a new technique…

Food security touches upon human rights, international law and sustainable development. These frameworks are not separate worlds but deeply interconnected; something that becomes painfully clear in times of climate crisis, armed conflict and inequality.

Always taking the same route to work, going for that one dish in restaurants and going on the same holiday each summer: this may ring a bell for those who don’t like uncertainty. Researchers are now discovering that this aversion affects how we understand the world.

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

It’s already in the name. Everything you tell a confidential counsellor is confidential. In fact, a confidential counsellor is even liable if they breach their duty of secrecy and confidentiality. Considering all the recent reports in Dutch media of unacceptable behaviour, more attention than ever is…

The elections finally seemed to be about substance again. Housing, migration, healthcare and security were widely discussed. Yet once more, political style took centre stage - because both Rob Jetten and Henri Bontenbal won through a deliberate use of style.

Security seems to most people a basic necessity of life, a prerequisite for a good life. But if you think about it a little longer and deeper, as political philosopher Josette Daemen has done, you realise that security sometimes comes at the expense of other important goods, such as freedom and equality.…

On Friday 29 August 2025, 370 students received their Bachelor's degree in International Studies. The diplomas were awarded in the historic setting of the Pieterskerk in Leiden.

When an international cartel is exposed, the parties involved often face punishment by more than one authority for the same behaviour. There is very little international coordination in the actions of these authorities. Pieter Huizing claims that this can, and must, change. PhD defence on 10 March 2…
