Leiden researchers Arjen Doelman, Tom Huizinga and Manfred Wuhrer have been awarded ERC Synergy Grants worth millions of euros for their research on preventing tipping points being reached in ecosystems and helping eradicate rheumatism.

Pandemics, terrorist attacks, environmental disasters... These are real threats, which we cannot ignore. In fact: we need to prepare better for the large-scale crises of the future. Preferably in a way that suits our lifestyle and respects our social values. Over the next ten years, an interdisciplinary…

Two directors. Both professors of mathematics, but one of them is a biologist. One comes, and the other goes. Roeland Merks will succeed Arjen Doelman as director of the Lorentz Center in September. What has been accomplished and what are the plans? And above all, what makes the Lorentz Center so un…

We have to do all we can to stop climate change. But: the Earth is more resilient than we thought. That is the surprising conclusion of an international team of ecologists and mathematicians, which included Leiden mathematician Arjen Doelman. The team discovered that ecosystems can still avoid tipping…

At the first Climate Café of 2025, we celebrated the one-year anniversary of The Hague Climate Agreement and reflected together on the successes and opportunities for the future.

Roeland Merks is the new director of the Lorentz Center as of 1 September. He has been appointed for a period of five years. In addition, Merks will remain associated with the Institute of Biology Leiden (IBL) and the Mathematical Institute (MI) as a professor. Merks succeeds Arjen Doelman, who has…

The Lorentz Center is 25 years old. A good reason for them to contribute to a series of TEDx lectures for Leiden City of Science. Arjen Doelman, director of the Lorentz Center, was the first to enter the virtual stage.

The winner of this year’s Iris Medal for Excellent Science Communication is Professor of Science Communication Ionica Smeets.

What do we really know about educational quality and its measurement? This was the subject of the first Higher Education Knowledge Café.

Ionica Smeets is planning to give the prize money that she won with the Iris Medal, a prize for excellent science communication, to student projects.

Multidrug-resistant pathogens and worldwide pandemics are increasing, making infectious diseases more prevalent. To develop new treatments, deeper knowledge of the interaction between bacteria and human cells is required. Ariane Briegel recently became a Medical Delta professor and studies such path…

How can social scientists contribute to a healthier society? That question was central to the Healthy Society Event on 9 June 2022, which successfully marked the start of a more conscious and intensive collaboration between the five Institutes of the Faculty of Social and Behavioural Sciences on education…

'Let's make this a twice-yearly tradition!'– a feeling shared by many after the vibrant Research Day. Engagement started early, with participants connecting informally over good coffee before the formal start of the event on 19 November.

Arjen Doelman (Leiden University), Max Rietkerk (Utrecht University), Ehud Meron (Ben-Gurion University of the Negev) and Isla Myers-Smith (University of Edinburgh) received an ERC Synergy grant of 10 million euros with their RESILIENCE project. The researchers will investigate whether and how tipping…

Mathematics can help predict thrombosis. Mathematician Mark Alber has developed models that even aid in suggesting treatments. In the Kloosterman lecture on 27 June, he will explain how this works.

How to strengthen mutual trust between agencies in the criminal justice system and youth with a migration background or weaker socio-economic position. The Netherlands Science Agenda has awarded 1.5 million euros to a consortium to find out.

Leiden University and the Municipality of The Hague signed a collaboration agreement on sustainability on 1 November. Their main goals are to build a network, share knowledge and explore the possibilities of a Climate Centre for the people of The Hague.

Dutch politics has long been a paragon of stability. Think, for example, of our party system until, say, the last decade. At the same time, we also see occasional changes and significant shifts. Society has changed and this is reflected in, among other things, how we vote and how policy is made. About…

Even though the COVID-crisis continuously evolves and is marked by new realities and uncertainties, we can carefully begin to take stock looking back on the first phases of Dutch crisis management. What can we learn reflecting on the crisis strategies of this extraordinary and transboundary crisis that…

A few weeks ago, Dutch pension giant ABP decided to divest from fossil fuels. But is this actually going to help the climate? Natascha van der Zwan, Arjen van der Heide and Philipp Golka (Institute of Public Administration, Leiden University) address this question in our new article for S&D.

Lecture, Tuesday Talks: Science Insights

This academic year saw the start of the Change Lab(oratory) project. Teaching staff from various departments worked on innovations in their master's courses: 'It’s a privilege to improve your teaching and get so many useful tips in the process.'

The Lorentz Center is a melting pot that is visited by researchers from around the world. ‘Miracles happen’ during the five-day interactive workshops at the Center. And there is an extra reason to celebrate the center’s 25th anniversary. On 28 April, the Dutch Research Council (NWO) and Leiden University…
