The Dutch IT cooperative, SURF, which supports education and research institutions, has secured funding from the European EuroHPC programme to make this possible. Researchers from Leiden University will play a key role in the project,…

How can parents avoid passing on stress and mental health problems to their children? Professor of Stress-Related Psychopathology Bernet Elzinga develops simple interventions to help both parents and young people. For her research, she has been awarded the Spinoza Prize, the highest academic honour…

Hoping to learn something about the human brain, Leiden researchers are creating a setup to shoot single photons, particles of light, into someone’s eye. ‘The eye is a passageway to the brain.’

Physicist Sense Jan van der Molen researches materials that do not exist in nature. ‘It’s fascinating to see how the properties of a material change if we manage to make it super thin.’ He will give his inaugural lecture on 21 October.

An all-optical transistor, a molecule-sized sensor and a new kind of single-photon source for quantum communication. All dreamed applications of fundamental physics that are one step closer thanks to Robert Smit. On 12 June, he defended his PhD thesis with distinction.

Henk Hoekstra and Alessandra Silvestri work on the astronomy and theoretical physics in the Euclid mission. These Dutch researchers are part of the mission.

How does an embryonic stem cell decide if it becomes a heart cell or a kidney cell? That’s the question computational biologist Maria Mircea studied for her PhD research. She looked at the inside of individual cells to analyse how they change. This is what she discovered.

Friday afternoon, 1 October. Location: one of the most vibration-free places in the world. In this setting, Leiden top scientists launched Quantum Leiden. For decades, researchers at the Faculty of Science have been investigating quantum technology at the highest level and also have been brainstorming…

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

Francesca Albanese, UN Special Rapporteur for human rights in the occupied Palestinian territories, visited Leiden Law School on 8 December within the scope of International Human Rights Day.

The interdisciplinary programme Social Resilience & Security is inviting proposals for seed funding. The programme aims to combine knowledge and expertise from five different faculties to study transgressive behaviours, its dimensions, aetiology, and effects of interventions with a multidisciplinary…

On behalf of the interdisciplinary programme Social Resilience & Security, we would like to remind you of the call for proposals for seed funding (up to €4.000) to boost interdisciplinary research.

White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

On 14 July, the University Council discussed the draft version of the new ‘security framework’ with the Executive Board. This framework should make Leiden University’s security policy more transparent.

Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

A bloody civil war has raged for years in the Central African Republic. PhD candidate Crépin Mouguia points out a tragic pattern: young people have been recruited as fighters or soldiers for generations and thus fuel the conflicts.

Are you a PhD candidate, and is there something you’d prefer to discuss with someone other than your thesis director or supervisor? The confidential counsellor for PhD candidates is here to help. You can speak to him/her in confidence and receive advice. If you experience symptoms of physical or mental…

Many Leiden University employees engage in ancillary activities. The University stimulates such activities because we believe that the right place for a university is at the very heart of society. Ancillary activities bring together research, teaching and society. However, there are some limits on what…

Our confidential counsellors can provide confidential advice on a range of issues, including bullying, intimidation, sexual harassment, aggression and discrimination. You can also approach them with concerns about your manager or potential breaches of academic integrity.

Have you experienced or witnessed unacceptable or transgressive behaviour? This page gives information about what you can do yourself and which ‘helplines’ can assist you in this situation.

Health Day has won the LUF Relationship-Promoting Activities Prize (LUF RAP). This 5,000-euro prize is awarded to an initiative by Leiden University students that brings the academic community together.

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

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.

Studying surfaces of solid materials: it may not seem relevant to energy consumption, but it is. Marcel Rost studies how platinum electrodes wear out. Those electrodes are a crucial component in the fuel cells of hydrogen-powered cars. ‘We need to make the switch from fossil fuel energy to hydrogen.…

No less than six Leiden projects received a grant for quantum research from the national growth programme Quantum Delta NL and the NWO. After all, in order to boost quantum technology not only industry is needed, but also science. Research towards new sensors, faster algorithms and quantum materials,…

The University Council meeting on 2 June was largely dominated by the demonstration, occupation and policing in The Hague last month.

A delegation from Leiden University recently embarked on a knowledge mission to various NGOs, universities and government organisations in Indonesia. New partnerships were formed and important knowledge exchanged, and researchers from Leiden gave guest lectures.

Connecting scientific fields, enhancing research and teaching, and providing innovative solutions to complex social issues: that is the idea behind interdisciplinary research. What did the university achieve in 2024? A small sample.

Leiden University is under fire: it is allegedly doing too little to tackle antisemitism. Rector Hester Bijl responds to this accusation and to a video from 2014 on social media in which extreme remarks are made. ‘We can be short about such comments: they are unacceptable. The university is and always…

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…

The world is currently beset by many problems. The armed conflict and continuing violence in Israel and the Palestinian territories is resulting in numerous casualties. This is giving rise to many emotions and reactions worldwide, and also greatly affecting our own university community. We have seen…

A national walkout will be staged on Monday 13 May. Leiden Scholars for Palestine has called on students and staff from Leiden University to meet at 11.00 at the Lipsius building in Leiden and the Wijnhaven building in The Hague.
