On Architecture Day, residents of The Hague had the chance to take a look inside Spui Campus.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life. Jasper first wrote his column from Kuala Lumpur, and it was ready to share. Then a crisis arose this week that demanded…

Leiden University has had a diversity policy since 2014. The aim is to create a diverse and inclusive learning and working environment for all students and staff. Diversity Officer Aya Ezawa updates us on the process and the results. It’s now 2022, what has already changed?

From academic freedom to security and medical breakthroughs: during Leiden University’s 451st Dies Natalis, the speakers reflected on the role of universities in a world of social and geopolitical tensions.

With great sadness we share the news that Prof. Harold Linnartz passed away suddenly and unexpectedly on Sunday 31 December 2023. We are all in shock, and our thoughts are with his wife and children, other family, and friends. Harold was at the heart of our institute, as a researcher, as a supervisor,…

No more lectures and exams for the Radio Astronomy course taught by Michiel Brentjens. The corona crisis is a moment of reflection that has changed his whole way of teaching. Instead of being in front of the class, he lets his students build a radio telescope with paint cans.

Education

The opening of the new academic year highlighted students' and lecturers' personal motivators. Incoming students were encouraged to be bold, forge their own paths and grow by trial and error.

How has progress been made on diversity and inclusion at Leiden University over the past decade? Attendees reflected on this at the D&I Symposium 2024: Untold Stories. And in the workshops, students and staff discussed the next steps toward a more inclusive community.

To mark Leiden University’s 450th anniversary, this exhibition pairs historic photographs with contemporary research. Seven ‘Then & Now’ diptychs show how the Institute of Physics blends a rich past with cutting‑edge science.

He was a popular face in the Leiden student world and even developed his own merchandise, but all good things come to an end. After seven years, community support officer Dennis Perdok (49) is leaving this role. Last week he bid farewell to the police and to his job in Leiden’s city centre.

Leiden University and the Leiden Bio Science Park can make a significant contribution to the earning capacity of the Netherlands. This is the finding of the National Investment Agenda presented today.

Thursday 15 January starts with a long journey and ends with an equally long working day full of current issues. Jasper visits the Mathematical Institute with the scientific directors of our faculty and attends a meeting on collaboration with the Ministry of defence.

From practicing ultrasound techniques in augmented reality to chatting with virtual ancient Greeks about what an archaeological site looked like back in the day: video & innovation specialist Nathan Saucier gives an insight into the many possibilities of the interactive media and simulations studio…

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

Are magnetic fields older than the first light? And how did they influence the development of our universe right after the Big Bang? Cosmologists from Leiden, Groningen, and Utrecht are now collaborating to investigate this.

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.

What is the best way to restore dune ecosystems? The project TERRA-Dunes researches the role of soil microbes in the development of natural dune areas. Recently, the project went into a new phase: planting 412 oak seedlings grown in different type of soils.

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip?

Each research institute has its own dynamic. The Executive Board is visiting our institutes to find out what they are up to. On 24 June, it was the turn of the Institute for History. ‘History helps us make sense the present, whether through family stories, local issues or world politics.’

A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

Het college van bestuur heeft Wim Voermans benoemd tot Universiteitshoogleraar. Hij gaat zich richten op duurzaam institutioneel vertrouwen.

When you think of a library, you probably picture books – or students quietly studying. But for subject librarian Rutger de Jong, most of the work happens online. ‘We never throw anything away. Everything produced here in the name of science should remain findable.’

To better prepare students for their laboratory education, a team of education experts and students have created a collection of interactive videos. After launching their website labprep.video, the material is now available to everyone in higher education. Project leader Marjo de Graauw: ‘We also created…
