They are not always in the spotlight but are essential to our scientific research: Leiden research support professionals. And their network is growing and professionalising all the time. Over a hundred such professionals shared knowledge and gained inspiration at the Leiden Research Support Network…

How can our university really become inclusive? This is what students and staff discussed at our annual Diversity & Inclusion symposium. ‘It’s moving from a have-to to a want-to’

Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

On 15 January, the winner of the famed LION Image Award will be announced. Submissions ranged from the famous 3d printed microboat to an eerily abstract graph depicting a Majorana fermion.

The annual LION Image award goes to the 30 micrometer long 3D printed microboat image that went viral earlier in October 2020, submitted by Rachel Doherty of the Daniela Kraft lab.

From human rights in Sudan to a new cult of heroes in China. During the board members' visit, the Institute of Private Law and the Institute for Area Studies clarified their social relevance in no uncertain terms. What's happening here in education and research?

Most young alumni who graduated during the COVID-19 pandemic did not get a graduation ceremony, nor did they have the chance to sign their name in the Sweat Room. Thanks to the Alumni Office, they now have the chance to do so after all.

For the second year in a row, we had to hold the spring symposium as an online event. But nevertheless, there were impressive presentations and interesting poster pitches.

Scientists have detected a neutrino with the highest energy ever measured. Leiden physicists Maarten de Jong and Dorothea Samtleben were involved in this project, which was widely covered in newspapers and online media last week.

On Friday June 2, the Liveable Planet event 'Interdisciplinary Collaborations - Food, Sustainability & Health' will take place. Here, researchers can learn everything about how to set up successful interdisciplinary collaborations. Why should you attend this event? We’ll give you three reasons.

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

What is freedom worth in times of hunger? ‘Beleg’ is a modern interpretation of Lucretia van Merken’s 1774 play. With five performances in Leiden’s Schouwburg theatre, the play is a prominent part of the Relief of Leiden celebrations, and Leiden alumni are playing a big role. Take a look behind the…

Alex Colling himself calls his bachelor's thesis ‘the highlight of his time in Leiden’. And according to his supervisors, that resulted in an outstanding thesis, with great attention to detail. The Mathematics and Physics student worked on a mathematical description of monopoles: hypothetical particles…

It will be on the agenda of many a team meeting these coming weeks: how can we act on the results of the Personnel Monitor? We asked two managers how they have gone about this, what the results of their meetings have been and whether they have any tips for their colleagues.

The highly successful deep-sea telescope KM3NeT can now expand both its size and scope. Using a new type of microphone for underwater use, the telescope will attempt to detect the sound produced by neutrinos as they travel through the sea. The data collected will also be of great interest to other research…

The experiential expertise of people with a disability needs to be integrated in diversity & inclusion policy. This message was the common thread at the annual Diversity & Inclusion symposium. Students and staff members engaged in conversation about how the university can become more accessible.

The new Neurodiversity Platform supports staff who need better working conditions because they have ADHD or autism, for instance. Stefan de Jong, who is organising the Platform’s first online meeting on 15 November, tells us about the initiative. Register now if you’re interested.

An international team of researchers led by astronomers from Leiden University (the Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth's ionosphere. They used the new method to study…

The Citizen Science Netherlands (CS-NL) network was officially launched this month with the aid of an Open Science NL grant. The new vision for this network was presented on 28 May.

Medewerkers van de Universiteit Leiden trappen maandag 10 maart de estafettestaking af van de Nederlandse universiteiten tegen de kabinetsbezuinigingen.

Recently, our respected and talented former colleague Bente Hilde Bakker passed away after a long and brave fight with illness. She received her mathematical training at the Vrije Universiteit in Amsterdam and also obtained her PhD there under the supervision of Jan Bouwe van den Berg and Robert van…

The teams that will lead the themes guiding Leiden University’s strategic positioning in the coming years have been formed.
