How can staff help create a healthy and inclusive learning environment? How do today’s students differ from previous generations? And what does this mean for how we guide and support them? These questions were the focus of the ‘Today’s Students’ symposium on 25 March.

How can we continue to work on an open university culture where everyone’s contribution is recognised and rewarded? Over 120 university staff spoke about breaking academic barriers at the first Academia in Motion Festival in PLNT.

It’s not healthy but we often do it anyway: sit hunched at our computer for hours on end. But exercising and relaxing at work doesn’t have to be complicated. These staff members have come up with fun and easy ways to help their colleagues stay fit and healthy. ‘You don’t need sportswear and won’t end…

Paul Wouters came to the Faculty of Science for a few months to help with organising day-to-day issues after the previous dean left. This has involved rather more than he expected. ‘I can now really understand why every faculty has its own dean.’

You need not be completely miserable in your current job to start a discussion about your professional development. And if internal career coaching still feels like too big a step, you can take a look at the university’s Career Platform instead.

At the age of six, Barbara Gravendeel already knew what she wanted to be: a biologist. The seed was planted in the garden of her childhood home: an old orchard surrounded by a large hedge. Since 1 May, she has been the scientific director (prefect) of the Hortus botanicus in Leiden, and all the pieces…

The new government needs to look further ahead, says environmental scientist Rutger Hoekstra. ‘We keep pushing forward big dossiers like demographic ageing, climate and migration. Even though we know they play a big role in our future.’ Hoekstra therefore hopes that the new coalition agreement will…

So many interesting programmes, but which one suits me best? It was the Bachelor’s Open Day in Leiden and The Hague on Saturday 12 October. Among the many things to do in The Hague, prospective students could find out more about three new bachelor’s programmes: Science for Sustainable Societies, Cybersecurity…

An international team of astronomers has revealed the first 'chemical profile' of an exoplanet's atmosphere. The team, including Leiden astronomer Yamila Miguel and provenda Amy Louca, made the profile using so-called Early Release Science data from the James Webb Space Telescope. The results have been…

What can you do about sustainability in your immediate living environment? On Thursday afternoon, April 14, the Museum Volkenkunde in Leiden was filled with policymakers, researchers, entrepreneurs, citizens, students, and even the mayor of Leiden. Leiden University and the Association of Dutch Municipalities…

Two deans: one leaving and one just arriving. Paul Wouters was deputising at the Faculty from March up to December. As of January he returns to his 'ordinary' role as dean of the Faculty of Social Sciences. Jasper Knoester is taking over from him, as he will be leaving Groningen for Leiden. How did…

This Thursday, January 18th 2024, our esteemed colleague Jan Zaanen passed away. Jan was one of our star scientists, larger than life, with an unabashed, boisterous drive for the best of physics at the Institute Lorentz, at the Leiden Institute of Physics and in the full international scientific community.…

At the Faculty of Science, forty per cent of the employees are of a non-Dutch nationality. Amongst PhDs that is even sixty per cent. How are they doing in a time of working at home in a different culture, when travelling is not possible? Clinical pharmacologist Lu Chen is the third in this series to…

Jaïr van Rhenen studied Medicine in Leiden and is now a GP in the largely religious Veenendaal. Before this, he worked as a tropical medicine doctor in Lesotho. ‘If you have the prospect of an afterlife, you often respond differently to illness.’

Frans de Haas started his work at the MI with a clear mandate. Listening and talking are what he will mainly be doing ‘My role is to make sure that everyone feels comfortable in the new situation.’

Countries that import plastic waste recycle an average of at least 63 percent of it. This is surprising, as we previously believed that the vast majority was incinerated or ended up as litter. This was discovered by PhD candidate Kai Li and his colleagues from the Institute of Environmental Sciences in…

On January 16, 2022, our respected and beloved colleague Prof. dr. Bas Edixhoven passed away after a short period of serious illness.

Sinéad Mulcahy recently started the Europaeum Scholars Programme, a two-year policy and leadership course for a group of thirty talented and committed PhD candidates from universities across Europe. She is already enthusiastic – both about the programme and her fellow scholars. ‘I would like to bring…

How do you set up a successful collaboration between science and practice? That was the main theme of the final meeting of a triptych of symposia on how Leiden University can improve inter- and transdisciplinary collaboration.

On 28 October 2021 there is an online information session about the two-year Scholars Programme of Europaeum. This network brings young researchers and leaders together to discuss developments in Europe and to promote pan-European thinking. Does that sound interesting to you? Would you like to know…

Holocaust scholars Barbara Engelking and Jan Grabowski will jointly hold the Cleveringa lecture on November 26. They were accused of defamation in Poland for a book they co-edited. How has this affected them? ‘This is an attempt to wear us down.’

Space telescope Euclid is capable of unravelling the secrets of the universe. That is what the images published by ESA today show, according to astronomers working with the telescope's data. The images exceed all expectations. Scientists within the Euclid consortium, including astronomers Henk Hoekstra…

Siemens recently took over the Leiden software company Culgi, founded by professor and inventor J.G.E.M. (Hans) Fraaije. We spoke to him about the algorithm that made him successful, the role of a university in our society and his ambitions at Siemens. ‘I was looking for Siemens, and they were looking…

Eleven researchers from Leiden University have been awarded an Open Competition Domain Science ENW XS grant by the Dutch Research Council for their research projects. They are researching how to make software faster and greener, improve cancer detection and reduce anxiety by manipulating the biological…
