On Monday 27 October, Jasper goes on safari in the Van Steenis building. And will he manage to stay dry more often than he gets soaked cycling between meetings? You’ll find out – along with the rest of Jasper’s day – in this column.

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.

To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

With our campaign ‘Check it: work privacy and security smart’, in the coming month we are focusing on protecting our information and data, including personal data.…

Interdisciplinarity is more than a buzzword in academia. It’s essential for tackling today’s biggest challenges. But what does it look like in practice? How can PhDs learn the skills needed to work across disciplines, and how can supervisors master the art of guiding them?

Marlon Titre (1982) studied at Royal Conservatoire The Hague, did his PhD and studied at Leiden University, earned several other qualifications and is now, among others, Director of Filmhuis The Hague. Who is this multi-talent?

The university is home to many pearls of research institutes that do not make the news every day. The Executive Board visited one such pearl, the Institute of Philosophy, on Tuesday 1 July. It resulted in an inspired conversation.

How can we cooperate better as a Faculty? Both with each other and with the outside world. Around 70 students and staff discussed this during the latest strategy session in Corpus. Keynote Harry van Dorenmalen, former president of IBM Europe: 'You know best what this Faculty stands for and what it n…

Marlien van Mever delved into the analysis of tiny samples, cerebrospinal fluid from transgenic mouse models for example. She validated methods that can now be used to study brain diseases such as migraine and epilepsy. Van Mever will receive her PhD on 14 June.

‘A challenging rollercoaster, but also a very bonding and insightful experience,’ that’s how the team of iGEM Leiden 2022 wraps up their participation in the iGEM contest. The contest for synthetic biology climaxed during the Grand Jamboree in Paris. The team ended up in the top 10 of over 360 teams…

What looked like an ordinary coot’s nest turned out to be a five-star location with a remarkable backstory. Beneath a jetty on the Rokin in Amsterdam, biologist Auke-Florian Hiemstra discovered a true time capsule — complete with face masks from the COVID era and a Mars wrapper dating back to the 1994…

In the short term, no reorganisation is foreseen within the Faculty of Humanities, nor are any compulsory redundancies expected. Nonetheless, structural changes remain necessary. This is evident from the faculty’s draft budget for 2026 and the accompanying financial multi-year outlook.

The Schoof cabinet has presented its budget. As expected, higher education is facing severe cuts. In the coming period, the Executive Board will regularly look at the consequences of what it deems an irresponsible policy.

Various meetings will be held over the next few weeks to discuss organisational development at Leiden University. On the agenda are a vision of organisation and management, an exploration of the central services organisation and a teaching logistics programme.

This committee, created by Rector Magnificus Hester Bijl and consisting of former and present Leiden University researchers, has been tasked with assessing Leiden University’s institutional ties with organisations…

On Wednesday 5 November, Jasper sets off on the annual study trip for the Board of Deans together with the Executive Board. Because of budget cuts, they’re staying a bit closer to home this year. But that doesn’t make the trip any less enjoyable — as you’ll read in this column.

It is a familiar phenomenon: you ask the assistant on your phone to call your mother, but it calls a friend instead. Tom Kouwenhoven, PhD student in the SAILS programme, investigates how humans and Artificial Intelligence (AI) can better communicate with each other, so that these kinds of situations…

They make up no less than 73% of the workforce at the Leiden Institute of Chemistry (LIC), yet PhD candidates and postdocs at the institute don’t always find their way to each other. LIC73 aims to change that. The platform organises social and professional activities and amplifies the voices of these…

How can groundbreaking research help Europe tackle the huge challenges it faces? At the launch of the Leiden Europe Hub, academics and policymakers discussed this in the heart of European democracy: the European Parliament.

On January 1st Jasper Knoester started as our new dean. How is he finding it? What kinds of things is he doing and what does his day look like? In each newsletter, Jasper gives a peek into his life as dean.

Western civil servants openly struggle with their government’s policies on the war in Gaza. During a meeting at Campus The Hague, three former civil servants told their stories.

Her father is a miller, so it’s hardly surprising that Esther van der Ent is also fascinated by windmills. Alongside her work at the Centre for Environmental Sciences (CML) and the Leiden-Delft-Erasmus alliance, Esther is now training to become a miller herself. ‘This craft mustn’t be lost,’ she say…

How do you really measure how a country is doing? Researcher Annegeke Jansen is looking for alternatives to gross domestic product (GDP) to assess the state of society. As an economist, she focuses on well-being, inclusivity, and a healthier environment. ‘The economy should be a tool to achieve those…

‘What if we switch off all the lights one evening? That idea crossed my mind from time to time. And when I mentioned it to a taxi driver one day, he said: “Oh, you mean: lights out, stars on!” That’s not completely true, of course, because the stars are always on, but his phrase summed up the idea n…

How safely do you handle your data? Privacy officer Eric van Hoof assists researchers and staff with this. 'The biggest mistake people make is thinking they have nothing to hide.' He has some useful tips.

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

How can you figure out which points lie on a certain curve? And how many possible curves do you count by a given number of points? These are the kinds of questions Pim Spelier of the Mathematical Institute studied during his PhD research. Spelier received his doctorate with distinction on June 12.

Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

Her plan was to obtain a PhD, but, during her master’s, alumnus Sangbreeta Moitra discovered that her true interest lay in applying neuroscience in everyday life.

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…

The Netherlands is embroiled in a complex nitrogen crisis. Berent Baris wants to use his NitroGenius game to demonstrate the complexity of this crisis.
