Dura Vermeer seeks to create a green and playful neighbourhood with welcoming public spaces as its…

Martina Huber, Jacqueline Labra Munoz research Alzheimer's disease. They study ferritine, iron storage in the brain. An inbalance of iron could play a role in this form of dementia.

Chronic pain, nausea or vomiting due to chemotherapy. If you suffer from such ailments, medicinal cannabis can be a godsend. Though a downside is that it can make patients high. Therefore, Leiden researchers from the Oncode Institute are investigating alternatives that do not make you high. In Nature…

Leiden researchers Max van Duijn (Leiden Institute of Advanced Computer Science) and Vasilika Kosta (Leiden Law School, Europa Institute) will join The Young Academy (Royal Netherlands Academy of Arts and Sciences) KNAW)).

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

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.

In a speech on Keti Koti the Dutch king, Willem-Alexander, apologised on behalf of the royal family for the Netherlands’ historical role in slavery. What is the significance of this?

PhD candidate Jiangnan Ding explores how you can design a thick slab of rubber in a way that it might act as a mechanical computer bit. This so-called mechanical metamaterial is pushed in a specific way to change its shape. ‘With a very simple material, we might be able to do simple calculations in…

Physicist Kaveh Lahabi’s research on quantum materials led to the launch of a new company: QuantaMap. With his colleagues, he developed a sensor that will improve the production of quantum computer chips. ‘It turns out that what I need for my fundamental physics research is also very useful for the…

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

On 21 June, our beloved colleague Joan van der Waals passed away after a long and rewarding life.

Without academic freedom, we might not have antibiotics, nor a deep understanding of human behaviour. Literary criticism, climate models, and ecological restoration would be severely limited; just like ethical reflection on artificial intelligence, justice, trauma, parenting, faith and hope. All these…

The US-Israeli strikes on Iran have been welcomed by critics of the regime but have also prompted intense concern. They’ve triggered a dangerous domino effect across the region and beyond. Leiden experts share their insights on the potential consequences.

Towards the end of February, three Leiden University buildings will be assessed for their accessibility to people with a disability. The assessment will be carried out by Ongehinderd, a social enterprise committed to making the Netherlands more accessible. Its founder and director, Gerard de Nooij,…

Leiden University is part of a Dutch consortium that will receive 4.7 million euros from NWO to build a facility that makes controlled, thin layers of material. The facility can produce small and large films, something that is globally unique. And that is key to scaling up, for example, new catalysts…

She develops algorithms that outperform leading optimization techniques and can be applied in many fields. For this work, Niki van Stein and her team have won the GECCO Humies Award. ‘With our method, we can create and refine algorithms for a wide range of applications—algorithms that are better than…

Seven hundred and three independent student flats will be built in the entrance area of the Leiden Bio Science Park (LBSP), close to the University Sports Centre. Construction will begin this year and the accommodation is expected to be completed by the start of academic year 2023-2024.

On Tuesday evening 22 August, our very dear colleague Jo Hermans passed away. Jo had been ill for some time, but continued to enjoy life in good spirits until the very end. He meant a great deal to Leiden University and will be remembered with fond memories by many.

Since 1 November 2025, Prof. Dr. Luc Sels has been the new president of Leiden University's Executive Board. In a message to our university he introduces himself and shares his first impressions.

In consultation with the Executive Board of the Faculty of Social and Behavioural Sciences and having heard the views of the Faculty Council, the Executive Board has appointed Bart Barendregt as Dean of the Faculty until 1 April 2027.

A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

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…

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Assistant professor Joost Willemse firmly believes that as a teacher, you’re never done learning. ‘Students ask questions about things you’ve never thought of yourself. Ultimately, that makes you better at your job.’ That’s why he always encourages his students to ask questions. And it’s appreciated:…

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

Five Leiden researchers have been awarded a Consolidator Grant by the European Research Council (ERC). This grant of up to two million euros will enable them to continue and expand their scientific research.

A pandemic of lianas is sweeping through tropical forests, reducing their ability to store carbon and limiting their role in mitigating climate change. Two recent studies from Leiden University highlight the issue. ‘We now understand why lianas are visible in satellite imagery.’

How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

How do biological cells join forces to form a structure? In her PhD research, Daphne Nesenberend uses mathematics to show how forces and cooperation between cells create structure – and how simulations and experiments can reinforce each other.

Leiden researchers have discovered a surprising new way to shape and control tiny droplets of molecules found in living organisms. The breakthrough could lead to smarter biomaterials, improve drug delivery and even new insights into the emergence of life on Earth. The work was published in Nature Co…

How do you detect life on a planet light years away? During her PhD research, astronomer Willeke Mulder worked on an instrument to detect such signals – culminating in an experiment from a hot air balloon.

NATO not only safeguards our security and stability, but also defends Enlightenment principles, promoting prosperity, health and freedom. This is what eminent psychologist and thinker Steven Pinker argued to a packed Great Auditorium.

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…
