The whole world is waiting anxiously for sufficient supplies of coronavirus vaccines. As Launch Navigator at Pfizer, alumnus Dennis de Mik must help ensure that the Netherlands receives 19.8 million doses of the Pfizer/BioNTech vaccine. How is he going about this and how has his Bio-Pharmaceutical Sciences…

It poured down when Alexander Gallo received his diploma from West Point Military Academy. A bad sign, people said back then. It was June 2001, three months before 9/11. The now 46-year-old American fought in Iraq, did research in Afghanistan and stands in Leiden today, defending his dissertation on…

Within a single generation, the digital world has changed completely: from a technical niche for ‘nerds’ to a reality that affects everyone. Cyberattacks, data breaches and system failures can disrupt essential social processes. How can we ensure that our society remains digitally resilient?

Two Leiden researchers have been awarded ERC Proof of Concept grants. These grants, each worth EUR 150,000, will help the grantees in their efforts to bridge the gap from basic science to real-life applications

How ethical is research involving humans and robots? And can research on artificial intelligence cause problems when it ends up in the wrong hands? In any research involving humans or their data, the ethics committee assesses where the issues are. Associate professor at LIACS Suzan Verberne chairs the…

Proton therapy is a new way of treating cancer in which radiation doses are delivered more precisely. This results in less damage to surrounding tissue and fewer side effects. Professor Marco van Vulpen is medical director of HollandPTC in Delft, where the social value of this therapy is studied. Van…

What’s really happening in the space between the cells in your body? With the Collagen Canvas project, students from Leiden University invite you to explore this question by blending science with art. This interactive artwork immerses you in the dynamics of the extracellular matrix—the invisible structure…

Students gain practical experience while clients receive a solution to their software needs: the student software company LUdev hits two birds with one stone. ‘Through LUdev, students learn what else is involved in software development besides programming.’ Interested? You can now submit new projects…

A special type of mirror to reflect X-rays has more possible applications than space research. Targeted radiation therapy for cancer, for example. Next to his full-time job, physicist David Girou mapped out the possibilities. He will receive his PhD on 14 June.

Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…

A breakthrough from the PhD research of medical chemist Elmer Maurits may help patients with autoimmune diseases and blood cancer in the future. But bringing a discovery from the lab to the clinic is not so easily done. Thanks to NWO's Venture Challenge, Maurits and his team will receive ten weeks of…

Various thought-provoking questions have been appearing online and in print adverts. They are part of a national university funds campaign in which the Leiden University Fund (LUF) is also participating. We wanted to find out more, so we called LUF Director, Lilian Visscher.

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…

On October 12th, the LACDR PhD-Postdoc event will be organized in castle Oud Poelgeest.

On February 28th of this year Dr. Andrzej Tadeusz Antczak died of cancer after a long battle. Until his retirement in 2023 Andrzej was attached to the Faculty of Archaeology as an Associate Professor in Caribbean Archaeology. From 2017 until 2020 he was the Head of the Department of World Archaeology,…

With the passing of Stephen Haigh on 9 September 2022, Leiden University's Institute of Political Science has lost a dedicated and inspiring instructor.

On World DNA Day 25 April, Leiden University is pleased to focus the spotlight on Rosalind Franklin, whose name was given earlier this month to the Campus Square on the Leiden Bio Science Park. This square will now be known officially as the Rosalind Franklin Square.

From medicines from snake venom to supercrops and the origin of words. Thirteen researchers from Leiden University will receive Open Competition XS grants from the Dutch Research Council (NWO).

Nearly 19,000 runners lined up at the start of Leiden Marathon on Sunday, among them students and staff from the university. For some this was their first race, for others a highlight of their year. This year, in celebration of our 450th anniversary, they ran in a special jubilee t-shirt.

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

PhD candidate Daniël Gomon has developed statistical methods that could significantly improve research in fields like medicine and demography. ‘Mathematicians don’t like unrealistic assumptions,’ he says. Gomon will defend his PhD thesis on 19 June.

Developing new drugs is a difficult process. With the aid of artificial intelligence, Pharmaceutical scientist Xuhan Liu has developed methods that can help make drug design cheaper and faster. PhD defence on 15 February.

How can Europe lead the way in vaccine development that is fast and for all? To answer this pressing question, Professor of Vaccinology Meta Roestenberg is holding a panel session on 14 July at the EuroScience Open Forum in Leiden.

On 15 April, our much-beloved and highly respected former colleague Dr Hans Brussee passed away from cancer. In January 2025, Hans began experiencing neck pain. Initially, it appeared to be a herniated disc, but sadly, the diagnosis was soon revised, and his condition proved untreatable. Hans was 77…
