Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

Do you have a question concerning the Bachelor Honours Classes (BHC’s)? You can find the answers to the most Frequently Asked Questions below.

PhD candidate Joeri Schoenmakers works at the LIC and describes how his days revolve around new experiments, oxygen-free reactions and supervising students. The mix of freedom, variety and a close-knit team means he enjoys both his research and his teaching role every single day.

It was already the most cited publication ever written at our faculty, but now a new milestone has been reached. Last month, a paper by emeritus professor Jan Reedijk and his co-authors surpassed 10,000 citations — and the count keeps rising.

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

Op de dag van de duurzaamheid van 10 oktober startte de 'Billiecup' pre-pilot op de Faculteit der Rechtsgeleerdheid. Aanwezig waren 'plastic soup surfer' Merijn Tinga, Bart Hemmes van het Leiden University Green Office (LUGO) en Esther Kentin, docent bij instituut Metajuridica & projectleider Leiden…

Sander van Kasteren (Professor of Molecular Immunology) makes the invisible visible. He will explain more in his inaugural lecture.

Mahatma Gandhi’s quote “Be the change you wish to see in this world” was taken quite literally by some of our BA International Studies students, as they set up their own NGO, Positive Debt, in cooperation with students from Kyambogo University in Uganda. The NGO helps single mothers in Uganda with m…

Cramming from a book, making notes or learning summaries. In the past these were about the only ways to memorise your course material. But that has long since changed. Multimedia is the code word. But is it effective?

For over a year now, the James Webb Telescope has been sending stunning images that exceed astronomers’ expectations. The photos are fascinating to see, but what exactly are we looking at? Assistant professor Melissa McClure explains.

Seven Leiden professors have been elected as members of the Royal Netherlands Academy of Arts and Sciences (KNAW). In total 23 new members will be inaugurated on Monday 13 September.

Researcher Daan van der Vliet, together with colleagues from the Netherlands Institute for Neuroscience, Leiden University and Utrecht University, has discovered an important mechanism that may be linked to severe cases of multiple sclerosis (MS): the brain contains large numbers of abnormal immune…

Over the coming years, LUCL will be collaborating on the development of Macroscope, a new scientific infrastructure that maps social change at the population level. Professors Gijsbert Rutten, Stephan Raaijmakers and Carole Tiberius tell us more about the project.

Yeast, alpacas, and antibodies. They may seem unrelated, but within the project of the Leiden iGEM students, they come together perfectly. For the international synthetic biology competition iGEM, the team is working on an innovative method to produce nanobodies—a special form of antibodies—using brewer’s…

To increase the accuracy of climate models, it is crucial that they include past human land-use and human-driven vegetation changes. Here archaeology can make an important contribution. Current models are based on reconstructions of past vegetation. However, their accuracy is limited because it does…

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

How do you engage students? Sander van Kasteren knows how to do that like no other. ‘He compares immune cells to Pokémon and doesn’t just give information; he tells stories,’ students say about their favourite lecturer, Sander van Kasteren. The Professor of Molecular Immunology passionately teaches…

Smart drug carriers, uneven cosmic expansion, and solar energy storage in molecules. These are the topics of three newly awarded NWO-XS grants to researchers at the Faculty of Science.

Leiden researchers, led by Sebastian Pomplun developed a new method to screen hundreds of thousands of molecules for drug discovery, using mass spectrometry instead of DNA tags. ‘We wanted to make drug discovery faster and more accessible.’

From 1 October, two new Directors of Education will start at the Institute of Biology Leiden (IBL). Dennis Claessen as the new director for the master's programme of Biology and Marcel Schaaf as director for the Biology bachelor's programme. Claessen and Schaaf have been appointed for a period of four…

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

The newly launched Public Leadership in Collaboration partnership has been designed to enhance leadership within and across public sector organisations through research. This kind of leadership has a direct impact on society. Professor Ben Kuipers from the Leiden Leadership Centre (LLC) shares three…

Do you want to request a change to the academic requirements set by your bachelor's or master's programme? Perhaps you want to be exempted from a particular course, because you think you have already acquired the knowledge elsewhere. Or do you want academic credits earned at another institution to be…

For months, students dedicated themselves to a more sustainable world alongside their studies, as part of the LDE Sustainability Honours Programme. What solutions did they come up with for the challenges posed by organisations like Naturalis and ClimateMatters?

Researchers at Leiden University have created a unique model that mimics how disease develops after a dengue infection. This 'dengue-on-a-chip' model helps them study the virus more effectively. The timing is crucial, as climate change is causing dengue to spread worldwide.

‘If it rains later, then I’ll take the car.’ In order to reason, we use sentences containing ‘if’ every single day. But how does that work exactly in the Dutch language? Alex Reuneker wrote his 628 page dissertation on the subject. Ceremony on 26 January.

A suitcase covered with stickers from various universities, containing a quantum light source. Since April 2024, this suitcase has been visiting scientists in Europe researching single photons: the smallest possible quantity of light. The suitcase, also called ‘Q-torch’, travels from lab to lab like…

As from April 2023 all students at Leiden University, Delft University of Technology and Erasmus University Rotterdam will start using the eduXchange portal to register for a minor.

Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

Two research groups involving Leiden University have been awarded a major European grant, the ERC Synergy Grant. This for research on the development of membranes that can clean water and purify medical drugs and research on the biological clock in certain bacteria.

Opening van het Quantum Delta NL (QDNL) Talent & Learning Centre (TLC) Leiden-Delft.

Researchers at the Universities of Amsterdam (Uva) and Leiden together with the Netherlands Cancer Institute and Oncode Institute have received a €10,6 million ERC Synergy Grant to develop innovative therapeutic approaches to target glioblastoma. This is a deadly primary brain tumour for which no curing…

Is it a coincidence that three chemists from the same department have each independently received a ZonMw grant? 'No,' the researchers agree in unison. 'The role of chemistry in medical biology is becoming increasingly important, and we’ve worked hard to make this happen.'

What happens in the brains of people with psychiatric illnesses? With a €23.23 million gravity grant, scientists from different fields will search for biological causes over the next decade. ‘By joining forces, we hope to improve diagnosis and treatment for patients with these diseases.’
