How do atoms and molecules end up forming planets? That's what astrochemist Julia Santos studied during her PhD. She discovered the dominant process behind the formation of methanol in space – a finding that surprised the entire field.

When deciding what to study you undoubtedly read a lot of information about your study programme. Leiden University employs various systems to provide information about programmes and courses and to facilitate communication between lecturers and students.

Sense Jan van der Molen is vanaf 1 maart de nieuwe wetenschappelijk directeur van het Leiden Instituut voor Onderzoek in de Natuurkunde.

Without electronics carrying out computational tasks our daily lives would look very different. Devices such as elevators, vending machines, turnstiles, washing machines and even traffic lights use a simple form of electronic computing to switch from state to state. But, what if power supply is not…

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

How can we tell whether and how a prehistoric weapon was used? How can we better understand the dexterity and combat skills involved in Bronze Age spear fighting? A research team from Leiden and Göttingen University present a new approach to answering these questions: they simulated the actual fight…

Leiden students often prefer complicated theory and a difficult test to experiments. Yet associate professor Paul Logman believes students learn a lot from practical teaching. He challenges his students to come up with their research questions themselves. The Leiden Institute of Physics (LION) is at…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

As a bachelor’s student at Leiden University, you will be issued with binding study advice (BSA). This means you must obtain sufficient study credits in the first year of your bachelor’s programme to be permitted to continue studying. Some programmes also have additional requirements.

Physicist Remko Fermin from Leiden University was awarded a Rubicon grant from NWO. He will use it to study superconducting diodes that could contribute to reducing the CO2 emission of data centres.

A study association is a good way to combine study-related activities with pleasure. Every faculty has one or more study association.

Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…

Martin van Hecke and Lennard Kwakernaak (Leiden university and AMOLF) develop a mechanical metamterial that can count to ten in their research.

Hoping to learn something about the human brain, Leiden researchers are creating a setup to shoot single photons, particles of light, into someone’s eye. ‘The eye is a passageway to the brain.’

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…

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.

White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

An all-optical transistor, a molecule-sized sensor and a new kind of single-photon source for quantum communication. All dreamed applications of fundamental physics that are one step closer thanks to Robert Smit. On 12 June, he defended his PhD thesis with distinction.

Data Science & AI student Nataliia Bagan combines a passion for mathematics, language, and artificial intelligence. Her exceptional bachelor’s thesis on improving reasoning in large language models earned her a nomination for the Leiden Science Young Talent Award 2025.

Cancer research generates massive amounts of data, but traditional tools often fail to fully harness their potential. How can we unlock this data to provide better treatments for cancer patients? PhD candidate Marina Gorostiola González explored this by using advanced data analysis techniques to guide…
