The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration…

The focus of the research lies in the approach of reducing, denying, or taking away essential elements of music making in order to let the musician become theatrical.

LUCIS is directed by Nathal Dessing, who is advised by a steering committee.

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

Electron microscopy has become an extremely important techniquein a wide variety of elds.

RoRI was founded in 2019 by a group of researchers, funders and data providers with a mission to accelerate transformative research on research systems, cultures and decision-making. CWTS is proud to be a core partner from the very beginning.

This UNESCO Chair at CWTS aims to contribute to UNESCO’s agenda to foster diversity and inclusion in science. The chair has two main lines of work:

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

What is the difference between highly visible and poorly visible monuments on the alignment? And is this difference reflected in the social position of the dead buried underneath these mounds.

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

Michel Orrit has received an NWO-TTW Open Technology Programme grant. He will use it to image single molecules without the need for fluorescence.

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

This research sets out to answer the following questions:

On 12 November 2019, Larissa Koupriuchina defended her thesis 'Judgmental Adjustments in Revenue Management'. The doctoral research was supervised by Prof. J.I. Van der Rest.

The data-driven economy allows for the collection and processing of large amounts of data. Such data can be used to optimize profits by (dynamically) differentiating prices for different consumers.

Dr. Joris Larik, Assistant Professor of Comparative, EU and International Law at LUC The Hague, has co-authored a report entitled 'UN 2.0: Ten Innovations for Global Governance 75 Years beyond San Francisco'.

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

As of November 1st 2019, Sybille Lammes, Professor of New Media and Digital Culture, will be the new academic director of the Leiden University Centre for the Arts in Society (LUCAS). She succeeds Anthonya Visser, who has been the institute's academic director since 2014. It is a three year-long appointment.…

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

On July 8 and 9, 2022, Leiden University hosted the second conference of the research group on Institutions for Conflict Resolution, in collaboration with Radboud University Nijmegen and Utrecht University.

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

Leiden University is developing new short stay living space for foreign guests and employees. De Kloksteeg is currently the last of four projects that has been renovated by the Leiden University Real Estate directorate since 2017. The Service Centre International Staff (SCIS) is responsible for rental…

Music profession requires strong reflective, collaborative, creative and improvisational skills, yet prevailing one-to-one tuition in conservatoire education focuses mainly on transmission of craft skills. Examining effects of students' collaborative and experiential learning, as in learning labs, creates…

The American president Trump is considering military intervention in Mexico to get rid of the drug cartels once and for all, but Mexico is not interested in other countries' interventions. According to Jelle van Buuren, Assistant Professor at the Institute of Security and Global Affairs, Trump's much…

Michel Orrit was awarded the Physica prize 2016 for his groundbreaking work on single molecule spectroscopy.

Visualising cell proteins without invasive techniques is possible with the help of fluorescence. During a lecture of the Natuurwetenschappelijk Gezelschap Leiden on 18 January, winner of the Spinoza Prize 2017 and founder of the field of single molecule optics Michel Orrit explained how this works.

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

On September 12, Michel Orrit received his Spinoza prize in the Royal Theatre in The Hague from OCW Secretary of State Sander Dekker. With the award comes a budget of 2.5 million euro, to be spent freely on scientific research, and the coveted Spinoza statue. Orrit shared the honor with Eveline Crone…

Physics and Engineering Approaches to Biomedicine and Pharmacology

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

The CIGR comprises research groups from the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

We are pleased to invite abstracts for a conference on ‘Advancing Social, Economic, and Cultural Rights in a Polarised, Digitalised, and Unequal World’ to be held at Leiden University on 4 and 5 September 2025, in collaboration with Netherlands Network for Human Rights Researh (NNHRR).

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

In the first part of this thesis we study the geometry of folding patterns.

We study the dynamics of individual emitters in micro cavities.

On 8 October, an inspiring session was held at the KOG Building.
