We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

Enabling volume-restricted metabolomics using next-generation microscale analytical tools.

On this page, you will find the recordings of the online This Week's Discoveries from May 12, 2020, as well as a list of speakers since October 2015.

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently, more than 8000 people are working and studying at the eight institutes.

The research of the Mathematical Institute is driven by the curiosity of its members and has many internal and external connections. It can be characterised as fundamental but with an open attitude towards applications.

The central theme of the NWO-project ‘The Promise of Organization’ is the evolution of political organization during the 19th century. We focus on the enthusiasm, arguments and concrete activities of the organizers as well as the criticism offered by opponents of modern political organization.

The Cleveringa chair was installed by Leiden University in memory of Professor Rudolph Pabus Cleveringa and the courage he demonstrated in November 1940 during the German occupation . It also commemorates the liberation of the Netherlands in 1945.

One of the stained glass windows in the Great Auditorium of the Academy Building is dedicated to the students and staff of Leiden University who resisted, protested against, or became victims of the German occupiers. It depicts female figures alongside male ones.

The chief aim of this study is to explore how classical Persian poetry and the Persian mysticism that is interwoven with the poetry have been used in the new politics of the Islamic Republic of Iran, especially during the Iran-Iraq war.

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

By measuring proteins in tears, ophthalmologists can more easily diagnose dry eyes (Dry Eye Disease). Peter Raus, a Belgian ophthalmologist and PhD student at the Institute of Biology Leiden, developed a new method for protein determination in tear fluid. The technique is also promising for the early…

In this penetrating self-portrait dating from around 1629, Rembrandt presents himself as an aristocratic young man. He enrolled in Leiden University as a student of the arts in 1620, but whether he actually attended lectures is unknown. In his paintings and prints, he incorporated many topics that are…

How to make a quantitative assessment of the relative contribution to toxicity of ions and particles? Is the toxicity of nanoparticles related to their size or shape? Which physicochemical property of nanoparticles is an appropriate dose metric of nanoparticles?

The Global Abolitionisms Network, established in 2015, is an international network of scholars working on antislavery activism and abolitionism. It is affiliated to the Leiden Slavery Studies Association.

This thesis is about cosmological inflation and its relation to observations.

Semantics and pragmatics are united in the study of linguistic meaning.

The field of science communication is very broad. Below is a list of organisations where SCS students can fulfill internships or where alumni have found jobs.

This book is the first to incorporate current academic literature and case law on European, transnational, and international media law into a comprehensive overview intended primarily for students.

In this thesis we study products of linear error correcting codes.

We are developing biology-driven platforms to measure metabolites based on liquid chromatography-mass spectrometry (LC-MS), gas chromatography-MS (GC-MS), and capillary electrophoresis-MS (CE-MS).

Narrative Science examines the use of narrative in scientific research over the last two centuries.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

From the 1920s on, popular music in Southeast Asia was a mass-audience phenomenon that drew new connections between indigenous musical styles and contemporary genres from elsewhere to create new, hybrid forms. This book presents a cultural history of modern Southeast Asia from the vantage point of popular…

Joseph Callingham from the Leiden Observatory receives the Louise Webster Prize for outstanding post-doctoral research. The prize is awarded by the Astronomical Society of Australia for Callingham’s search for the most extreme object in the Universe.

The European Space Agency (ESA) has published an interim data release from Gaia, the space telescope mapping out the Milky Way in 3D. The first scientific papers published today reveal half a million stars in the Omega Centauri globular cluster, nearly 400 candidate gravitational lensers and the positions…

Tim Koopmans is one of the great minds in the history of Dutch and European legal scholarship. He taught law as a professor in Leiden and other universities, among which Ghent, Cambridge, Utrecht. He practiced it as a judge in the European Court of Justice and Advocate-General in the Dutch Supreme Court,…

At the initiative and expense of His Royal Highness King Willem-Alexander, Leiden University will be conducting a study of the role of the House of Orange-Nassau in Dutch colonial history. The project will run from 2023 to 2026.

The Biomedical Microscale Analytics group is led by Dr. Rawi Ramautar. In present-day metabolomics, and bioanalysis in general, the analytical toolbox used encounters difficulties for the analysis of limited amounts of biological samples. As a result, a significant number of crucial biomedical/clinical…

How do nanoparticles bioaccumulate and biodistribute in organisms?

Lecture

This research cluster is a part of the Institute of Political Science’s research programme ‘Institutions, Decisions and Collective Behaviour’. Its members focus on the democratic role of citizens and the representative links between voters and politicians.

Jed Wentz realized a unique concept: 19-th century melodramas for voice and piano.
