Rainbow flags, funky sounds and drag queen Petty Libel: the very first Canal Pride Leiden has become reality. Leiden University joined the parade with a packed and buzzing boat. ‘The Leideners were really supportive and gave us a great response.’

This project applies a social-historical approach to examine and contrast various groups of African-American slave refugees who sought freedom within North America between 1800 and 1860. It innovatively distinguishes between different “spaces of freedom” for runaway slaves, namely sites of formal, semi-formal,…

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Piercing through the skull with an ice pick, administering electric shocks without an anaesthetic, or applying leeches to the uterus: these may seem like medieval methods of torture, but they are in fact therapies used in medicine. Willem van der Does writes about all of them in his new book. ‘Physicians…

In the South African context, certain iconic images have been a dominant source for public understandings of historical events. The emphasis given these images tends to overshadow the historical value of other more personal photographic sources – like studio or amateur photography. This project looks…

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Get to know us through our online and in-person events for prospective students!

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

So far it has been impossible to compare large sets of syntactic constructions in large sets of languages systematically and automatically. The online availability of parallel text corpora and software tools to align, enrich, search and analyse them has the potential to make automatic massive systematic…

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

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.

Macrophages and atherosclerotic lesions The infiltration of monocytes in the arterial wall, their differentiation to macrophages, and the subsequent accumulation of cholesterol in these macrophages initiate the process of atherosclerosis. We study the importance of specific genes in macrophages for…

Hoe kijken Nederlandse bedrijven naar online prijsdiscriminatie? Kimia Heidary, Bart Custers, Helen Pluut en Jean-Pierre van der Rest schreven hier een artikel over.

On Thursday 27 June, the last festive ILS Lunch Seminar of this academic year takes place. This seminar will feature presentations from two distinguished speakers from different departments of Leiden Law School: Prof. Pablo Mendes de Leon and Albert van Marwijk Kooy.

The Cide Archaeological Project: Surveying the Turkish Western Black Sea Region

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Elk jaar organiseert het LIBC in samenwerking met de gemeente Leiden een Publieksdag over hersenonderzoek.

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

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.

The main interest of this project concerns learners’ perceived learning outcomes in massive open online courses and the factors related to their perceived learning outcomes.

In the master’s programme in Archaeology, you can follow courses on the archaeology of Europe, deepening your understanding of the continent’s long history.

an integrated, secure, permanent, on-demand service-driven, privacy-compliant and sustainable e-infrastructure for the processing, analysis and information-mining of the massive amount of medical molecular phenotyping and genotyping data that will be generated by metabolomics applications now entering…

Existing work in probabilistic language modeling can be mostly divided into two categories:

The Summer School in Languages and Linguistics has been a regular event on the Leiden Centre for Linguistics calendar for over 14 years.

We aim to develop a drug-delivery method based on the production of biomolecules directly at the target site.

The Master Honours Classes & Challenges are part of Leiden’s honours education for master’s students. While the Honours Academy is responsible for the practical organisation, the education is coordinated by teachers of all faculties.

De Nederlandse geschiedenis is nauw verbonden met die van de wereld als geheel. Door migratie, handel en kennisuitwisseling beïnvloedden mensen elkaar over grotere afstanden en intensiever dan we lang dachten. Wereldgeschiedenis van Nederland toonde in meer dan honderd verhalen hoe internationaal de…

De minor Data Science & Artificial Intelligence geeft een toegankelijke introductie tot de theorie en praktijk van datawetenschap en kunstmatige intelligentie. Studenten leren de basis van data-analyse en patroonherkenning in grote gegevensverzamelingen, hoe computers leren en ook het interpreteren…

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Humanities with Anton de Kom University in Suriname.

This volume considers the military architecture and its impact on local communities in Rome's eastern frontier, which stretched from the north-east shore of the Black Sea to the Red Sea.

On behalf of the Dutch astronomical community, we unequivocally condemn the brutal killings of Ahmaud Arbery, George Floyd, and Breonna Taylor and countless others and instances of racism.

This dissertation is a study of archaeological remains left behind by nomadic communities in the Black Desert, situated in the northeast of modern Jordan.
