Hieratic Papyrology

The project GRADIENTS investigates what it meant to be European in colonial Africa where identification as European often did not depend on skin colour and was understood on a spectrum with many gradients.

Research in the History and International Studies 1900-present specialisation addresses the interconnectedness and interdependence of contemporary global political, economic and cultural developments from a multidisciplinary perspective which is rooted in the humanities.

Lecture, Unfolding Finitudes

The Colonial and Global History Research Programme of the Leiden University Institute for History combines a deep curiosity of transcultural processes such as imperialism, (de)colonization, and globalization with critical historical research on regional societies in Africa, Asia, and the Americas.

Five Leiden astronomers tell about science in the podcast Astronomy et al. This podcast was set up by Ricardo Garcia Soto in September 2016 and is focused on anyone who is interested in science.

The map application includes information from old and new buildings archaeological projects. This makes it possible to investigate whether water facilities (wells, cisterns) and waste facilities (cesspits, sewers) were the privilege of Leiden’s wealthy elite in the late 16th and 17th centuries or whether…

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.

Three cholera epidemics struck 19th-century Leiden. Today’s corona epidemic prompted Martijn Storms, curator of maps and atlases at the Leiden University Libraries, to scour the library for maps about these past epidemics.

If three or more objects move around each other, history cannot be reversed. That is the conclusion of an international team of researchers based on computer simulations of three black holes orbiting each other. The researchers, led by the Dutch astronomer Tjarda Boekholt, publish their findings in…

After 25 years, December will finally see the launch of the long-awaited James Webb space telescope. Leiden astronomers are watching with great excitement: not only were they involved in the construction of important instruments on board, the telescope will also reveal many new secrets of the universe,…

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Anthropologist Rodrigo Ochigame studies how AI is changing the practice of scientific research. From astrophysics to mathematics to climate science, they find that the adoption of new AI models is raising questions about what counts as reliable scientific evidence.

The excuses for the slavery past? It would have been better if the cabinet had taken some more time on that, thinks university lecturer and Atlantic slavery expert Karwan Fatah-Black. 'Too bad they didn’t wait for the results of the study.'

From research on stellar winds to sign language: an impressive seven researchers from Leiden University will receive a prestigious Vici grant from the Dutch Research Council (NWO).

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

Afro-American slaves in the 19th century did not always flee to the north of the United States, according to historical research. Most of the slaves who fled remained in the southern states and posed as free coloured people. This is the conclusion that Professor Damian Pargas from Leiden University…

The New Scientist magazine has selected two young Leiden scientists for its Top 25 Young Talents in the Netherlands and Flanders: historian Karwan Fatah-Black and neuropsychologist Mariska Kret. Who will be the winner? You can vote for one of them!

The skin has recently gained attention within body studies for its many specific cultural and social associations, in addition to its biology. This project aims to examine the different layers of meaning and the functions invested in the skin in ancient Greece: how did ancient Greek literary and medical…

Regulating Relations: Controlling Sex and Marriage

From 15 augustus 2014 onward, Leonor Álvarez Francés is appointed as PhD student on Raymond Fagels NWO project ‘Facing the Enemy. The Spanish Army Commanders during the First Decade of the Dutch Revolt (1567-1577)’

Ruling Overseas: Connected Practices of Governance of Law

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

The Old Obervatory Leiden is one of the partners of the local learning ecosystem ‘Verwonder om de Hoek’, an educational platform from Leiden that lets school children and families wonder about the world of Nature, Science, Technology and Sustainability. On this page you will find the educational programmes…

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Simulations of galaxies help researchers understand astronomical observations better. The EAGLE simulation, a large project in which Leiden astronomers play a leading role, shows the evolution of the Universe, from just after the Big Bang to the present day.

The quest for Trustworthy AI is high on both the political and the research agenda, and it actually constitutes TAILOR’s first research objective (H1) of developing the foundations for Trustworthy AI. It is concerned with designing and developing AI systems that incorporate the safeguards that make…

Lyndsey Housden teaches in the Interactive/Media/Design department at the Royal Academy of Art (KABK), The Hague. She is a researcher and artist, working with interactive and haptic installations, spatial design and interdisciplinary projects for exhibitions, theatre, and festivals.

Cities, Migration and Global Interdependence focuses on inequality in all its forms. You will approach this subject from an intersectional perspective. Since categories of power and identity are always intertwined, the courses in the programme reflect this reality. This means you will study how societies…

The Mapping Slavery project will place markers that tell the story of Leiden’s slavery past. Why is this important and what does it mean for today’s society? Before the markers are placed, a panel came together on 24 March to discuss the slavery past of not only the city but the University too.

Ijeoma Uchegbu is Professor of Pharmacy at University College London (UCL). As a female scientist of colour, she was initially reluctant to play an active role in the university’s diversity policy. Until, that is, she had a radical change of heart: ‘I knew it; I had to become an evangelist.'

The Caribbean as we know it today is fundamentally a product of colonial activity and globalisation. Practically everyone that inhabits the Caribbean has ancestors from different continents due to colonial activity, which profoundly affects the area to this day. Caribbean writers, both in the Caribbean…

Salt crystals, a nano-sized golf stick and molten glass. The LION Image Award competition of 2023 yielded a lot of beautiful images once again. But in the end, only one can be the winner.

Media all around the world reported about it: the most detailed images yet seen of galaxies, shot by radio telescope LOFAR. The international team behind these amazing results were led by Leah Morabito at Durham University and included three talented Leiden astronomers.

After almost twenty years the record for the most distant radio galaxy has been broken. A team of astronomers led by Leiden PhD candidate Aayush Saxena has discovered a radio galaxy from the time when the universe was just one billion years old. The galaxy is at a distance of 12 billion light years…
