On 8 February 2016 prof. Jennifer Chayes received her Honorary Doctorate at Leiden University as part of the 441e Dies Natalis. A video registration of this special event has now been published. For the ceremony of Jennifer Chayes’ Honorary Doctorate, please scroll to the 82th minute.

You can't have missed it: Leiden University celebrated its 444th anniversary in 2019 with a year-long programme of activities for the people of Leiden and The Hague. The Dies Natalis on 7 February 2020 marks the end of this special year. High time to look back at what we did!

On 11 and 12 December, the Associazione Italiana di Filologia Germanica (AIFG) organizes a graduate conference around the theme of "The Fantastic and the Supernatural in the Medieval Germanic Traditions". PhD students and recent graduates who wish to present are encouraged to submit an abstract before…

Since 2000 the Leiden Student Council (LSR) yearly awards a prize for the best teacher of the university at the Dies Natalis.

On 18 January 2020 Christa Tobler took part in a fireside talk on the above-mentioned topic, together with European Parliamentarian Andreas Schwab, Swiss Parliamentarian Eric Nussbaumer and German Ambassador to Switzerland Riedel.

Each year on the university’s birthday, children at primary schools in Leiden and The Hague have a lesson from a professor – about children’s rights and robots in surgery, for example. The children get to do activities. And ask questions: ‘How do you become a professor?’

Leiden University is celebrating its 450th anniversary in 2025 with a feast for the eyes, ears and spirit. The anniversary year opens with an extra special Dies Natalis on 7 February. Highlights includes an alumni festival, three exhibitions and a canal concert.

Making sensitive data reusable through synthetic data generation

The Aesernia Colonial Landscape project investigates ancient settlement patterns and dynamics around modern Isernia in Molise (Italy), the Latin colony of Aesernia (founded 263 BC). It consists of intensive systematic field survey in the territory of the colony, combined with remote sensing and geoprospection…

The goal of the ANASTASIS project is the analysis and publication of early medieval (Merovingian) cemeteries in the Netherlands (c. 500 – 750 AD).

Bones hold a wealth of information about a person’s life, revealing details about where they came from, how old they were when they died and what diseases they may have had. Scientists can use this data to piece together aspects of an individual's life, offering valuable insights that can help address…

In this research group, led by Dr. Joost Beltman, the aim is to employ mathematical and computational dynamical modelling approaches in order to quantitatively and mechanistically understand the dynamical behaviour and regulation of intracellular networks of genes, proteins and metabolites as well as…

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

The CADS Research Cluster People, Power and Diversity aims to further theoretical and methodological debates on the classifications of human difference, such as gender, race, ethnicity, sexuality, class, age, ability, religion, level of development, time, etc., and the way these classifications organize…

Studies on the Disappearance of the Amphora Phenomenon

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

Orange the World 2025

Mazatec chants and ancient Mesoamerican pictography

Research on this theme concerns Europe’s position in global markets, its response to the emergence of new international trade and financial actors that challenge institutions where Europe has long had considerable influence.

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.
