This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

People come to court because of a legal dispute, and often think that the court decision will also resolve the underlying conflict. But that is not always the case. ‘Court decisions should provide a better response to the needs and the nature of citizens,’ argues professor by special appointment Rogier…

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology. This has been announced at the presentation of the honoured proposals in The Hague…

Vedran Dunjko appointed to full professor of quantum computing at Leiden University, the Netherlands.

The Europa Institute of Leiden University is one of the oldest academic institutes specialised in the law of the European Union and the European Convention on Human Rights; it was established in 1957, the same year as the European Economic Community itself.

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

Last week, on 13 February 2019, the EU approved the ban on pulse trawling. This followed the vote for a ban by the European Parliament on 16 January 2018. Half of the 84 Dutch pulse trawling vessels must stop immediately; the other half will receive a transitional arrangement until July 2021. Outcomes…

The more than 370 sensors that have been hung up in Leiden University buildings to count the people present will not be switched on again. The equipment will eventually be removed from the buildings.

Natural Computing investigates algorithms and phenonema based on nature to create better and new computer science innovations.

By comparing individual health data with population data, doctors can provide personalized health advice and patients can learn from each other's experiences. Wessel Kraaij, professor of Applied Data Analytics shows how personal data can have predictive value.

How does the social infrastructure affect administrative burdens associated with digital government services? The paper 'Administrative burden in digital public service delivery: The social infrastructure of library programs for e-inclusion' published in the Review of Policy Research by Sarah Giest…

The ability to collect and interpret huge quantities of data has become indispensable to society and academia. Leiden University is a knowledge and expertise centre for data science that places the emphasis on interdisciplinary collaboration and innovation.

Politicians' statements often involve emotions, shaping public perceptions. This study highlights the role of emotions in EU foreign policy.

How public service motivation and professionalism affect decision-making in dilemma situations. Individuals who work in the public sector see themselves confronted with conflicting values, contradictory demands, and the need to serve an at times difficult to define ‘public interest’.

To what extent is the legislation and use of pre-trial detention of juveniles in the Netherlands in compliance with international children’s rights standards?

Lions limit their prey, such as zebra and gnu, in their options for adapting to global warming. This is what Leiden researcher Michiel Veldhuis, from the Institute of Environmental Sciences, and a group of international colleagues have discovered. The research was published today in Nature Ecology &…

In this project we develop algorithms to automatically detect a particular type of archaeological sites in satellite images of the Alps.

Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

NimbleAI aims at solutions for ultra-energy efficient and secure neuromorphic sensing and processing at the edge.

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology.

The Leiden Computational Network Science Lab (CNS Lab) researches methods for knowledge discovery from real-world network data.

Viral diseases constitute one of the major challenges in modern medicine. Membrane-targeting have broad-spectrum potential and could distinguish viral membranes from the host cell plasma membrane by the difference in membrane curvature.

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

Quantum annealing belongs to a family of quantum optimization algorithms designed to solve combinatorial optimization problems using programmable quantum hardware. In this thesis, various methods are developed and tested to understand how to formulate combinatorial optimization problems for quantum…

The Reinforcement Learning lab conducts research into Reinforcement Learning and Intelligent Combinatorial Algorithms.

Het strategisch plan van de faculteit wiskunde en natuurwetenschappen (FWN) werd gepresenteerd tijdens de opening van het academisch jaar 2023-2024.

No less than six Leiden projects received a grant for quantum research from the national growth programme Quantum Delta NL and the NWO. After all, in order to boost quantum technology not only industry is needed, but also science. Research towards new sensors, faster algorithms and quantum materials,…

Here you can find the recordings of previous Florence Nightingale Colloquia.

Intelligent machines are going to make ethical decisions too. Should a self-driving car be allowed to slam into pedestrians to save its passengers from a head-on collision? Should a negotiation app be able to detect stress in your opponent’s voice? And who makes these decisions: the user, the system’s…

Europe's latest quantum computer is set to arrive in the Netherlands. The Dutch IT cooperative, SURF, which supports education and research institutions, has secured funding from the European EuroHPC programme to make this possible. Researchers from Leiden University will play a key role in the project,…

Researchers found a way to run programmes that should be impossible to carry out on an imperfect quantum computer. Such programmes are very computationally demanding and the quantum computers that currently exist are not yet up to that task. Unless you use a clever trick, Simon Marshall and Vedran Dunjko…

Joost Batenburg is a mathematician and computer scientist who works to build bridges to other disciplines. He hopes to bring intelligent software to fields where it can make a difference. Conversely, he also seeks connections to the disciplines that are needed to make AI a success.

In the future, physicians may be able to identify dementia much earlier than they can today because a computer algorithm will be able to predict from brain scans how our memory is going to develop.

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

The lecture series “Humanity in the Automated State” continued on February 12, 2026, at Leiden Law School with Professor Madalina Busuioc of VU Amsterdam, a public governance scholar, AI-DG Lab co-director, MSc programme founder, and recipient of a European Research Council grant.

A major grant for research into machine learning algorithms for quantum computers. With this ERC Consolidator grant, Vedran Dunjko and his colleagues hope to discover which real-world problems a quantum computer can solve faster than a normal one.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

The imaging group focuses on bio-imaging, image analysis and visualization.
