The perfect ship is light and sleek for speed, but also needs to be strong and stable for safe sailing. These and other conflicting requirements make it difficult, even with a supercomputer, to find the ideal design. Computer scientist Roy de Winter has developed an algorithm that helps strike the perfect…

In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…

Ships are still emitting too much nitrogen oxide. Till now it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. Kurchaba received her PhD on 11 June.

They never cross our minds until, that is, they become damaged and then they’re a huge problem: our sewers. Their maintenance could be much faster and more accurate, PhD candidate Dirk Meijer has discovered. Algorithms are also proving to be a godsend deep underground.

In January 2021, eLaw joined the Computers Privacy and Data Protection (CPDP) Conference that is about privacy and data protection. The group on Law and Digital Technologies at Leiden University put together a panel that combined perspectives on Art, Society, & Technology.

Carlotta Rigotti, post-doc researcher at eLaw - Center for Law and Digital Technologies, and Alexandre Puttick (Bern University of Applied Science) presented some research outputs of the Horizon Europe BIAS project during the European Workshop on Algorithmic Fairness '23.

On September 15th a new series of lectures will start, the Joint Lectures on Evolutionary Algorithms (JoLEA). This series of events is aimed at disseminating the latest, top-quality research on EAs. The lectures will feature world-renowned speakers, local researchers, and PhD students.

Algorithms solve problems. But which algorithm is best suited to which problem? During his doctoral research, Diederick Vermetten developed methods to figure this out. And that is important for the entire field.

Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

An X-ray scanner, some small metal balls, and a newly developed algorithm. That is all you need to make a 3D model that enables you to look inside art objects without dismantling them. Thanks to the research of Francien Bossema (Centrum Wiskunde & Informatica and Leiden Institute of Advanced Computer…

The Leiden Ranking – Open Edition is completely transparent. The ranking compiled by the CWTS uses open data and publishes the algorithms that are used.

From predicting Alzheimer’s to the growth of organisms: psychologist Marjolein Fokkema’s algorithms can be used in many disciplines. They also provide inspiration for her songs, theatre shows and life lessons. What drives this rocking researcher?

Carlotta Rigotti and Dr Eduard Fosch-Villaronga from Leiden University presented the Horizon Europe BIAS project and its preliminary findings on fairness and diversity biases of AI applications in the labour market during the 'Algorithms for Her?' conference.

How do we deal with large sources of greenhouse gases? Do schools provide a socially-inclusive environment for all children? And how can we protect Earth’s nature? These questions have two things in common: they are complex global challenges, and data can help answer them. Mitra Baratchi is computer…

At the end of October the students of MA International Relations: European Union Studies once again made the journey to Brussels for three days of behind-the-scenes insights into EU politics and policy-making. From the intricacies of European defence cooperation to the future of digital trade, students…

Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics — or if it just looks like it does? In a groundbreaking study, physicists from Leiden, Beijing en Hangzhou found the answer to this question.

In november 2023 is Anne Fleur van Veenstra, wetenschappelijk directeur van TNO Vector, benoemd tot bijzonder hoogleraar ‘Governance van data en algoritmen voor stedelijk beleid’.

Lecture, Tuesday Talk

Predicting the collective behaviour of systems, like a large group of people electing one of the parties, is no easy task. But there’s a theory that scientists have been using for decades to do just that: the theory of Gibbs measures. Last week, mathematician Mirmukhsin Makhmudov earned his PhD for…

In healthcare, gender and sex considerations are crucial because they affect individuals' health and disease differences. Yet, most algorithms deployed in the healthcare context lack close consideration of these aspects and do not account for bias detection. In their latest paper, Eduard Fosch-Villaronga,…

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

What began as a PhD project has grown into a website with 120,000 unique visitors each year. With the platform OpenML, researcher Jan van Rijn is contributing to open science, aiming to make machine learning more transparent, accessible, and fair.

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,…

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,…

How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.
