The modern-day Caribbean is a stunningly diverse but also intricately interconnected geo-cultural region, resulting partly from the islands’ shared colonial histories and an increasingly globalizing economy.

The main goal of this thesis is to achieve advanced control of binding properties in bis-pyrrolic and macrocyclic pyrrolic receptors by light.

Leiden University computer scientists Yu Liu, Yanming Guo and Michael Lew are a step closer to their ultimate goal: search engines with visual recognition. Their publication of a new algorithm for fusing multi-scale deep learning representations has been received with great enthusiasm. No other algorithm…

This study investigates the perception and production of emotional prosody by native and non-native listeners and speakers, i.e. Chinese and Dutch listeners and speakers, including Dutch L2 learners of Chinese.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

Combining insights from regulation theory, law and computer science, this book explores policy and digital enforcement solutions that could strengthen EU consumer protection against dark patterns – a policy priority in recent years and the near future. The book illustrates why more technology-specific…

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

A new publication that brings together perspectives on language contact phenomena across temporal and spatial dimensions.

The Leiden Centre of Data Science and the Leiden Institute of Advanced Computer Science are part of a consortium that will carry out research on making illustrated and handwritten archives digitally accessible. The project is funded by NWO.

Despite a lack of specific legislation on this issue, Dutch Minister of Justice and Security Dilan Yeşilgöz is allowing the national police force to experiment with facial recognition technology.

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…

With the conference circuit slowly reopening after Covid forced almost all academic interactions online, thousands of conference attendees descended on Brussels for Europe’s largest technology conference. eLaw’s annual sponsorship of one of the many CPDP conference panels brought a diverse range of…

Misleading social media posts are falsely claiming that the Dutch supermarket chain Jumbo uses facial recognition at self-service checkouts. Jumbo denies this, although it has launched trials with AI cameras to combat shoplifting without using facial recognition.

New publication by Christa Tobler and co-author Joel Günthardt on the mutual recognition of professional qualifications

A better balance between teaching and research duties, greater recognition of team performances and the elimination of simplistic assessment criteria. The ‘Academia in Motion’ paper published by the Leiden University Recognition and Rewards describes the main problems with recognition and rewards in…

Recent developments in AI mean nobody is anonymous nowadays. The search engine PimEyes can find any photo of anyone that’s ever been placed online. No more Tinder Swindlers… or personal privacy. Everyone’s findable now. But is that even allowed?

Marianne Maeckelbergh, an anthropologist affiliated with Leiden University’s Institute of Cultural Anthropology and Developent Sociolog, has been awarded a WCC ‘Special Recognition Award’. This awards brings Marianne Maeckelberg official recognition as ‘young outstanding researcher’.

The Data Science Research Programme at Leiden University combines data science with PhD projects in a wide range of disciplines. The programme has been running for over two years, and is producing the first astonishing results. A number of PhD candidates talk about their experiences and research bel…

OSCNL, the international network of Open Science Communities, receives recognition

Tropical butterflies adapt to their environment to improve their chances of survival. The changes are triggered by hormone signals that transmit information about temperature to the butterflies' tissues. Biologist Ana Rita Mateus shows how a complex combination of environment, physiology and genetics…

Vaccines are an extraordinary category of biopharmaceuticals. They are usually prophylactic and come in many types, from whole bacteria to peptides and nucleic acids. They are very cost effective and almost every human on the planet is vaccinated. The latter mandates that vaccines have to be extremely…

Using artificial intelligence is more complicated for the government than for companies. Bram Klievink, Professor of Public Administration, aims to identify the problems and find solutions.

Thanks to deep learning, computer program AlphaZero plays better chess than the best person. The computer wins because it can predict further ahead than a human being through pattern recognition. Aske Plaat discusses this special development in Dutch newspaper NRC. He expects the major tech companies…

Leiden University and VU Amsterdam are developing a joint research project for a digital platform on which you can compose and share storylines with the use of images. Such interactivity will make a boring high school history lesson much more exciting and personalized. Furthermore, it will stimulate…
