In this thesis, we investigate how deep generative models (AI models that can create new designs) can be better utilized for technical and industrial design. Our goal is to generate designs that are not only realistic (plausible), but also efficient, reliable, and usable in complex 2D and 3D applica…

This lecture will be hosted on Thursday, 21 May 2026 at 6:00 pm - 7:00 pm.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

This collection, edited by Sophie Vériter, Monica Kaminska, Dennis Broeders and Joachim Koops, includes six papers exploring and investigating European responses to COVID-related disinformation, specifically the responses of France, Sweden, Germany, the United Kingdom, Serbia, and Hungary.

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

Multinationals use loopholes in the tax treaties between different states. A possible solution would be to eliminate all these loopholes in one go by creating a central global treaty. Leiden researchers are investigating whether this kind of mega-treaty is feasible.

How do digital technologies affect adolescent mental health and resilience? How do we foster a secure online environment? How should we deal with increasing rates of online crimes among adolescents? During the mini-symposium ‘The effect of the online world on adolescents’, presented by the interdisciplinary…

In the late colonial Netherlands Indies, starting from 1892, homes were set up for the re-education of children. At first by private individuals, later by the government. Much later still, privately funded institutions existed alongside government-funded ones. Annelieke Dirks’ defence on 23 June 201…

Although he works for the Deloitte international management consulting firm, Robin Bergman identifies himself as an "artist, designer and researcher". He is fascinated by technology and nature, and the tensions that exist between them.

Knowledge and culture subproject 4:

To truly understand complex regions such as the Middle East and Asia, you have to know their culture, history and local societies inside out. Driven by curiosity for other cultures, the Leiden University Institute for Area Studies (LIAS) provides an understanding and analysis of current and historical…

Democratic citizenship refers to the capacity and willingness of citizens to actively influence the functioning of state institutions. While considered a vital correlate of democratization and the rule of law, its largely western-oriented literature rarely studies the forms of democratic citizenship…

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?
