This is an Erasmus+ International Credit Mobility project of the Faculty of Science with three universities in Colombia.

Imagine how much time, money and discomfort it would save: a personalised treatment for each individual patient. Precision medicine like this is coming ever closer, thanks in part to Elise Dusseldorp’s algorithms. They retrieve a wealth of information from research data.

At Leiden University, researchers from all disciplines work together to find answers and design innovations in the field of artificial intelligence.

Does powerlessness and dependence lead to the legitimation of the social, political, and economic status quo and of those in authority?

Leiden alumni find work in all kinds of interesting places. We gather the stories of our alumni and publish then regularly in our alumni newsletter and in Leidraad magazine. You can find all their stories on this page. They give a good impression of what life is like for Leiden alumni after they have…

Online platforms such as YouTube, Facebook, and X (formerly Twitter) have become part and parcel of everyday media use. Journalists incorporate posts from politicians into newspaper reports, scientists share their insights in short posts or videos, and the judiciary uses social media to explain their…

Some children and adolescents find it hard to attend school because of anxiety and/or depression, a problem which is often referred to as school refusal. The main research question is how we can best help these young people reduce their emotional distress and increase their school attendance in order…

Baroque flautist Jed Wentz followed two years of dancing classes in order to develop the right feeling for the gestures required for the Baroque French opera genre ‘tragédie en musique’. In his dissertation, the links between gesture affect and rhythmic freedom in the performance of the tragédie en…

This project looks at the current practices of marriage law in Indonesia. It examines the often ambiguous views different groups hold of marriage, from local villagers in Bengkulu to women’s activists in Jakarta, and how these relate to the development of national law on the one hand and local practices…
