In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

Human measures to protect lions have an impact on the genetic health of populations. Leiden and Kenyan scientists discovered this by analysing the DNA of 171 Kenyan lions. ‘By fencing reserves, for example, the chance of inbreeding increases.’ With the knowledge and tools from the research, management…

The aim of this study is to identify the side effects during treatment with methylphenidate and to investigate how children experience the use of the medication (such as Ritalin, Concerta and Medikinet).

Some examples of AI-research done at Leiden.

People who have negative expectations about a treatment actually experience more pain. Merve Karacaoglu discovered in her PhD research that anxious and pessimistic individuals are particularly susceptible to this nocebo effect. However, this sensitivity comes with a silver lining.

Patients on patient forums share all sorts of things about their illness: from side effects and advice to messages of support. PhD candidate Anne Dirkson uses artificial intelligence (AI) to retrieve this information. ‘Ninety per cent of the side effects weren’t officially registered.’

Researchers of the Leiden University Medical Centre (LUMC) and the Leiden Institute of Chemistry have made an important discovery about the commonly used anti-cancer drug doxorubicin. They have found a way to reduce its side effects without sacrificing the effectiveness of the medication. This is encouraging…

The Life in Custody (LIC) Study comprises a large-scale research project into prison climate and the quality of prison life in Dutch prisons.

The Dutch Government recently announced measures to limit the loss of purchasing power. These include, for example, raising the minimum wage and healthcare benefits. Another way for households to maintain purchasing power is to work more. Olaf van Vliet, Professor of Economics, explains the effects…

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

We are confronted on a daily basis with news about the Corona virus and its consequences. We read alarming headlines like 'Dutch becoming increasingly anxious about Corona virus' or 'Huge fears and stress about Corona crisis'.

In the online panel discussion of ESOF 2022 ‘The effect of the online world on adolescents’, together with Amy Orben, Professor Eveline Crone, Sterre van Riel, Professor Anne-Laura van Harmelen and Professor Jan Sleutels, Professor Ton Liefaard shared his research on adolescents and the online world…
