There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Welcome to the Hensen Lab! We are a young dynamic experimental research group starting at the Leiden Institute of Physics. Our lab addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity.

Adults are more likely to reoffend after a short prison sentence than comparable adults with a non-custodial sentence, Leiden University research shows. This is true for the likelihood and extent of repeat crime.

As a result of production pressure, judicial powers focus more on efficiency and less on making sure they get to the truth. Professor of Criminology Jan de Keijser believes that establishing the truth in court cases is under threat. Inaugural lecture 7 November.

What is the nature and scope of violence? Who offends, and in what context? Who are the victims? And how can we design suitable intervention and prevention strategies? In this track, you will be familiarised with the many faces of violent offending, to provide the knowledge and tools to understand,…

Leiden Law School offers intensive education programmes that provide tremendous opportunities for talented students.

PhD defence

Recent welfare reforms in the Netherlands show a trend of reducing welfare accessibility and increasing obligations. Although the effects thereof on directly-targeted economic outcomes, such as welfare dependency and labor participation, are often assessed, potential spillovers to other economic and…

Human trafficking is much more than kidnapping and selling people. Those who commit labour exploitation can, for example, also be sentenced for human trafficking. Criminologist Masja van Meeteren hopes to simplify the complexity of the phenomenon by charting the different forms of labour exploitati…

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

In 2022, many of our staff and students won fantastic prizes and were awarded important research grants.
