The Research Group 'Violence and Violence Prevention' studies interpersonal violence. We seek to better understand the dynamics underlying interpersonal conflict.

Research on lethal violence related to criminal activities.

Drug-related homicide (DRH) has the potential to act as a valuable indicator of wider drug-related crime. Yet DRH remains a knowledge gap within this broader field of study.

Citizens in multiple crime-ridden countries strongly support the militarization of security—that is, placing the military in charge of traditional policing duties. Yet, we know little about the determinants of such support. Do people approve of militarization even in the face of human fatalities? Political…

Project TARGET aims to improve our understanding of gun violence in Europe and the relationship between gun violence and firearms trafficking.

Firearms and violence in Europe–A systematic review by Katharina Krüsselmann, Pauline Aarten, Marieke Liem

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,…

How many men and women die per year at the hands of others? What are the motives behind these killings? Are there as many homicides today as years ago? How can we explain the rise and fall of homicides over time? And: What is the influence of (early) childhood and adolescence on the likelihood to commit…

Under what circumstances do paramilitary groups limit their use of political violence? This article examines the use of political violence by the PIRA.

The aim of this project is to study what makes an act or form of violence a specifically political reality.

In this minor programme, students will become familiar with the nature and scope of violence; the ways in which it impacts public order, and the ways in which society can respond to and, ultimately, prevent violence.

Understanding the evolving landscape of extremism in the 21st century.

In the Drug Research theme, we primarily work with rodents. Rodents, such as mice, are one of the most common laboratory animals. These small mammals are easily housed and exhibit a rapid rate of reproduction.

In this project, we seek to assess, map and understand the risk factors associated with fatal domestic violence.

Can drugs that target host signaling pathways be used to eradicate antibiotic-resistant bacteria?

Can conspiracy constructions explain for hatred of the system? And if so, should conspiracy constructions be considered to be a risk in terms of national security?

Representations of violence are often said to generate cathartic effects, but what does “catharsis” mean? And what theory of the unconscious made this concept so popular that it reaches from classical antiquity to the digital age?

Is is possible to better predict the validity of drug candidates?

To assess the impact of illicit firearms trafficking on gun violence, this research looks at the scope, characteristics and contexts of firearm violence, and also the scope and nature of firearms trafficking in Europe since the new millennium. Nils Duquet, Dennis Vanden Auweele and Marieke Liem created…

The judge as a problem-solver in domestic violence cases involving child victims.

How are new drugs developed? This question is central to the Minor Modern Drug Discovery (MDD), which covers the entire trajectory from disease to drug molecule and vice versa. The various research groups involved offer a complementary and interdisciplinary perspective by connecting the diverse subjects…

Do you have to be able to say everything on Twitter and Facebook? Is Instagram morally obliged to remove photos from attacks? Should we allow the terrorist group to recruit new members on the internet?

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

The drug discovery pipeline is used to describe the stages in drug discovery. The earliest stage concerns with the identification of potential targets and molecules ('hits') that can modulate their function, while more advanced stages are about developing these hits into viable experimental drugs and…

The Data-Driven Drug Discovery Network (D4N) is an initiative by researchers from Leiden University and collaborators to join efforts in applying and developing novel techniques from data science to drug discovery and related topics from bioinformatics.

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

Our research in the area of safety sciences aims to increase the mechanistic understanding of cellular toxicity of drugs and, in a broader sense, chemicals.

Drug-target binding kinetics determine the time course of the central event in pharmacotherapy: Drug-target interaction.

Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

In this research group, headed by Prof. Erik Danen, the aim is to unravel cellular signaling mechanisms in normal and diseased cells, with a long-standing interest in cell adhesion signaling. In complex multicellular organisms such as ourselves, a division of labor emerges where different tissues and…

This interdisciplinary study focuses on (trans)national ethnic and popular networks, combining historical-ethnographic and computational methods to understand the ‘workings’ of networked conflict interfering in the increasingly violent conflict in the Sahel (Africa) and beyond. The project focuses on…

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

Improving healthcare with our scientific discoveries: that is the goal of pharmaceutical research at Leiden University. And there’s a lot involved in that. Our research starts with the discovery of the effect achieved by a particular substance, and sometimes continues all the way through to the development…

This study focuses on violence involving juveniles in conflict with the law who are deprived of their liberty in different institutions within the framework of the (juvenile) criminal justice system (inter alia, police detention, pre-trial detention and deprivation of liberty after conviction or sen…

The master's specialisation Drug Discovery and Safety at Leiden University provides students with research-oriented education into the discovery of new drug targets and new lead molecules, particularly in the field of cancer, through a combination of advanced imaging techniques (‘systems microscopy’),…

This article describes the phenomenon of firearms violence and the importance of including non-lethal firearms violence in understanding this phenomenon.

The illegal use of hand grenades has generated a lot of public interest over the last few years but very little is known about the nature and extent of these incidents. This research project is trying to fill that gap.

Mechanisms fro drug resistance

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

Both play and politics have the potential to create worlds in which new rules apply, meanings are created, and possibilities emerge for collaboration, strategy and creative solutions. In this sense, play and politics have always been very much alike. But what happens to this kinship in a post-digital…
