Our Vision

Our research programme is designed to contribute to greater social security, and a safer society for all. The Social Resilience and Security programme aims to generate interdisciplinary insights in the field of security and interventions, by bringing together researchers from five different faculties: Social Sciences, Governance and Global Affairs, Law, Archaeology and Humanities. In short, we aim to generate an exciting and productive research agenda, with valuable practical applications in the domain of safety and security. Further, we aim to build a durable and long-lasting collaboration between the five Social Sciences and Humanities (SSH) faculties at Leiden University. Our hope is that this trans-disciplinary approach will also benefit and inspire our students, encouraging them to synthesize different viewpoints and to think more broadly about the topics of their interest.

On this website you will find information about the interdisciplinary programme, the research projects we are developing, our team and our contact details. Please also see our webpage at Leiden University and our twitter!


Marieke and Jolien discuss homicide trends in the Netherlands in their recent contribution to the blog of the Institute of Security and Global Affairs.

How can we support young people in building resilience? Maxi and Anne-Laura give some insight in their recent blog.

Take a look at this article in the New York Times that discusses an article by Maikel and a colleague, studying the emergence of money systems in ancient societies. If you prefer to read the academic publication, you can do so here.

Join Anne-Laura to learn more about Resilience in this podcast produced by the Association of Child and Adolescent Mental Health.

About the programme

As our society becomes increasingly complex, it is critical that we better understand how we can deal with fundamental issues such as societal and personal security, and resilience against threats to our security. Over the past two decades, knowledge about transgressive behaviours threatening our security have greatly increased, with direct applications in education, law, conflict, and cooperation. At the same time, transgressive behaviours have been studied in relative isolation, from separate disciplinary angles. Transgressive behaviours affect individuals and institutions across the world, regardless of demographic, ethnic, or socio-economic background. As such, there is a need to study these behaviours, and resilience against such behaviours, using multidisciplinary, or even interdisciplinary approaches. In the Social Resilience and Security programme, we seek to provide a broad and deep understanding of the dimensions and aetiology of transgressive behaviours, the effects of interventions, and resilience against such behaviours. This could include determinants of, for example, violent behaviour and resulting prevention initiatives. But it also concerns the effects of social (individual) interventions, the aims and objectives of legal interventions and the effects of policy interventions.  

Please take a look below for our ongoing and affiliated projects.


The Social Resilience and Security programme is brand new! The conceptual development of the programme is progressing by two different methods, which are outlined briefly below. To get a flavour of related research projects from our group, please see the section Affiliated Projects.


To generate the research questions that will guide our programme, we are using the Delphi-method. The Delphi-method is designed specifically to extract and collate insight from a panel of experts and make optimal use of the variety of expertise represented (Elmer et al., 2009).


The second initiative designed to contribute to the conceptual development of the programme is a 5-day seminar on the topic of Online Transgressive Behaviour. We hope that the workshop can take place in the summer of 2021. If it goes ahead, you will of course read about it in the News section.

About us

Project Leaders

Anne-Laura van Harmelen

Faculty: Social and Behavioural Sciences

My research aims to understand how we can increase resilience in young people with a history of adverse early experiences. My work helps to inform prevention and intervention strategies aimed at reducing mental health and behavioural problems in at-risk young people. By understanding and improving social resilience, my research aims to increase social safety.

Marieke Liem

Faculty: Governance and Global Affairs

My research focuses on interpersonal violence. I study this type of transgressive behaviour from a background in forensic psychology and criminology. I believe the interdisciplinary programme gives us a unique opportunity to structurally bring together interdisciplinary insights to answer questions regarding violence and interventions.

Anna van Duijvenvoorde

Faculty: Social and Behavioural sciences

I am trained in both cognitive neuroscience and developmental psychology. In my work I study how brain development relates to adolescent’s decision-making and learning. My motto is that science is better together.

Arnaldo Rabolini

Faculty: Governance & Global Affairs

Arnaldo started his PhD within the programme in September 2021, under the supervision of Marieke, Anne-Laura and Jolien.

David Fontijn

Faculty: Archaeology

I study the social evolution of society in periods long before people were writing down their own histories. It is my conviction that archaeology has an unrivalled potential to inform us on the constitution of society by allowing us to reconstruct histories lasting thousands of years. In particular, I see one of its unique strengths to inform us on how things have shaped society and vice versa.

Ellen de Bruijn

Faculty: Social and Behavioural sciences

I study the cognitive and neural mechanisms of action-control processes that are necessary to interact successfully with the environment and with other humans. I investigate modulations of these processes in healthy volunteers and in clinical populations from a social neurocognitive perspective. I make use of various approaches and methods, such as behavioural experiments, EEG, and fMRI techniques, as well as psychopharmacological manipulations.

Henk van Steenbergen

Faculty: Social and Behavioural Sciences

In my Affect, Motivation & Action lab, we use a multi-method approach to investigate the fascinating relationship between emotion and cognition in humans. My most recent work investigates the role of the endogenous opioid system beyond pain relief. In particular, I study how our body’s own opioids modulate cognition, and how they mediate positive experiences and resilience.

Jan Sleutels

Faculty: Humanities

In my research I concentrate on problems of mental content in contemporary philosophy of mind and in epistemology. Which factors are responsible for determining the contents of our thoughts, perceptions, desires, and other mental states? It may be argued that the human mind is subject to substantial change: the model of mind that applies to earlier stages of technological development may be substantially different from current models of mind.
