The central aim is to systematically study differences in crime patterns and social control between migrants and non-migrants in early modern Frankfurt am Main.

The research that is united in the Liveable Planet programme, touches upon a wide range of aspects of human life. The goal is to deepen and expand the scope and to connect more researchers. The following case studies are examples of current research projects.

We explore the particle physics and quantum world at the time of the big bang.

Bone research provides plenty of detailed data about the health of a person or a group. This data is not only used to reconstruct the past but also to fight disease today.

Spontaneously helping one another, why do we bother? It is believed that lending a hand to others promotes social bonding, helping us to connect with each other and even build friendships. In our experiment, in which the adult researcher ‘accidentally’ dropped matches on the floor, most adolescents…

Why did fewer women suffer from osteoporosis in the past than today? And which aspects of a city make public spaces safe, accessible and comfortable for all residents? These two research questions will be explored in more detail thanks to an Impulse Grant from the Leiden University Fund.

Combining different disciplines, researchers work together to formulate innovative solutions to societal problems.

We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

Our mission is to improve the description, prediction, understanding and the prevention and treatment of mood disorders, including unipolar and bipolar depression, as well as suicidal thoughts, feelings, and behaviors. To tackle this ambitious mission, we focus on several research streams.

There are around 300,000 people in the Netherlands who donate blood on a regular basis. Women can give blood up to three times a year and men up to five times, resulting in approximately one million blood donations each year. Patients that receive this donated blood are already in a vulnerable condition,…

Many Asian countries are in a process of democratisation. The expectation was that citizens would gradually gain more control over the functioning of their elites. Experts from Leiden have concluded that this process often fails to improve the quality of the administration. They researched the nature…

Pandemics, terrorist attacks, environmental disasters... These are real threats, which we cannot ignore. In fact: we need to prepare better for the large-scale crises of the future. Preferably in a way that suits our lifestyle and respects our social values. Over the next ten years, an interdisciplinary…

‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

The 2017 Nobel Prize in Physics has been awarded to Rainer Weiss, Barry Barish and Kip Thorne for their work on the measurement of gravitational waves. Thorne was Lorentz Professor in 2009 in Leiden. Physicist Jan Willem van Holten explains why this is such an important discovery. ‘A new branch of astrophysics…

The first larger quantum computers will soon be available. These computers need new software. Researchers at Leiden University have been awarded a Gravitation grant to develop the necessary software. They will be collaborating with colleagues from other research institutions.

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…

What is the role of technology and cyberculture in Korean social structures and in the potential formation of a new collective subjectivity? How do we reorient disoriented souls?

How does stress affect different components of behavioral impulsivity and aggression in patients with Borderline Personality Disorder compared to clinical controls (patients with Attention Deficit Hyperactivity Disorder) and healthy controls?

This book presents an introductory survey of the major themes, thinkers and texts, philosophical genres and profound insights of the Chinese philosophical tradition. Its coverage ranges from the foundational history of Chinese thought in the 6th–5th centuries BCE up to the present day.

What is the first thing you think of when you hear the word UN? Is it just the Security Council and the ‘blue helmets’ or is there more to it? These are some of the questions tackled by the Chair’s research group.

Cells in our bodies are often threatened by errors in our own proteins. The FLOW consortium, comprising scientists from various institutions including Leiden, is poised to meticulously map out for the first time how cells control proteins, correcting or removing faulty ones. This endeavour holds promise…

The Gravitation programme NETWORKS has been awarded a COFUND grant of 3 million euros. Half of this comes from the European Commission's Marie Skłodowska-Curie Actions programme, with industry partners paying the other half. Of the fourteen new PhD candidates, two will join Frank den Hollander's research…
