Increased public trust in law, government and democracy.

Polarisation is pervasive: in the workplace, within teams, and even at the top of organisations. Discussions become entrenched, emotions rise, and collaboration falters. Connections are lost through ‘us versus them’ thinking. The question is how leaders can maintain space for dialogue when tensions…

What are the main issues leading to polarisation and division? What is the role of social exclusion in these processes? How can we inform and design better policies to safeguard young people from falling prey to intolerance and polarisation? The DRIVE project, led by Leiden University in The Hague,…

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

A new way to decipher the light from distant worlds could give us unmistakable evidence of extraterrestrial photosynthesis, and maybe alien plants, finds astronomy author Colin Stuart in the New Scientist. In his article, he describes the work of the group led by Leiden astronomer Rob van Holstein.…

An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

Leiden University is an international, broad-based university. We distinguish five core domains for our research and teaching activities.

Tessa van Schagen and Naomi Sedney know exactly how to combine their Psychology study with top-level sport. Both students are running in the 4 x 100 metre relay at the Olympic Games. Van Schagen: 'Fellow students think it's great that I'm going to Rio.'

With this grant the researchers seek to shed light on the factors which play a role in transmitting jihadist ideas, and explore possible ways to mitigate this transmission.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Water is all around us and is vital for all aspects of life. Studying the various compounds and life forms that inhabit natural waters lets us better understand the world around us.

We are pleased to invite abstracts for a conference on ‘Advancing Social, Economic, and Cultural Rights in a Polarised, Digitalised, and Unequal World’ to be held at Leiden University on 4 and 5 September 2025, in collaboration with Netherlands Network for Human Rights Researh (NNHRR).

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

In a time of growing polarisation and declining trust, the rule of law is under pressure. The system as we know it today only took shape 177 years ago, with the constitutional reform of 1848. Carla Hoetink emphasises: ‘The democratic rule of law was originally designed to prevent violence and revolu…

Tahir Abbas, Associate Professor in Terrorism and Political Violence at ISGA, explained how polarisation and social exclusion were at the root of radicalisation around the world. Papers ‘The News’ and ‘Dawn’ wrote articles about it.

What Determines Perceptions of Bias toward the International Criminal Court? Evidence from Kenya. In this article, published on the website SAGE Journals in the Journal of Conflict Resolution, the authors Geoff Dancy, Yvonne Marie Dutton, Tessa Alleblas, Eamon Aloyo examine the attitude towards international…

In this study, Tessa Dool and Thijs Bosker estimate the microplastic uptake of two odontocetes in the Mediterranean Sea and the Norteast Atlantic.

The Faculty of Social and Behavioural Sciences (FSW) aims to play a leading role in gaining insights on current developments in society.

Researchers from the Institute of Public Administration and the Institute of Security and Global Affairs at FGGA are launching a new research programme: Governing Polarized Societies (GPS). The programme will focus on the way in which governments are dealing with the increasing polarisation in society.…

Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

Following the mid-term review, one of the faculty's ambitions is improving diversity and inclusion in our education.

Indigenous Pasts and the Roman Present

The rise of extremism in Europe has increased polarisation. The EU-funded DRIVE project, led by Tahir Abbas, Professor of Radicalisation Studies from Leiden University’s Institute of Security and Global Affairs, explores how social, structural, and individual factors contribute to radicalisation, offering…

The Politics and Governance department of the Institute of Public Administration focuses on the complex interaction between politics and governance. Our research explores contemporary issues such as the impact of global crises, populism, and polarisation at various levels of government.
