Squatters and autonomous movements have been in the forefront of radical politics in Europe for nearly a half-century—from struggles against urban renewal and gentrification, to large-scale peace and environmental campaigns, to spearheading the antiausterity protests sweeping the continent.

Erasmus+ Cooperation Partnerships (Key Action 2) are transnational projects designed to develop and share innovative practices and promote cooperation, peer learning, and exchanges of experiences in the fields of education, training, and youth. There are two kinds of Cooperation Partnerships; those…

In this article, Yannick Veilleux-Lepage and Tommy van Steen, assistant professors at the Institute of Security and Global Affairs, discuss the degree of consensus within the field of terrorism studies regarding the impact of the COVID-19 pandemic on the activities of violent non-state actors.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

The Old Observatory houses four historical telescopes. On this page you can learn more about them.

SciSTIP was established on 1 April 2014 as part of the DSI-NRF Centres of Excellence Programme funded by the South Africa’s National Research Foundation (https://www.nrf.ac.za/). SciSTIP is hosted by the Centre for Research on Evaluation, Science and Technology (CREST) at Stellenbosch University and…

These syntheses allow the team to determine the extent to which schools-based interventions are effective at targeting radicalisation-related outcomes.

Cyber-attacks, privacy-related problems or failures in functioning: many technologies that are used every day have security issues that are solved when the software is already in use. An interdisciplinary project, in which Olga Gadyatskaya, Harry Wijshoff, Alex Uta and Kristian Rietveld from the Leiden…

In 2021, the National Cyber Security Centre (NCSC) asked Leiden University to conduct a rapid review of best practices and possibilities for follow-up research on the integration of behavioral sciences in security by design methodologies and projects. This academic field is called security by behavioral…

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

This September a new Masters Track

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

Below you can find information about the research projects on public leadership of the public management research group at the Institute of Public Administration.

NASA’s telescope SOFIA has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. Leiden PhD candidate Andrew Barr writes about it in the Astrophysical Journal. The scientists found massive quantities of water and organic…

This book explores the intellectual history of the Dutch empire from the sixteenth century to the postcolonial era, going beyond systemic thinkers to understand how empire was perceived in day-to-day life. It takes a transnational and transimperial approach to the Dutch empire, connecting European,…

In 2019, LUGO started a petition demanding an ambitious sustainability vision for 2030. This petition was formulated based on what LUGO deemed achievable rather than based on the restrictions of the present. We believe that sustainability should be one of the core values of the next central policy…

The Faculty of Humanities’ accommodation needs to be modernised. The education and research buildings are seriously outdated and non-sustainable, which could ultimately compromise the quality of our education..

How do humanitarian organisations adapt cyber incidents to their specific priorities and needs, and how can they adapt strategies of other organisations?

Speeches and speech acts have been crucial in settling the question at the centre of every political debate: who gets what, when and where?

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Every year The Young Academy (a sub-group of KNAW) nominates ten talented researchers to join their ranks. This year two of the nominees are from Leiden University: Quentin Bourgeois and Frans Snik.

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

The goal of the LIACS Media Lab (LML) at Leiden University is to conduct state-of-the-art research in the areas of deep learning, artificial intelligence and computer vision.

Leiden University is aware of its role in society and wants to create a green, healthy and inclusive campus and have a positive impact on the field of climate and circularity.

Together Leiden University, Delft University of Technology and Erasmus University Rotterdam form the strategic alliance Leiden-Delft-Erasmus Universities.

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

The League Against Imperialism: Lives and Afterlives explores the dramatic and engaging story of a global institution that brought together activists across geographical and political borders for the goal of eradicating colonial rule worldwide.

This subproject offers a political and transnational perspective on the development and uses of public memories of the Revolt in the seventeenth century.
