Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

Is blended care a feasible and effective treatment method for social anxiety in adolescence?

Technological advances, such as virtual reality, augmented reality and online assessment platforms are rapidly improving. These tools could potentially contribute to neuropsychological assessment that is more efficient and of higher quality.

To reach a larger audience beyond the academy, a number of activities in the cultural realm have been programmed over the years.

The authors systematically search and review relevant definitions of Security by Design (SbD) in comparison with Privacy by Design (PbD).

Does an Emotional Working Memory Training show a beneficial transfer effect on emotion regulation (reappraisal) capacities in patients with Borderline Personality Disorder?

Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…

Sound & Score brings together music expertise from prominent international researchers and performers exploring the intimate relations between sound, score and notation, and the artistic possibilities that this relationship yields for performers, composers and listeners.

This project analyzes to what extent hodegetical textbooks relied on each other in warning their readers against vicious habits, how much continuity their catalogs of vice displayed, and to what extent vices that persisted throughout the 18th and 19th centuries were associated with easy-to-remember…

When and how does social anxiety develop? How can it go astray in some adolescents? How can we help troubled young people to attend school regularly and return to a normal developmental pathway?

Van Vark defended her dissertation 'Separation and immersion: the changing role of the armed forces in Northwestern liberal democracies’ on 17 October 2025. The doctoral research was supervised by Maartje van der Woude and Erwin Muller.

Restructuring and insolvency laws play a pivotal role in addressing the often conflicting interests of stakeholders of financially distressed companies. Whereas financial distress is an inherent risk of entrepreneurship in market-based economies, legal tools serve an important role to ensure an orderly…

Crises like climate change and loss of biodiversity threaten our planet. That’s why sustainability is an important topic in research and education across Leiden University. On this website you read how scientists from many disciplines work together in researching sustainability.

The 2022 Academy is co-organised by Leiden, Delft Erasmus Universities (The LDE Alliance) from the Netherlands and the National Research and Innovation Agency (BRIN). Aim of this five day programme is co-creation in the field of teaching and research on sustainable urbanisation. It also aims to facilitate…

79 students, 15 organisations, and 16 projects: within the master’s programme Governance of Sustainability, diverse groups of students worked together with organisations to tackle sustainability challenges. In this blog, Annemiek de Looze reflects on how the power of their transdisciplinary approaches…

Help us spot and clean up the plastic in the canals of Leiden! Leiden University is calling on the good folk of Leiden to help our researchers study the plastic in the city’s canals. And if you’d like our canals to be plastic-free, why not donate towards a fleet of canoes to clean them up?

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

We would like to present to you a simple guidebook about living a sustainable life as a student in the cities of Leiden and The Hague. Whether you are a first-year student still trying to find your way around or already doing your masters – students wanting to explore more sustainable options and save…

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

Many metalloenzymes that are key to bioenergetics are membrane enzymes, with canonical examples the complexes I, II, III and IV in the mitochondrial inner membrane. To study these enzymes in a native-like lipid membrane environment, we aim to develop novel bioelectrochemical techniques.

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

An Institute of Environmental Sciences, ambitious goals for energy, water and CO2 emissions. Leiden University plans to take the lead on sustainability - in research, teaching and raising awareness.

The Hague Journal of Diplomacy regularly updates its digital bookshelf with recommendations of recent books on diplomacy, global affairs, and international studies.
