What is the relation between brain development and social and cognitive development across childhood, adolescence and adulthood?

Increasing above- and belowground biodiversity in arable leek cultivation to stimulate pest control by natural enemies.

SALTSWAT -- a project which combines the Spaces for Active Learning & Teaching and the Support wtih Active Teaching -- began in Mid-2019 and is running in pilot until the summer of 2020. The purpose of the project is to find answers to the question of how to systematically accelerate 'active teaching…

The Leiden Index of Depression Sensitivity (LEIDS) measures cognitive reactivity (CR) to sadness, an aspect of cognitive vulnerability to depression, conceptually similar to rumination.

Can positive peer feedback break the cycle of negative self-relevant cognitive processes and reduce self-reported anxiety in early adolescents?

Do natural soundscapes affect migratory decisions of fishes moving up and down rivers and is this process disturbed by vessel sounds?

We aim to conduct as few animal experiments as possible. We are continually exploring methods to Replace, Reduce, and Refine animal experiments, commonly referred to as the three Rs. Additionally, we assess each study to ensure the implementation of the 3Rs has been maximised. The Animal Welfare Body…

Addressing Global Challenges through International Scientific Consortia

In this research project child language phonology is studied from the perspective of a psycholinguistic speech-production model and this model is in turn studied from the perspective of developmental phonology.

Growing public backlash against international organizations (IOs) and attacks of national political elites on the rule of law increasingly challenge governance by IOs.

The NET-ROL project builds on the EU's definition of the rule of law to investigate the role of networks in law-making, executive decision-making, and the judiciary. It examines how these networks influence the weakening of the rule of law. Through an interdisciplinary perspective, the project explores…

LEGITIMULT examines how Covid-19 measures by governments impact multilevel governance and democratic governance in 31 European countries

The main aim of this project is to investigate the various ways in which language categorizes possession, how these are morphosyntactically encoded across and within languages, and how this distinction should be represented in a model of the language faculty.

The Biomedical Metabolomics Facility Leiden (BMFL) is the core metabolomics facility of Leiden University and the Metabolomics and Analytics Centre (MAC). We offer a highly structured environment for advanced MS-based metabolomics studies and build on fully validated, state-of-the-art assays that each…

What are the biological effects of Chinese herbal medicine in regulation of cancer cell metastasis?

In this project, we aim to develop mathematical models to mechanistically and quantitatively predict the dynamics of cellular stress pathway activation and its relation with toxic effects when cells are exposed to various toxicants.

The research group Corporate Governance and Strategy investigates how, with whom and for whom a firm/corporation creates/captures value, in order to inform practice and rule makers about governance issues. By focusing on the dual character of the firm as an entity by itself but also consisting of stakeholders,…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

When we are in a conversation, how do we know exactly when to respond, and how do we manage to respond so swiftly, yet without interrupting our interlocutors? Can speech melody – in particular utterance final “boundary tones” – help us determine who will speak next, or are these cues too late in the…

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

Does the public speaking anxiety that many youngsters experience originates from specific characteristics in their earlier development?

This research area is focused on the development and application of novel concepts and models in the emerging area of quantitative systems pharmacology (QSP).

The Physics and Biological and Soft Matter master's specialisation is one of the two programmes that Leiden University offers in experimental physics. This programme mainly focuses on Biological Physics and Soft Matters Physics.

Our programmes are known for our scientifically based education and for our open atmosphere.

CADS researchers give methodology their own unique signature through two parallel engagements: (a) teaching and researching the full range of social science methods, from audio-visual engagements, through global ethnography, to statistical analysis; and (b) interrogating these multiple modalities employing…

Leiden’s Institute for History has an exceptionally strong expertise in premodern European history in its global context, with specialists whose interests cover virtually the whole continent.

Methodology & Statistics offers bachelor's courses and a master's specialisation.

‘I would never want to be treated by a computer,’ says Boudewijn Lelieveldt, Head of Radiology at the Laboratory for Clinical and Experimental Image Processing and Medical Delta professor in the Bioinformatics group at Delft University of Technology. No matter how intelligent a system, we have to continue…

Our ability to learn and control movements is essential for engaging in goal-directed behaviour. From buttoning your shirt and driving a car, to cooking dinner and brushing your teeth -- our actions in daily life rely on this ability.

What is the relation between brain development and social and cognitive development across childhood, adolescence and adulthood?

The overarching aim of this theme is to increase our understanding of the mechanisms underlying altered cognitive, affective, and social behavior in relation to mental health problems.
