Bringing together scholars from a broad range of theoretical perspectives, The Language of Argumentation offers a unique overview of research at the crossroads of linguistics and theories of argumentation.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Methods for accurately computing the interaction of molecules with metal surfaces are critical to understanding and thereby improving heterogeneous catalysis.

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

The Leiden Institute of Physics (LION) offers bachelor and master level education in physics at Leiden University.

Does the sitter have agency in the making of a photographic portrait? And if so how?

On 27 November 2015 Prof. Dr. Grzegorz Rozenberg receives his sixth Honorary Doctorate.

This project investigates the role of art in the public and academic debate on biosolar energy

This study investigates how the tenure of security (proxied by both inter- and intra-party electoral advantage) affects the engagement and political performance of members of parliament.

Explore how skateboarding functions as a prefigurative learning tool in 'Skate/worlds.' This volume examines skateboarding's therapeutic potential, its role in queering and decolonizing education, and its impact on parenting and care work through perspectives from writers, educators, and activists.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

KNOWMAK project aims at developing a web-based tool, which provides interactive visualisations and state-of-the-art indicators on knowledge co-creation in the European Research Area (ERA).

Is criminal disenfranchisement compatible with a democratic political order? This article considers this question in light of a recently developed view that criminal disenfranchisement is justified because it expresses our commitment to democratic values.

New technology offers many new possibilities for research, such as on dementia. ‘Organ-on-a-chip’ is a new technology in which small bits of organ are grown out of stem cells on a small plastic plate. A small piece of blood vessel, heart or nerve offers many new possibilities for research, such as…

Composer Paul Craenen (1972) is actually a pianist, but as part of his PhD ceremony, he performed a composition on PVC pipes. Craenen studies the position and role of the body in music. ‘I am interested in what precedes the resulting sound’.

Assessing the feasibility and legitimacy of the current model of global tax governance and the role of the OECD and EU in international tax law-making.

On Monday June 15 Prof. Dr. Grzegorz Rozenberg received his fifth Honorary Doctorate.

Theoretical research does not always give us the right solution to a problem in society. This message, loud and clear, is delivered during the final presentations of the Master Honours Class 'Social Innovation in Action'.

Where in the model of contemporary art, which can be described as a hybrid and joint undertaking between artists, institutions, curators, theory and discursivity, is the actual 'object' of art located and generated? Where and by whom and in what configuration of positions is it produced? Who or what…

We don’t understand how some materials become superconducting at relatively high temperatures. Leiden physicists have now found a surprising connection with auxiliary black holes. It enables us to use our knowledge of black holes on the mystery of high-temperature superconductivity. Publication in Nature…

In the specialisation Child and Adolescent Psychology , part of the Master in Psychology, you develop practical skills in assessing and managing developmental psychopathology.

In the Dutch healthcare system, only MHC psychologists (GZ-psychologen) are licensed to practice psychology unsupervised.

This subproject, carried out by post-doctoral researcher Dr. O. Nieuwenhuyse, investigates changes and continuities in the functional, social and symbolic uses of the material culture, c. 6800-5800 BC. A contextually oriented approach is adopted, which pays attention to the local socio-economic and…

To be eligible for Theoretical Philosophy at Leiden University, you must meet the following admission requirements.

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

The master's specialisation Astronomy and Cosmology at Leiden University covers all aspects of modern astrophysics, including observation, interpretation, simulation and theory. This programme is essentially based on combined research in astronomy and physics and is therefore open for students with…

The programme will give you the opportunity to choose from a broad range of topics to study. You will be part of an international multidisciplinary research team at our institute.

The MSc programme Physics offers 5 research-oriented specialisations where you can focus on Theoretical Physics, Quantum Matter and Optics, Biological and Soft Matter, or Cosmology. You can also combine Physics with education, management or science communication.
