A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land that we could use to produce energy and remove carbon from the atmosphere. Leiden…

Prediction of human (CNS) target site concentrations in health and disease In the vision of Prof. de Lange we will only be able to predict human (central nervous system, CNS) target site concentrations and effects if we perform systematic, condition-dependent, integrative, and strictly quantitative…

Because we cannot directly ask babies about what they know or what they are thinking about, we must find smart and baby-friendly ways to figure it out! Below you can read about the different methods that we typically use in our studies.

He’s a fast and animated speaker, which is only logical because Gerard van Westen is driving an express train. His destination? A virtual human, consisting of algorithms that predict what an administered substance will do in the body. The train is already a long way down the line and the pharmaceutical…

A novel in vivo model system for studies on glucocorticoid resistance

The master’s programme Media Technology (as of September 2025: Creative Intelligence & Technology) at Leiden University focuses on creative exploration as well as the understanding of science and technology.

The specialisations Art History and Museum Studies both engage in critical perspectives and in current practices and the development of a professional network. The specialisation Museum Studies focuses on the art museum and places it in an artistic, cultural, social and political context. Our courses,…

The specialisations Art History and Museum Studies both engage in critical perspectives and in current practices and the development of a professional network. The specialisation Art History puts emphasis on the analysis of art works within a museal and curatorial context. Our courses, taught by art…

A three-volume standard work on galls in Europe. Author Johannes C. (Hans) Roskam is associate professor emeritus in Evolutionary Biology and currently guest at Leiden University.

Assesses the importance of Merleau-Ponty to current and ongoing concerns in contemporary philosophy.

The Cognitive Psychology Unit has two main research lines, which focus on basic cognitive (neuro)science and applied cognitive psychology.

This project investigates the transposition of natural historical material, knowledge and vision, between different media (collection, scientific drawing, academic texts, the visual arts and/or literature) – a transmission that happens in the borderline between the traditional, emblematic worldview…

Identification and characterization of components of DNA repair pathways and their role in Agrobacterium T-DNA integration and repair of CRISPR/Cas induced DSBs.

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

1000 Years of World History in 100 Old Maps.

Százhalombatta-Földvar is a Bronze Age fortified tell settlement on the right bank of the river Danube, 30 km south of Budapest in Hungary. It is one of the best preserved temperate climate tells in Europe and well-known for the extraordinarily rich data it produces. Since 2014 Leiden students are welcomed…

What is the mechanism of action preceding a physiological effects induced by metallic nanoparticles?

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

This doctoral project, entitled Sinophone as Method: Reimaging Chinese Cinema in the Global Era, aims to explore the intricacies of knowledges and practices with regard to notions of China, Chinese, and Chineseness.

This subproject of 'From Homo Economicus to Political Animal' will be on ancient analogues for modern-day “ersatz economics”, the economics of the “man in the street”.

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…

In science, it is of vital importance that multiple studies corroborate the same result. Researchers therefore need to know all the details of previous experiments in order to implement the procedures as exactly as possible. However, this is becoming a major problem in neuroscience, as animal studies…

Utilization of plant-originated products as new antibiotics

LIAS has a School of Asian Studies (SAS), a School of Middle-Eastern Studies (SMES) and a School of Religious Studies (LUCSoR). These designations, and the fields within them, remain foundational to our work. At the same time, the academic community benefits from the presence of cross-regional networks…

Anxiety disorders, like specific phobias, are among the most prevalent mental health disorders that may hinder children in their development. Cognitive Behavioral Therapy (CBT) is considered an effective treatment for childhood anxiety. After treatment, children are encouraged to practice at home with…

The precise psychobiological mechanisms leading to chronic physiological stress responses have not been sufficiently explained, although stress is a major risk factor for disease and early death. A problem for conventional stress theory is that most of these responses seem to occur in situations without…

Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…

How does the extracellular matrix coordinate endothelial cell behavior during angiogenesis, and how do metabolic waste-products and matrix-degrading enzymes produced by the tumour modify the extracellular matrix so as the change the cellular coordination?

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

This report investigates the different approaches in the authorization process of GMOs for commercial use in the European Union and the United States of America. Three main aspects are considered and analyzed as potential causes of differences in the authorization process of GMOs for commercial use.…

Memoria de un Paisaje Sagrado

North, Middle and South America together constitute the single largest area in World Archaeology that is taught as a single focus. It is also the only major world area that saw societies develop from hunter-gatherers to early empires entirely independent from developments in Eurasia & Africa. It is,…

During the Leiden Science Family Day, you can take part in various workshops. You can also watch various demonstrations. Where will you go?

The research group Science Communication and Society has been physically within the Institute of Biology (IBL) since 2012 and has become a formal part of the institute in 2018. The mission of this group is understanding how science communication works to improve the interaction between science and s…

Children with a specific phobia are excessively afraid of certain objects, animals or situations. Specific phobias are common in children, but they can make the child’s life at home, school and outside quite difficult. Together with a large international team, we developed the KibA-program to help children…
