On 2 March 2020 the report Kind in proces: van communicatie naar effectieve participatie (Children in proceedings: from communication towards effective participation) was published. This multidisciplinary research report is the outcome of an inspiring collaboration between various departments at Leiden…

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…

The Faculty of Humanities is known for its diversity of research fields which all engage in innovative and high-profile research. In the new edition of Perspectives on the World: Education and research within the Faculty of Humanities, students and academics elaborate on their academic prowess.

In Perspectives on the World,reflections of 2014-2015, students and staff talk about the research they have been working on during the past academic…

This project aims to identify which aspects of exploring a novel environment produce beneficial effects on memory. The effects of novelty will be investigated across the lifespan, including children, adolescents and older adults.

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…

Have you ever stood in front of an abstract artwork and thought: “a monkey could have done that!”. As it turns out, you are wrong.

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…

As we are working very hard to make our University more green, it is of upmost importance that you join us in our battle and start increasing the local biodiversity from your own house! Every bit will help, it is beneficial for you own mental health and most importantly it is fun! We have created this…

The university is making its campuses future-proof with measures for climate adaptation and biodiversity. You can read in the Sustainability Implementation Agenda 2023–2026 how we harvest rainwater, limit heat stress and make more room for greenery.

The specialisation Museum Studies focuses on the art museum and places it in an artistic, cultural, social and political context. Our courses, taught by art historians and museum experts, reflect on the latest academic debates and the latest insights from the working field.

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…

The goal of pre-clinical development is to bridge the transition from lead compounds to clinical candidates by comprehensively characterizing safety, efficacy, and pharmacological properties. Once a lead compound demonstrates promising activity in disease models, it enters pre-clinical development where…

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

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.

Investigating the intercultural connections that shaped practices of knowledge production in colonial Dutch Brazil.

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

This project studies the roles of prehistoric foragers in past ecosystems to establish the character of past “natural” landscapes and enhance the management of current ones.

Have you spotted the special voting bins on campus yet? Send us your suggestions for challenging, non-scientific questions and who knows? Your burning question might just be the next butt-kicker!

The Sundanese people, the largest ethnic group in West Java, have been using traditional medicine for a long time. Known as ubar kampung, Sundanese indigenous knowledge, beliefs and practices of traditional medicine are based on local people’s knowledge and use of Medicinal, Aromatic, and Cosmetic (MAC)…

How can we monitor and protect biological and cultural diversity in Suriname best? What can we learn from local knowledge and customs associated with biodiversity? How can we understand current species, acoustical, behavioural, and ecological diversity from an evolutionary perspective? Can we predict…

Development of Comprehensive and High-throughput metabolomics techniques and Clinical applications of (pharmaco)metabolomics

Leiden researchers are helping develop safe COVID-19 vaccines.

Supervisor: Maarten Doornbos

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

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…
