Andrew Hoffman (CADS), Mark Westmoreland (CADS) and Yasmin Ismail (CADS) have received a KIEM grant of € 10.000 for their project 'CARMA: Community Archive and Repository for Multimodal and Artistic Research'. The grant will be used to create a 'living laboratory' that helps researchers, data management…

Responsible Research and Innovation (RRI) implies that societal actors (researchers, citizens, policy makers, business, third sector organisations, etc.) work together during the whole research and innovation process in order to better align both the process and its outcomes with the values, needs and…

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

Disinformation has become a popular subject of study and debate. A plethora of publications and policies have emerged, aiming to analyse and curb the negative consequences of unwanted communication.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

The aim of this thesis was to study the link between hearing loss, language skills, and social functioning in deaf and hard of hearing (DHH) children. Sufficient language skills are an essential prerequisite to develop appropriate communication skills, in order to join in conversations with others.…

It is often claimed that social media can contribute to democratic decision-making by bringing politicians and citizens into dialogue with one another. But is this potential always realised, and how? Most researchers look at politicians and their online communication strategies. In this New Media &…

Scientists have discovered that starlings and parrots can imitate the complex sounds of Star Wars droid R2-D2 remarkably well. Their study reveals how the structure of a bird’s vocal organ determines its vocal abilities – and how citizen science helps uncover it.

We want to be an engaged community where we feel heard and enjoy working together. But how do we have an open conversation about difficult topics?

Many members of Chicago's P'urhepecha community did not even know they lived a stone’s throw from some of their own historical heritage. Researcher Kate Bellamy organised a meeting to introduce them to books hundreds of years old.

On 14 November 2025, representatives from several organizations across the publishing reform and research assessment reform communities gathered in Pisa, Italy, for a workshop aimed at identifying and advancing joint actions to strengthen both movements.

Visual art played an important role in the development of cooperative human behaviour. This is the finding of Larissa Mendoza Straffon, a PhD candidate in archaeology, whose dissertation explores the biological and psychological foundations of visual art.

A novel in vivo model system for studies on glucocorticoid resistance

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

Published by Brill Nijhoff and written by leading experts including national judges, academics and practitioners East African Community Law is the first comparative as well as open access textbook on EAC law. The book provides a key resource for the research, teaching, and practice of EAC law. It also…

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,…

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…

As part of the LIAISON Research Project, Eduard Fosch-Villaronga and Hadassah Drukarch organised a workshop at the European Robotics Forum (ERF 2021) to engage the broader community in the projects’ goal of liaising robot development and policymaking.

The project ‘Between the Holy Land and the World’ proposes a connected history of the Christian communities in the Near East (1900-1948) by means of a study of unpublished Franciscan and Dominican photographic collections.

'What nature made isn’t necessarily an optimized medicine to use in the human body,’ says Professor of Biological Chemistry Nathaniel Martin. That’s why a group of Leiden researchers is making a chemistry-based improved version of the frequently used antibiotic vancomycin. They received an NWO NACTAR…

How can we make the information in handwritten historical research reports accessible and searchable? Data scientists at Leiden University are working with other universities on a method that will improve access to cultural heritage.

Key publications of the Predictive Pharmacology group.

Our leadership model consists of four competences that align with our core values. Each leadership competence expresses two opposing qualities. The goal is not to prioritise one of these qualities over the other, but to find the right balance between them. Effective leadership starts with awareness…

Target selectivity is an important aspect of any drug molecule, and certainly a parameter to be optimized. That is not trivial for a number of reasons. First of all hundreds of drug targets (receptors, enzymes, ion channels) exist, and no single lab in the world has assays for all of them.

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

What are the host immune defence mechanisms that control intracellular infections and how are these subverted by pathogens?

What was the environmental impact of the industrial mining revolution that transformed southern Africa? Specifically, what was the impact of industrial mining when viewed from a more than human multi-species perspective?

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