Unravelling networks of human mobility and exchange of goods and ideas from a pre-colonial, pan-Caribbean perspective

Studying Physics is an exciting journey through the foundations of nature: from the infinitesimal (particle physics) to the grandest scale (cosmology). Physics is a varied study programme that provides a solid foundation in theory and experimentation, with attention devoted to their practical applic…

The GTGC programme advances interdisciplinary research on how we govern – and could govern – major world-scale changes in contemporary society. These global transformations and governance challenges cover the themes listed here. The distinctions are not rigid, of course, and affiliated researchers often…

To support interdisciplinary research on today's world-scale changes and governing challenges, the GTGC programme awards a number of seed grants to scholars at Leiden University collaborating across different faculties and institutes. Here you can find out more about current projects and open or upcoming…

Crises like climate change and loss of biodiversity pose serious challenges for public governance, from the local to the global scale. With the Centre for Governance of Sustainability we contribute to addressing these governance challenges. Our focus is on how policy processes and governance practices…

Can the (industrial) herbal extraction process be mathematically described and can this model be used to optimize the extraction in terms of quality and economical parameters?

Edited by Dr. S. Arnoldussen and Prof. dr. H. Fokkens

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

On 7 December 2021, Georgina Kuipers defended the thesis 'Beschadigd vertrouwen'. The doctoral research was supervised by Prof. W. den Ouden and Prof. M.A. van der Steen (EUR).

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

The overall aim of CAM-PaC is to contribute to solving the socioeconomic and health challenges of PDAC by an integrative and systematic functional analysis of pancreatic cancer candidate genes. CAM-PaC will develop novel cellular and animal models, as well as novel strategies to analyse and integrate…

The aim is to discover where differently shaped metal nanoparticles distributes in Danio rerio, linking the distribution with genomic responses and so come up with a Mode of Action.

Research on the process of artisanal and small-scale mining (ASM) in West-Africa

In this study, we evaluated the influence of supercritical carbon dioxide (scCO2) spray drying conditions, in the absence of organic solvent, on the ability to produce dry protein/trehalose formulations at 1:10 and 1:4 (w/w) ratios.

Latent variable modeling of students' solution strategies and performance

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Our DNA molecules are packaged by proteins in compact structures. The aim of this project is to understand how modern gene editing techniques nevertheless get access to their target in the DNA.

How to ensure the environmental and economic benefits of circularity transition at macro-scale?

What would be the environmental performance of the Carbon4PUR technology at industrial scale in the future?

Since the emergence of humankind people have maintained social contacts and traveled widely, establishing interaction networks in which goods are traded and ideas are transmitted, increasingly on a global scale.

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

This thesis reports on the influence of induction programs on beginning teachers’ well-being and professional development, and the essential characteristics of an induction program. These topics were explored by means of an interview study and large scale survey study.

Dr Carwyn Morris (LIAS) was awarded the British Academy Global Convening grant, as part of an international consortium with 19 colleagues.
