What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

Statistical distributions in LCA and converting between different representations of these distributions.

This PhD project develops and applies a GIS procedure to use legacy survey data in settlement pattern analysis. As part of the research by the LERC project (NWO, Leiden University, KNIR), legacy data produced by surveys in central and southern Italy are examined in a comparative framework to investigate…

The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

In several Mediterranean regions archaeological sites have been mapped by fieldwalking surveys, producing large amounts of data. These legacy site-based survey data represent an important resource to study ancient settlement organization. Methodological procedures are necessary to cope with the limits…

Patterns of paleomobility in the Caribbean were studied through an inter-disciplinary approach using a combination of archaeological, osteological, mortuary, and isotopic data.

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.

Another research line is the development of a spatial CNS drug distribution model, by ultimately including the 3-dimensional anatomical organization of the CNS.

The Research Group “Diplomacy and Global Affairs” focuses on topics such as changing global power constellations, (international) diplomacy, conflict prevention and resolution, the work of actors such as international, multilateral, regional and non-governmental institutions, and research on the prevention…

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

On May 17th, Arthur Crucq succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Arthur on this great result.

This research project is supported by an NWO Aspasia grant, DeepDish TV, crowd-sourced funding, and the Democracy and Media Foundation.

Over the last decades, income inequality has increased globally. How do social policies affect this increasing trend? How do international trade and technological progress affect inequality? What is the profile of income inequality in China?

Under what circumstances is politicization more likely to occur than others, and what impact does politicization have on government legitimacy and performance?

The Global Abolitionisms Network has been established to link scholars from across the world and across disciplines who are working on antislavery activism and abolitionism.

For a first time the atlas maps the soil biodiversity of the entire planet, and provide s comprehensive analysis of human-induced threats to soil organisms and soil functioning, facilitating development of new policies to protect soil and soil organisms.

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

Historical migration studies have long focused primarily on the European and Atlantic worlds. In this programmatic and long term project, we aim to broaden the perspective to include the full migration experience of the non-Western world.

What happens to electrical waves that have to cross gaps in insulation material around nerves in the human body

International trade plays a critical role in global food security, with global consumption having highly localized environmental impacts.

Colonial and Global History 1200-present explores the global circulation of people, goods and ideas during early-modern and modern times. Taking a comparative perspective, this program investigates the development of transnational and transcontinental connections and their impact on the making of identities,…

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…

How does global change across time and space lead to convergence and loss of variation or increasing diversity and conflict?

The Summer School ‘The European Union, the United Nations and Global Governance’ will focus on a range of topics relevant to interactions between the European Union (EU) and the United Nations (UN) and the EU’s role within current patterns of global governance.

Globalization, migration, technological innovation and climate change pose challenges to citizens in European countries. These challenges test the limits of cross-national and cross-generational solidarities, touching upon the very foundations of governance and society. This research program aims at…

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

Global Challenges is the research programme of the Leiden Institute of Cultural Anthropology and Development Sociology.

Political Scientist Gisela Hirschmann (Leiden University) asks how international organisations can be compelled to comply with respect human rights. She finds that this is done through ‘pluralist accountability’: external third parties such as courts, NGOs, or regional organisations holding international…

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

The specialisation Global Conflict in the Modern Era of the master’s in International Relations at Leiden University engages you with the scholarly debates about global conflict today and in the recent past.

The modern-day Caribbean is a stunningly diverse but also intricately interconnected geo-cultural region, resulting partly from the islands’ shared colonial histories and an increasingly globalizing economy.
