On Tuesday 19 December 2017 Anneloes Kuiper-Slendebroek defended her doctoral thesis 'Rechter over Grenzen' which deals with the application and interpretation of international law in Dutch private law. Supervisor is Martijn Polak, co-supervisor is Jeroen van der Weide.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

Our Mission: To optimize human well-being within the constraints of planetary boundaries through innovative research, education, and partnerships that advance sustainable production and consumption. We strive to remain global leaders in developing and applying systems-based approaches, methodological…

This research project seeks to understand the dynamics in the relationship between social media, mobile telephony and the social fabric under duress in Africa's mobile margins. It combines studies on mobility/migration, conflict and communication in an attempt to uncover these new dynamics, which have…

Material Crossovers

The demolition of the high-rise building is ready. The remaining debris are removed and the area is cleared. For the demolition, the University applied the BREEAM evaluation method at the level of ‘Excellent’, which means that the demolition operations were carbon neutral and did not cause any form…

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…

The Academic Language Centre has developed 19 video clips on Academic Skills. The videos are divided into three categories. Watch them below for a good start to your studies!

This third issue of Ex Novo gathers multidisciplinary contributions addressing mobility to understand patterns of change and continuity in past worlds; reconsider the movement of people, objects, and ideas alongside mobile epistemologies, such as intellectual, scholarly or educative traditions, rituals,…

Open Science and Recognition & Rewards come together in this university-wide programme.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

An Investigation into the role of copper-alloy craft production in the early medieval economy of northwest Europe.

To what extent can contingent, formative feedback in lectures, facilitated by web-based ICT, increase students’ self-efficacy and (academic, behavioral, and cognitive) engagement? And how are self-efficacy and engagement influencing students’ performance and course evaluations?

The central aims of this project are to establish the shapes of the various urban hierarchies existing in the provinces of the Roman Empire and (especially) to use the quantitative properties of these hierarchies to shed new light on levels of economic integration.

Port City Futures is an initiative of the Leiden-Delft-Erasmus Universities collaboration. The program investigates the evolving socio-spatial conditions, use and design of port city regions, in particular exploring areas where port and city activities occur simultaneously and sometimes conflict.

Management of Impacts on Biodiversity: What are the effects of light pollution from cities and bridges and noise pollution from passing vessels and nearby road traffic on migratory fish passage and spawning in rivers?

1) The in-use construction material stocks of the BRI projects and their temporal and spatial distribution. 2) Environmental impacts (e.g. carbon emission and biodiversity loss) of constructing BRI projects. 3) Socio-cultural impacts of the BRI projects.

The current migration flow into Europa demands effective measures. Leiden experts examine whether these measures are legal and hold up a mirror to policy-makers.

To ensure that the growing global flows of labour migrants are guided correctly, we need knowledge. Why do people leave home, why do they go to specific countries, and how can that choice be influenced? And what are the consequences of their leaving for the people who stay?

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

On the 22nd of April, Liszt Vianna Neto successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Liszt Vianna Neto on this achievement.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

Material culture and the role of rural communities in exchange systems of the eighth and ninth centuries

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

Alzheimer's disease (AD) is the most frequent neurodegenerative disorder and the primary cause of dementia. The neuropathological features of AD include the occurrence of senile plaques, neurofibrillary tangles, decreased synaptic density, and loss of neurons. An obstacle in the study and treatment…

This article reviews how external expertise supports intelligence production and crisis decision-making with Germany's response to the Russio-Ukrainian war.

Port cities develop at the intersection of international trade and commerce and at the interface between sea and land. What does the future of port cities look like with urbanization, sea level rise, new migrant flows and the disappearance of old industries? This is addressed in the minor (Re)Imagining…

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

How to facilitate the translation of science into innovation

The Graduate School Management (GSM) module is a registration and monitoring system for PhD candidates and their supervisors. All information is stored uniformly and made accessible in one place. The GSM module is part of the LUCRIS system. Converis is the software behind LUCRIS.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

We investigate emergent structures and dynamics of soft materials self-assembled from microscopic constituents.

On the 23rd of June Arianna Sacco successfully defended a doctoral thesis and graduated.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.
