This is a joint PhD of the Faculty of Social and Behavioral Sciences at Leiden University and the Evolutionary Ecology Group at Antwerp University.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

An archaeological case-study of the Pointe des Châteaux, La Désirade and Les Îles de la Petite Terre micro-region, Guadeloupe, F.W.I.

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

What is Interaction between Legal Systems (ILS) and what does it entail as research profile area at Leiden Law School? More on this at the kick-off event of ILS 2.0. This will take place on Wednesday 26 October 15.00 – 17.00 in the Grotiuszaal (A051 KOG). The afternoon will be closed with drinks at…

Can we build a biosensor to detect neuroblastoma markers in urine using the chemotaxis system in E. coli?

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 &…

Curved single crystals provide variable, but well-defined surface structures.

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

The Netherlands is losing plant species that rely on pollination by insects. Leiden environmental scientist Kaixuan Pan demonstrates this after analysing 87 years of measurements from over 365,000 plots. The news is alarming for our biodiversity and food security. ‘75 per cent of our crops and 90% of…

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

This project employs a systematic experimental approach to examine the interaction of these two hitherto independent lines of research (tone sandhi and focus realization) in six dialects of Chinese, which lie on a continuum between dialects with dense tonal distributions and sparser distributions. In…

This project examines the intriguing relationship between Greek literary criticism and Latin literature in Rome (first centuries BC and AD).

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

Although many studies have addressed democracy in education around the world, so far research on democratic education in the context of communist society has been scarce. In the current study, we aim to clarify the concept of democratic value and its manifestation in Vietnam’s schools. In addition,…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

The project concerns the nature, the usages and functions of pictographic systems in relation to writing in societies with (restricted) literacy.

Most of the vast Tibetan literature was authored by monks. They were Buddhists par excellence, educated in a system in which Indic- and Indian-inspired texts played a pivotal role. What they wrote was primarily religious or philosophical in nature, but also extended to ‘secular’ topics. Through the…

Lecture, CHiLL series

In November of last year Global Interactions made offers to five out of nearly 90 applicants for our grant-writing postdocs. We are pleased to announce that all have accepted and will be joining various Leiden institutes this year. The five postdocs are Katia Hay, Johannes Müller, Maria-Paz Peirano,…

We aim to create an innovative e-learning and virtual reality training that helps healthcare providers to optimize placebo effects and minimizes nocebo effects via their communication.

The purpose of this study was to investigate the formation and growth kinetics of complexes between proteins and oppositely charged polyelectrolytes.

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

On Wednesday 26 October the kick-off event of the research profile area ‘Interaction between Legal Systems 2.0’ (ILS) took place. Speakers explained their understanding of the concept of ILS and the activities and opportunities of ILS 2.0 for the faculty were set out

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…

Dr. Joanita Vroom has been awarded a Breed Grant by the Leiden Global Interactions research profile to support the realisation of her project ‘Shifting Empires, Cultural Encounters. Mapping Material Culture and Foodways in the Medieval & Post-Medieval Eastern Mediterranean and Adjacent Near East (600-1900…

Graphene and other layered materials combine into completely new substances. Leiden physicists establish the ground rules for designing such materials by measuring how the layers in the stack interact. Publication on November 29 in Nature Communications.
