The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Galikyan’s dissertation examines how the multidimensionality of learner­learner interaction data and the multifacetedness of learner-learner interaction itself impact the measurement of learner-learner interaction in digital learning environments.

Lipid nanoparticles (LNPs) have enabled the success of mRNA vaccines but remain limited in broader therapeutic use by challenges in delivery efficiency, targeting, and mechanistic understanding.

In tracing intra-site, local and regional craft networks in Late Bronze Age Tiryns (Greece) the project aimed to understand technological changes, (dis)continuities and social practices from the Late Palatial until the Post Palatial periods in Mycenaean Greece.

There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

The aim of this research is to gain insight into the approaches of learning to teach. Teacher learning processes, feedback in novice-expert interaction and the impact of the interaction are explored.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

A defining fixture of our contemporary world, video games offer a rich spectrum of engagements with the past.

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

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?

Are there general principles or values that should govern our actions as moral agents and/or as political subjects?

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

Toll-like receptors (TLRs) are central components of the innate immune system, functioning as pattern recognition receptors that detect microbial- and damage-associated molecular patterns and initiate antimicrobial and inflammatory responses.

Smartphone behaviors are so common but how does the brain generate this behavior? The Cognition in the digital environment laboratory (CODELAB) investigated the brain activity surrounding smartphone interactions with the help of Artificial Intelligence. According to their research, the brain fluidly…

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

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

A new publication that brings together perspectives on language contact phenomena across temporal and spatial dimensions.

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

In this thesis, classes of strongly interacting quantum field theories, have been studied.

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…

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.

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 thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

The primary goal of this research is to deepen our understanding of substrate-enzyme interactions in Glycoside hydrolases. For this purpose, Bacillus circulans xylanase (BcX) has been selected as a well-established model to examine the Michaelis complex and glycosyl-enzyme adduct.

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

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