Op 16 juni 2020 verdedigde Andrea Varga haar proefschrift 'Establishing State Responsibility in the Absence of Effective Government'. Het promotieonderzoek is begeleid door promotoren prof. dr. N.J. Schrijver en prof. dr. F. Baetens (University of Oslo).

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…

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

Control of infectious diseases poses continuous challenges for human health.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

The emergence of complex diseases resulting from abnormal cell-cell signaling and the spread of infectious diseases caused by pathogens are significant threats to humanity. Unraveling the dynamic mechanisms underlying cell-cell signaling and infectious disease spreading is crucial for effective disease…

Migratie en criminaliteit staan maatschappelijk volop in de schijnwerpers. Binnen het instituut voor Strafrecht en Criminologie heeft onderzoek op dit terrein zich de laatste jaren sterk ontwikkeld. Het begrip Crimmigratie staat daarbij centraal.

Does knowledge of environmental performance change farmer's behaviour?

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…

Het belangrijkste doel van dit onderzoek is om de steden van het Romeinse Nabije Oosten in de keizertijd in kaart te brengen, met een focus op locatie, stadsgrootte en stedelijke kenmerken, om de vorm van het stedelijke systeem en de niveaus van integratie te bestuderen.

De organisatie voor Economische Samenwerking en Ontwikkeling (OESO) heeft in samenwerking met het Inter-American Center of Tax Administrations (CIAT) op 27 november 2023 een wereldwijde online Tax Morale Workshop georganiseerd, waar Esther Huiskers-Stoop van de Universiteit Leiden en Diego Quiñones…

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

Staf en studenten bij het LUCSoR werken nauw samen met maatschappelijke partners. We werken mee aan de ontwikkeling van onderwijs over religie, levens-beschouwing en burgerschap, en adviseren overheidsinstanties en religieuze organisaties.

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…
