Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.

This thesis focuses on the study of transient and variable radio sources in the universe.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

The Low Frequency Array enables studies of low-frequency carbon radio recombination lines with unprecedented sensitivity, spectral and spatial resolution.

Does a mid-season fire impact invertebrate populations?

This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.

This thesis has described novel synthetic methods to produce a variety of (glyco)peptides and their application in the study of various immunological processes.

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

SEAtrans: an interdisciplinary research project that aims at studying the dynamics and processes of transitions in society-nature interactions in Southeast Asian societies.

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.

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

Religious Studies at Leiden University allows you to study a broad spectrum of religions and their manifestations.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.
