In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

This thesis attempts to establish a dialogue between the modern and the medieval traditions in logic, by means of ‘translations’ of the medieval logical theories into the modern framework of symbolic logic, i.e. formalizations.

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

We aim to develop a microfluidic platform that can parallelize testing the performance and characteristics of pure, mixed and environmental bacteriophage samples.

What is the effect of pesticides, fertilizers or plastic on water quality? And how do wind and rain affect the data? These are just some of the things that Leiden environmental scientists study in the 32 ditches of the Living Lab.

Can zebrafish provide a fast, sensitive in vivo vertebrate model for identifying novel mechanisms of Ewing sarcoma progression and for development of new anticancer compounds in a time- and cost-effective manner?

This research cluster explores processes of cultural creation, reception and transformation within a wide range of societal contexts from the early Middle Ages until c. 1800.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The making of sacrifices seems part and parcel of any elite sportsperson’s life. Remarkably, the insights that we find in the current literature in social sport studies are not able to make sense of the references to sacrifice in the data that emerged in the context of this study on the social significance…

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…

Can we predict fluctuations in suicidal ideation in a person’s daily life, from hour to hour?

The ARTIVES project studies imaginaries of diversity portrayed by artists in Lisbon and Rotterdam in their films, performances and (oral) literature with the aim to explore their transgressive potential of opening up possibilities of thinking differently about migration-related diversity. Their stories…

Special amplifying agents can make MRI scanners and NMR techniques hundreds of times more sensitive. Leiden physicists have now found a method to test their efficiency. More sensitive MRI scans could for example improve our understanding of cystic fibrosis or Parkinson’s disease. Publication in PCCP…

The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

This thesis describes a study from both a theoreticaL and an experimental point of view.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…

In this article, Lianne Visser contributed to the understanding of why collaborative governance is a challenging response to wicked problems.

As part of Nexus 1492 Subproject 4: A Future for Diverse Caribbean Heritages, which seeks to shed light on how local communities interpret and engage with heritage in the present day, this doctoral study aims to gain insight into how indigenous heritage is represented in the school curriculum for social…

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.
