The emergence of the Köprülü household that imprinted its stamp on the latter half of the seventeenth century in the Ottoman Empire. What is the power struggle they carried out against Ottoman dynastic power?

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

How do interest groups in the Netherlands use strategic litigation to bring about political, social or legal change, and how does this strategy compare to other, more classical, ways to influence policy?

How many species of plants, animals and fungi live in urban nature? in 2026 are Leiden, Leiderdorp, Oegstgeest and Katwijk observing and recording how many unique species there are, to put the state of urban nature on the map. Together everyone from May 1st till 30th of June will record every spider,…

Leiden University and LUMC benefit from unique knowledge gained from research and teaching about healthy lifestyles. We want to bring this knowledge together into one place, and we want to share it even more effectively than we do now.

How do we explain the fact that certain areas had many large cities, while other areas were studded with large numbers of small towns and yet other areas had very few urban agglomerations of any kind?

Modern scientific discovery increasingly depends on High-Performance Computing (HPC) systems that combine traditional processors with specialized accelerators such as GPUs.

Leiden University works with primary and secondary schools in Leiden and The Hague.

Procedural administrative law in a constitutional comparative law perspective

The research area of this division is focused on the development of novel therapeutic modalities and novel concepts in early drug discovery, in order to better predict ligand-target interactions.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

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

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

With an ageing population it is becoming increasingly important to find means to repair cells, tissue and organs through regenerative medicine.

Urban development and lack of appropriate management has been threatening the archaeological site of Tell Balata. In order to save it from further destruction, in 2010 the Tell Balata Archaeological Park project was started.

The aim of this project is to develop accurate but interpretable ensemble learning methods for high-dimensional multi-domain data.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

The development of literary celebrity by focusing on five famous Dutch authors from the nineteenth century

The blended flipped classroom is a partially online, partially offline course to teach social science research methods. Online, students watch video lectures, do readings, and complete short exercises to acquire basic knowledge of research methodologies and academic skills.

With the recent rise and fall of IS, academics and policy makers around the world are expressing concerns about the fate of children of former foreign fighters. Will they follow in their parents’ footsteps? In this paper, Layla van Wieringen, Daan Weggemans and Marieke Liem argue that in light of this…

Sheltering is an immediate human need and determines well-being andhealth.

This study seeks to analyse how job stress could be the result of performing administrative tasks

A linguistic test of hypotheses rooted in genetics and archaeology.

It is difficult to deny the value and importance of human rights, and yet their application in the context of climate change is increasingly contested. While some argue that it is difficult to establish the violation of human rights by climate change processes, others contend that human rights are anthropocentric,…

The archaeology domain produces large amounts of texts, too much to effectively read or manually search through for research. To alleviate this problem, we created a search system (called AGNES), which combines full text search with entity and geographical search.

For a Union closer to its citizens: social psychological insights into EU-level redistribution and perceived legitimacy.

A project on phonology, phonetics, and the space between them.

Public leadership received increasing attention, but we still do not understand how the context of public leaders affects leadership. This research project delves into public leaders’ perceptions of the leadership situations they find themselves in, which are characterised by multiplicity – one could…

The largest structures in the Universe are clusters of galaxies. Each can contain hundreds to thousands of galaxies.

We are developing biology-driven platforms to measure metabolites based on liquid chromatography-mass spectrometry (LC-MS), gas chromatography-MS (GC-MS), and capillary electrophoresis-MS (CE-MS).

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…

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments. We apply our technology and methods to find biomarkers for key disease pathways and toxicity in clinical studies and in…

In 2023, the OSCL, together with the University Library and Academia in Motion, ran a survey to better understand the state of Open Science at our university. In this year's follow-up, we are asking you to give your input, so we can jointly develop how Open Science evolves in our university.

This is the first comprehensive commentary on a section of Xenophon's Anabasis in English for almost a century.

The topic of this study is the portfolio that is being used in a teacher education institute as an instrument for stimulating reflection on their development as teachers by student teachers.

The experiences of ethnic ‘Other’ females have – until recently – been widely overlooked in the study of sport. There continues to be a need to produce critical scholarship about ethnic 'Other' girls and women in sport and physical culture, in order to represent their complex, multifarious and dynamic…

In this article, Adriana Cerdeira and Dovile Rimkute explore how certain dynamics shape banks' behaviour.

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…

I would like to investigate what are the philosophical and practical consequences a reappraisal of the 17th-and 18th-century concept of taste may have for general and historical performance practice.
