Both good employer practices and good employee practices are open norms. These open norms can lead to uncertainty about what employers should focus on and what rights (and obligations) employees have in that respect. The objective of this study is to give substance to the norm of good employment practices…

Or imagine that you have Parkinson's Disease, causing your hands to tremble and making it difficult for you…

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

How do tax treaties have to be explained and implemented, and what role does the supranational regulatory process play in this? Which objectives are meant to be used in establishing tax regulations and to what extent are such legislative practices undertaken in a goal-oriented manner?.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

This 48-month project is to contribute to a solid, accessible, domestically owned knowledge base for people-centred interventions aimed at strengthening access to justice in Libya (A2JiL), and to disseminate such knowledge among stakeholders, enhancing awareness and the capabilities required to provide…

Generally, PhD candidates are recruited for specific research projects by public advertisement. In addition, unsolicited applications from high potential candidates with an appropriate master degree are welcomed.

One of the three long-term research interests of our group concerns the Transformation of the Roman World (c AD 450-900).

See below for the full programme and abstracts of all papers.

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

We are all aware of the importance of a healthy lifestyle. However, at the same time we also experience many difficulties when we are trying to change our behavior to become more healthy. For example, more often than not our good intentions to exercise more or to eat fewer unhealthy snacks fail miserably…

The organising committee of the congress 'Social Benefits of Higher Education' has decided to postpone the congress.

This research line is part of the living lab of the University’s Population Health interdisciplinary program, located at the LUMC Campus The Hague, where the Leiden University Medical Center collaborates with the Faculty of Governance and Global Affairs and the Faculty of Social and Behavioral Sciences…

How humans and rats cohabit the cityscape and what consequences this has for both sides of the conflict?

Update : March 2020 Director: Professor Dr Harco Willems (KU Leuven), co-director Dr Marleen De Meyer (KU Leuven & NVIC)

As far back as 1575, Leiden University researchers have been leaving their mark on the world.

How can theories about modern disinformation help to understand how Roman documentary fictions functioned?

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

Subproject of

Between 1798 and 1813 successive regimes attempted to enforce a fundamental geographical and administrative redivision of the Netherlands. The provinces that had been sovereign states within the Republic of the United Netherlands for over two centuries were dissolved and replaced by ‘departments’, subordinate…

Leiden University has been promoting studies on Latin America and the Caribbean for a long time.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

He’s a fast and animated speaker, which is only logical because Gerard van Westen is driving an express train. His destination? A virtual human, consisting of algorithms that predict what an administered substance will do in the body. The train is already a long way down the line and the pharmaceutical…

How can legal education in Indonesia become more relevant for graduates who will work in contexts of legal pluralism, aiming for social justice and providing legal services that common citizens need?

Together Leiden University, Delft University of Technology and Erasmus University Rotterdam form the strategic alliance Leiden-Delft-Erasmus Universities.

Leids onderzoek naar bestraffing komt tot stand uit verschillende disciplines. Het onderzoeksproject kent een juridische, criminologische, sociaalwetenschappelijke en filosofische invalshoek.

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

Ending the United Kingdom’s (UK) forty-seven year European Union (EU) membership has fundamentally transformed its relationship with the EU. After years of tumultuous negotiations, international law now once again governs the UK’s relationship with the EU. This has resulted in a sophisticated body of…

On 10 November Guanmian Xu successfully defended a doctoral thesis and graduated.

The ties between Leiden University and South East Asia, especially Indonesia, have been strong for centuries.

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.

The institute hosts criminal lawyers and criminologists who engage in high-quality scientific research that is also relevant for society.

This project has two main aims: I. Determine when novelty promotes fear extinction. II. Discover the neurobiological mechanisms underlying these effects.

Improving healthcare with our scientific discoveries: that is the goal of pharmaceutical research at Leiden University. And there’s a lot involved in that. Our research starts with the discovery of the effect achieved by a particular substance, and sometimes continues all the way through to the development…

Within the Graduate School you can conduct your PhD research in a wide range of subjects across the Social and Behavioural Sciences, with five distinct research areas offered by its Institutes.

To what extent are there differences between countries in and outside the European Union and the Schengen area in the level of crimmigration, the merger between migration control and crime control, and to what extent can these differences be explained by the way in which state and non-state actors in…

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

This project is aimed at 1) elucidating the role of attention in itch and pain, including orientation, and attentional disengagement (i.e., directing attention away) from itch and pain; and 2) modifiability of these attentional processes.
