Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

Built Environment and Domestic Material Culture in the Medieval and Post-Medieval Cyclades, Greece (13th – 20th Centuries AD)

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

This book investigates the effects of brain lesions in the left hemisphere, specifically Broca's area, on the production and perception of vowels, of word tones and of the linguistic use of sentence melody.

Operators in the Lexicon opens with an old chestnut: why are there no natural single word lexicalizations for negations of the propositional operator and and the predicate calculus operator all: why neither *nand nor *nall?

Innovating objects in a Eurasian center of the Late Hellenistic period.

In 2021, the National Cyber Security Centre (NCSC) asked Leiden University to conduct a rapid review of best practices and possibilities for follow-up research on the integration of behavioral sciences in security by design methodologies and projects. This academic field is called security by behavioral…

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Mavlyuda Yusupova will be Central Asia Visiting Professor in November 2018. She will deliver two guest lectures for Leiden MA and PhD students.

The coastal site of Butrint is situated on a peninsula in south-western Albania, opposite the island of Corfu and Apulia in southern Italy (across the Adriatic Sea). In Medieval times, Butrint served as a connecting bridge between East and West – between Byzantium and the Latin world.

Overview of Leiden publications on Central Asia. For additional publications dedicated to a single country, please go to individual pages of the researchers, which you can access through the Researchers page.

Whereas when we started the first Project the chief aim was pure research, to find out more about the past in a region, now we see that the countries of Europe are faced with the great problem that there are far too many archaeological sites for them to deal with by excavation, but yet some kind of…

Rural cult places were of central importance in the non-urbanised areas of ancient Samnium, in central southern Italy. Their development, roles and functions in ancient society, however, remain important research questions. New excavations at one of these sanctuaries, the rural temple of S. Giovanni…

What follows is a survey of existing programs and current projects for each of the participating universities.

Diplomatica: A Journal of Diplomacy and Society addresses the broad range of work being done across the social sciences and the humanities that takes diplomacy as its focus of investigation.

Proceedings of the International Colloquium Leiden, May 29 and 30, 2008

A Selection of the Poems of Sir Constantijn Huygens (1596-1687) was published in July 2015, edited and translated by Adriaan van der Weel and Peter Davidson.

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.

In order to gain insight into the structure and function of the molecular complexes involved in chemotaxis, we use electron cryotomography (ECT). This technique allows us to directly study microbes in their native state at resolutions capable of visualizing individual proteins.

The purpose of the initiative is to establish Central Asian Studies at Leiden University. Central Asia is a region with fluid borders stretching into present-day Afghanistan, Russia, China, Mongolia, Iran and the Caucasus; a premodern highway of global interaction and today increasingly important as…

Are UN sanctions regimes in need of further formalization in terms of substantive design, procedural architecture and with a view to regulating and governing the interplay with other regimes?

As well as being a vibrant student city, with numerous housing possibilities and sports clubs, and one of the greenest cities in Europe, The Hague also hosts several important international organisations. It is the ideal place to start your future career.

This computational approach to the complexity of text comprehension is useful for describing the cognitive processes involved.

The MSc specialisation ICT in the Public Sector gives you the opportunity to study the field of IT management in a governmentall setting. You will learn how to benefit from your technical Computer Science knowledge on an administrative, management level.

Bronze Age settlement sites in the Dutch river area (c. 2000-800 BC)

This project aims to identify, quantify and map the exposure of Dutch national monuments to four climate change effects: flooding, waterlogging, drought and heat.

Researchers within the cluster are committed to the close and expert analysis of the materiality and content of the arts, literature and media they study. Different types of media bring various aspects of this core interest to the fore.

Would you like to check out a different programme while following your own? Or perhaps you’d like to delve deeper into a field of expertise? A minor is an excellent way of adding your own flavour to your study.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…
