In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…

On Thursday 28 January 2016, Prof. Carsten Stahn contributed to the OPCW Sub-Working Group on Non-State Actors, together with Professors Andrew Clapham (Geneva) and Dapo Akande (Oxford), in the presence of the Ahmet Üzümcü, Director-General of the OPCW.

This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

Foundation for Industry (FIND) brings together 5 universities with 10 labs, 11 Dutch companies, ranging from start-ups to multinationals, and 2 knowledge institutes to pave the way for a new wave of AI-based automation that helps the Dutch industry strengthen and keep its international competitive advantage…

From the first semester of 2026, Leiden University and Universidad Diego Portales (Santiago, Chile) will launch three online virtual exchange programmes. The themes are: political analysis, tensions surrounding Indigenous peoples in Latin America, and the securitisation of borders.

These are the staff members of the Leiden - Latin America and the Caribbean Centre

The Leiden astronomer Huib van Langevelde) has been selected as the new director of the Event Horizon Telescope (EHT). The EHT is a collaboration involving about 350 scientists from 18 countries. It combines the ALMA array in Chile with sub-millimeter telescopes around the world and published the first…

ChEMBL is a large-scale drug discovery database containing bioactivity information primarily extracted from scientific literature.

Tackling human trafficking has been a priority on international, national and local policy agendas for some decades now. Yet a number of knowledge gaps stand in the way of how the issue is approached. Interdisciplinary research is essential if we want to expand our knowledge to benefit policy and pr…

Fieldwork is a crucial part of the learning process for students in the Faculty of Archaeology. This includes both fieldwork aimed at collecting archaeological data and materials as well as fieldwork for heritage studies. The Faculty has established a specific centre of expertise to further shape these…

The Old Observatory has a rich history. On this page you will find a short version of the history that took place in the observatory.

The recently published book 'Tense-Switching in Classical Greek A Cognitive Approach' by Arjan Nijk provides classicists and linguists in general with a complete account of the 'historical present' in Classical Greek.

This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

In Women and Property Rights in Indonesian Islamic Contexts, eight scholars of Indonesian Islam examine women’s access to property in law courts and in village settings.

The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

Recent study led at the Leiden Observatory has observed Orion with unprecedented detail. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot…

A team of European astronomers under Leiden leadership has discovered that dust particles around a star already coagulate before the star is fully grown. These agglomerated dust particles are the first step in the formation of planets. The research publish their discovery in the journal of Nature As…

This project aims to study the Aesopian fable from 1500 to the present day in its complex relationship between text, illustration and education, adopting a broad, transnational perspective.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

This research cluster aims to analyse and interpret the formation and transmission of Graeco-Roman culture by exploring the relationships between cultural products (texts, objects, practices) and their societal and historical contexts.

These are our lecturers (in alphabetical order) for the 2025 Summer School in Languages and Linguistics.

How is law shaped by and shaping social, political and economic change in Indonesia?

Through a lens that examines the intersection of ageing, gender, class, and migration, this project addresses the “care deficit” in European countries and the employment of migrant women from Latin America to fill this deficit.

This research examines how punishment and deterrence is articulated and expressed in the management of migration in Mexico.

This paper addresses the gap that explores how agencies might allocate their personnel so as to maximise performance with the personnel they have.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

HomininSpace is an agent based modelling and simulation system in which fluctuating carrying capacity is the key attractor for hominin dispersal. A parameterized and spatially explicit reconstructed palaeo-environment models available energy in the form of secondary biomass using reconstructed climate…

In the Criminal Justice research programme, (criminal) law researchers and social scientists – many of whom are criminologists – collaborate on various projects. The research programme focuses on the content and form of decisions that could be, should be and are taken in by actors in the criminal justice…
