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…

The Leiden University Institute for Area Studies (LIAS) is devoted to the study of places in the human world from antiquity to the present time in a comparative and interdisciplinary perspective.

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

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 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…

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…

The Institute for Advanced Study has appointed astronomer and chemist Ewine Fleur van Dishoeck to its Board of Trustees, effective 5 May, 2018.

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…

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

An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings. The phenomenon around the star SU Aur may explain why so many exoplanets are not neatly aligned with their star. The European…

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…

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 this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

An environmental and palaeo-economic reconstruction.

On 20 March 2019, Tim Dekkers defended his thesis 'Mobility, Control and Technology in Border Areas: Discretion and Decision-making in the Information Age'. The doctoral research was supervised by Prof. dr. J.P. van der Leun en Prof. dr. M.A.H. van der Woude.

The Royal Netherlands Academy of Sciences (KNAW) has awarded an Academy Professorship to Ewine van Dishoeck, Professor of Molecular Astrophysics at Leiden University.

A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic mess. The researchers used the Atacama Large Millimeter/submillimeter…

Astronomy departments at Dutch universities is among the top of the world rankings for astronomical institutions. This is the conclusion drawn from a recent evaluation of the Netherlands Research School for Astronomy (NOVA) and the astronomy institutions of the University of Amsterdam, the University…

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…

Geology and Paleobotany of the Area surrounding the Archaeological Excavation at the Hazendonk River Dune (Western Netherlands).

To what extent are, can, and should, human trafficking and human smuggling be(ing) seen as interlinked phenomena? What are the consequences of seeing the phenomena as either distinct or interlinked for the way in which migrants crossing intra-Schengen borders are treated.

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.
