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

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.

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

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

How can the legal and socio-legal research skills of Indonesian jurists be increased in order to promote legal certainty and to strengthen the capacity of the judicial training in the country?

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…

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…

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.

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…

Planets are formed in disks of gas and dust around young stars.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

On Wednesday 14 February 2024 Yorum Beekman successfully defended a doctoral thesis and graduated.

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…

On 25 January 2024 H.J. Pak successfully defended a doctoral thesis and graduated.

Celebrating 20 years of Environmental Research and Education in Northern Cameroon

On Thursday 30 May 2024 Corrie van Maris successfully defended a doctoral thesis and graduated.

Physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been done so well with actual atoms. It is an important step towards light-based quantum technology. Publication on August 30th in Nature Communications.

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

Research using the ALMA telescope by scientists including Leiden's John Tobin and Steven Bos has produced the first images of the water snow line within a protoplanetary disc. Publication in Nature on 14 July.

In the discs of dust and gasses around young stars, mysterious structures occur. Together with professor Ewine van Dishoeck, PhD student Paolo Cazzoletti investigate how we can explain these forms, such as rings, spirals and holes. On 12 December, he will defend his thesis.

On Tuesday 11 June 2024 Olivia Ramble successfully defended a doctoral thesis and graduated.

On Tuesday 3 September 2024 Straton Papagianneas successfully defended a doctoral thesis and graduated.
