Now that the new Dutch government's plans are set out on paper, the chess game begins for cabinet formation leader Richard van Zwol. He has to make the next move and put together the ministerial team. But how do you know if you’ve made the right move with the right chess piece? And who is a suitable…

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

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).

This book analyses the emergence of modern parties in nineteenth-century Europe and explores their connection with the slowly developing institution of democracy.

The aromatic infrared bands (AIBs) seen throughout the interstellar medium (ISM) are generally thought to be carried by polycyclic aromatic hydrocarbons (PAHs) and their nitrogen analogues (PANHs).

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

How do processes of coalition-formation influence patterns of decision-making in the European Union?

The physical landscape is the setting in which human activities take place. Landscape and site context during human occupation is one of the areas of concern for the geoarchaeologist. A detailed stratigraphical study -both on- and off-site- clearly enhances the interpretation of the archaeologists,…

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

CML-IA is a database that contains characterisation factors for life cycle impact assessment (LCIA) and is easily read by the CMLCA software program.

Immersive, interdisciplinary and didactically-sound learning activities designed to promote capacity building in various game-based formats.

De formatie sleept voort en de roep om een minderheidskabinet klinkt luider. Staatsrechtgeleerde Wim Voermans, waarschuwt in een recent opiniestuk in de Volkskrant dat zo’n constructie instabiel is en de kans op een nieuwe kabinetsval vergroot.

Following the recent debate on the formation of a new Dutch government, there seems to be no clear definition of an extra parliamentary cabinet. Wim Voermans, Professor of Constitutional Law, discusses this in Dutch magazine ‘Vrij Nederland’ (VN).

Recently, a pro-Palestine demonstration was held outside the National Holocaust Museum in Amsterdam during its opening, which was being attended by President Herzog of Israel. Wilders’ response? ‘It smells like a political campaign by the far-left mayor of Amsterdam. Irresponsible.’

This subproject offers a political and transnational perspective on the development and uses of public memories of the Revolt in the seventeenth century.

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…

Abstracts can be submitted only if you are registered for the conference, including the required payment.

Covid-19 is een disruptieve ontwikkeling die hier en nu veel vraagt van zorgprofessionals, bestuurders en managers. Hoewel de crisis nog volop bezig is, is nu al duidelijk dat het Coronavirus een blijvende impact zal hebben op zorginstellingen en fundamentele vragen oproept over hoe we onze zorg optimaal…

Leiden University offers its students a wide range of bachelor's, master's and minors that explore sustainability or climate. Here, you find an overview of those programmes in the academic year 2020-2021.

Abstract submission is now closed.

How did parties as political organizations emerge?

Please note that SP2024 uses a two-step submission process with two separate deadlines; 20 December 2023 for the abstract and 12 January 2024 for the full paper. The abstract submission (or pre-submission) is needed for the program chairs to assign your submission to reviewers with matching expertise.…

Within 3 months of the start of the PhD project, your supervisors and you will draw up a Training and Supervision Plan in consultation with you and the other members of the supervision team. 

Multiple identities of elites and ‘commoners’ viewed through the lens of crafting from the Chalcolithic to the Iron Ages in Europe and the Mediterranean

Research at Leiden Observatory spans the full width of modern astrophysical enquiry. It is based on observation, theory, simulation, and experiment. Two broad clusters characterize the ongoing research. Within each theme, researchers carry out their personal and specialized research programme. The two…

On 1 September, the conference of the Kirchheiner Chair ‘Government and citizens: A matter of trust’ took place. In a packed hall in the beautiful Old Observatory of Leiden University, under the inspiring leadership of Willemien den Ouden, a debate was held on the role of the Dutch National Ombudsman,…

The Municipality of Lelystad is using a new kind of council agreement: a general agreement that all parties are entitled to have their say on. As Professor of Constitutional Law Wim Voermans recently said on Dutch current affairs programme ‘EenVandaag’, this form of agreement would also lend itself…

On April 26th, Kate Bellamy succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Kate on this great result.

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

The applications of studying the early development of insects range from agriculture to material science.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

ICEHL will take place in Leiden on 7-11 June, 2021.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.
