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,…

The Leiden Political Economy Group (L-PEG) is a multi-disciplinary network of scholars with a research interest in (comparative / global) political economy based at Leiden University. Our members belong to various institutes and faculties across Leiden University, and from other universities across…

The project aims to distribute the teaching effort in a transparent way and to organise the programmes so that the best possible teaching can be provided in an efficient manner,…

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.

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.

Statistical distributions in LCA and converting between different representations of these distributions.

The SPS Monitor measures your sensory stimulus sensitivity. Sensory stimulus sensitivity refers to one's sensitivity to subtle environmental stimuli, the depth and intensity with which these stimuli are processed and the impact this has on one's functioning.

Towards self-regulated learning of speaking skills in foreign languages in secondary schools: an adaptive and practical approach.

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.

How do Chinese language teachers negotiate who they are as teachers when they work abroad? This dissertation offers clear, practice-oriented answers. It examines teacher identity - the everyday answer to 'What kind of teacher am I here?' - as it is reshaped through classroom interactions, institutional…

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…

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.

PNAS publication on protein encounter complexes

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

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

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.

Cardiovascular disease is the leading cause of death worldwide.

On Friday 15 November 2024 Chunli Song successfully defended a doctoral thesis and graduated.

Exploring Late Bronze Age attitudes towards martiality through experimentation and micro-wear analysis

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Mr. Sujadi defended his thesis on 29 June 2017

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…
