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…

Therapeutic proteins have revolutionized the treatment of many severe diseases like multiple sclerosis, haemophilia, diabetes and many more. Unfortunately, even recombinant proteins with structures (almost) identical to those of their endogenous counterparts often induce the formation of anti drug antibodies…

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. 

This edited volume suggests promising new avenues of research in analyzing coalition politics. Written by a group of leading scholars, the book clarifies a number of concepts too often taken for granted in the existing literature, performs theoretically-driven and methodologically novel comparative…

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

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.

Leiden University has a strong tradition in language teaching, in various settings: for instance in the BA and MA language and culture programmes, area studies programmes, international studies, minors and electives. Currently, 20 different languages are taught throughout different institutes and pr…

ERC Starting Grant: The Van Manen Project. This five year project (2023-2028) is made possible with an ERC Starting Grant. It aims to (digitally) reunite all parts of the Van Manen Collection. This enables us to study it as a whole, helping us to understand the process of collection formation. More…

In this study, the formation of the Tocharian subjunctive is described, its use and meaning are analysed and its origins are investigated.

What is the cost of visual complexity? This dissertation sets out to determine the effect of the complexity of word formation on the legibility of Arabic and the role that vocalization plays in reading.

PNAS publication on protein encounter complexes

This study offers a new approach to the history of sites, archaeology, and heritage formation in Asia, at both the local and the trans-regional levels.

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…

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

Cardiovascular disease is the leading cause of death worldwide.

Ideology and Christianity in Japan shows the major role played by Christian-related discourse in the formation of early-modern and modern Japanese political ideology.

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…

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

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…

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

Edith Schippers, Minister of Health, will be investing six million euros over the coming four years to boost research on new antibiotics. The programme will be set up by several different parties, including the Leiden Centre for Antimicrobial Research.

On 23 September, the Leiden alderman for the Management of Public Space was presented with a Ginkgo Biloba in the Blekerspark.
