Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

The analysis of protein residues extracted from the storage containers of circa 50,000 year old bone-tools reveals Neandertal strategic selection of bovid ribs to make some of their “lissoirs”.

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

Imagining Urban Complexity introduces passionate and critical perspectives on the link between the humanities and urban studies.

On the 6th of July, Anthony Jakob successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Anthony on this achievement!

Taking as a point of departure the Italian American community in Boston and its process of collective remembrance surrounding Saint Anthony’s Feast, we address the limits and potential of montage.

Priya Swamy defended her thesis on 27 October 2016

The Patriot behind the pot tells the story of pottery, people and politics in the Netherlands during a time of great revolutions -revolutions both in a political and industrial sense.

The advanced insights obtained for the CNS PBPK model development are currently used to develop advanced mathematical models for drug distribution prediction in other body tissues protected by barriers, such as the gut. The gut PBPK model will be linked to drug effects for treatment of colon cancer.

Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

The Graduate School of Science offers PhD programmes spanning the entire spectrum of science from Mathematics to Environmental Science.

My current research focuses on criminality and gender interactions in nineteenth-century Europe. This project uses a comparative methodology to explain gender constructions in a criminal and in a court setting.

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

The project Going Dutch investigates why the link between being or becoming Dutch, and knowledge of Standard Dutch is so often taken for granted in public discourse, by diving into its historical roots.

From 2012 onwards the primary scholarly and media focus in regard to foreign fighters has been on the large number of Westerners joining jihadist groups in Syria and Iraq. Yet, much less attention has been paid to another conflict in the ring around Europe that attracted foreign fighters: the Russo-Ukrainian…

Live from the ASMS Conference 2015 in Saint Louis: Baljit Ubhi, our Metabolomics Specialist, has a coffee with Rawi Ramautar, Assistant Professor at the Leiden Academic Center for Drug Research.

The Ada Lovelace Distinguished Lecture Series brings outstanding computer scientists from around the world to Leiden University. The lecturers will share exciting ideas and results from the forefront of computer science.

In 1989 the Board of Governors and the Council of Leiden University granted the establishment of a special Chair for Central European Studies with a focus on Austria: 'Lehrstuhl für mitteleuropäische Studien mit besonderer Berücksichtigung Österreichs'.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

The handbook is a wide-ranging survey of a crucial period in prehistory during which many social, economic, and technological changes took place. Written by specialists in the field, the book provides coverage both of the themes that characterise the period, and of the specific developments that took…

Providing a valuable overview of regionalism throughout the entire continent, Regionalism in Modern Europe combines both geographical and thematic approaches to examine the origins and development of regional movements and identities in Europe from 1890 to the present.

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

In June-August 2010 large scale excavations were executed on the cemetery belonging to the monastery, an area now termed the Paardenmarkt, by Hollandia Archeologen in cooperation with Leiden University. During the course of nine weeks, the students from the former minor Human Osteoarchaeology excavated…

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).
