Atopic eczema is a skin disease with increasing incidence currently affecting 25% of the paediatric population. In atopic eczema the skin barrier function is reduced. This barrier is formed by the outermost layer of the skin called the stratum corneum (SC). The SC consists of terminally differentiated…

The bi-annual interactive seminars of the Platform for Postcolonial Readings are all about sharing our enthusiasm about our field of research and our eagerness to learn more about its theoretical intricacies. Our seminars, although informal, adopt a well-defined format. Each meeting is organized around…

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Some species of proteins which can form liquid-like condensates, also exhibit growth into fibers (or fibrils). One particularly interesting set of such proteins are those that are associated with neurodegeneration in which the fiber growth may be related to the pathological fibrils observed in disea…

What is the origin of solar systems?

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

The FOI project has a number of topics it aims to investigate. These are: State, Economy, Culture and Papyri. You will find links to bibliographies on this page.

People in Asia increasingly feel the need for a strong identity. This is the consequence of developments such as globalisation and the realisation that Asian countries such as China and India are becoming new world powers. Professor Hilde De Weerdt studies how political ideas and national identity spread…

Politically speaking, the Frisian coastal area constitutes a special case in late medieval Europe since it was not subject to an overlord as it withstood feudalization in the 13th century. Its many sub regions, which were dominated by elites of small noblemen and freeholders, long time succeeded in…

How did galaxies form? How did galaxies evolve?

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

Why do communities form militias to defend themselves against violence during civil war? Using original interviews with former combatants and civilians and archival material from extensive fieldwork in Mozambique, Corinna Jentzsch (Leiden University Institute of Political Science) explains the timing,…

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…

By examining the impact of Islam on the daily life of those living under its rule, the goal of this project is to understand the striking newness of Islamic society and its debt to the diverse cultures it superseded. Questions will be the extent, character, and ambition of Muslim state competency at…

Aristocratic dynasties have long been regarded as fundamental to the development of early modern society and government. Yet recent work by political historians has increasingly questioned the dominant role of ruling families in state formation, underlining instead the continued importance and independence…

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

The purpose of this study was to investigate the formation and growth kinetics of complexes between proteins and oppositely charged polyelectrolytes.

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…
