Martijn Bezemer has been appointed as professor in “Ecology of plant-microbe-insect interactions” within the Faculty of Science at the Institute of Biology from the 1st of September 2016. His main research focus is on aboveground-belowground interactions.

The genomic DNA of every organism is organized and compacted in order to fit inside the cell. This is achieved by the joint action of numerous architectural proteins that aid in folding the genome. Genome folding is tightly interconnected with transcription, with genes in certain regions being silenced,…

Episode 1: The Golden Horde in a Global Perspective: Imperial Strategies. This project intends to challenge the conventional way of considering the nomadic state organizations and the role of Nomads in world history.

The Middle Paleolithic site of Neumark was first discovered in the 1980’s by German geologist Matthias Thomae.

Subproject of

This PhD-thesis analyses the relationship between the parties’ choices in the CPB Netherlands Bureau for Economic Policy Analysis’ assessments of the election manifestos and coalition agreements over the period 1986-2017, and tries to explain this relationship.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

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.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

How did a circle of Soviet artists and writers virtually unknown until perestroika turn into Russia’s most influential contemporary art movement? This book reconstructs the cultural history and canonization of a group of painters and poets known as the Moscow conceptualists, who paradoxically did not…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

This is a study of Plateau Shimakonde, a sub-dialect of the Makonde language which is spoken on the Makonde Plateau in northern Mozambique.

Peyman Jafari defended his thesis on 11 October 2018

This summer school will explore the concept of socioeconomic diplomacy in the context of global empire building (16th-19th centuries).

The Astronomy and Data Science master’s specialisation at Leiden University combines advanced Astronomy courses with relevant courses from the Computer Science programme at Leiden University.

Legitimacy is generally a term that is associated with the state. The term surfaces when there are problems with state legitimacy—when it is lacking or absent. This present volume attempts to think through the relevance of the concept of legitimacy for other political actors than the state.

The Brazilian economy has long been defined by its enormous potential. Over the past 30 years, some of this has at last been realised. Latin America’s largest economy has rapidly risen in global importance while poverty at home has declined. Yet, despite periods of progress, Brazil remains prone to…

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

On the 9th of November Syahril Siddik successfully defended a doctoral thesis and graduated.

This book examines the history of The Netherlands in a way that connects global processes to local developments.

This specialisation focuses on the interplay of international rules and institutions, non-governmental organisations, and national governments in an era of emerging powers, technological change and pressing issues of security, prosperity and sustainability.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

Attitudes towards cultural heritage have long been characterised by an ‘endangerment sensibility’ concerned with preventing losses. Recently, however, critical heritage scholars have argued that loss can be generative, facilitating the formation of new values and attachments. Their arguments have focused…

Emphasizing on the key role of polysemy in forming the lexicon is the main goal to be achieved in this dissertation paper. The paper suggests a qualitative evaluation of polysemy in comparing it with other relations that form the lexicon. The research confirms that the polysemic links must not be modeled…

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

This project examines how speakers store and process regular pitch variation.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

On Thursday 20 May 2021, Tania Li delivered the annual Van Vollenhoven Lecture.

This dissertation provides a novel perspective on the interaction between quantifier scope and ellipsis. It presents a detailed investigation of the scopal interaction between English negative indefinites, modals, and quantified phrases in ellipsis. One of the crucial observations is that a negative…

Our mission is to bring together research and practice focused on the improvement of mental health and the enhancement of treatment / psychotherapy success. To reach this goal we focus on the following paths:

Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…
