Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

Key publications of the Skin Barrier and Vaccination group.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

‘Islam and Muslims are not something that happened to Europe; they are part of Europe. In fact, Islam is one the biggest constants in European history,’ argues Professor Maurits Berger in the new eight-part History of Islam in Europe podcast series of the Leiden University Faculty of Humanities.

Investigating the intercultural connections that shaped practices of knowledge production in colonial Dutch Brazil.

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

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…

Migration and crime are in the spotlight in society. Within the Institute for Criminal Law and Criminology, research in this area has strongly developed in recent years. The concept of Crimmigration is central to this.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

Effective host defence against tuberculosis bacteria depends on a properly balanced level of inflammation. The Inflammafish project uses zebrafish larvae to study how autophagy controls this inflammation and vice versa.

The project examines the political conflict in the Red River Valley of Louisiana between the majority-black Republican Party and the overwhelmingly white Democratic Party by studying the composition and actions of each party.

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Netherton Syndrome (NTS) is a rare genetic skin disease caused by mutations in the serine protease inhibitor Kazal-type 5 gene, which encodes the lympho-epithelial Kazal-type-related inhibitor. NTS patients have a profound impaired skin barrier function. Because SC lipids play a crucial role in the…

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

On 16 June 2020, Andrea Varga defended her thesis 'Establishing State Responsibility in the Absence of Effective Government'. The doctoral research was supervised by Prof. N.J. Schrijver and Prof. F. Baetens (University of Oslo).

Yi-Wen Cheng defended her thesis on 28 May 2015

This article provides a comprehensive analysis of the Islamic State's use of images taken by drones, drawing on a dataset of ISIS propaganda images from October 2016 to December 2018.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

This study seeks to identify suitable local environments conditions for the objects displayed at the Jordanian museums using the proper methods in order to contribute to the stabilization of these objects.

Here we share findings into the effectiveness of the Designing Your Life education at Leiden University. Our study indicates that DYL education has a positive effect on students’ confidence and competencies.

In order to optimize treatment, it is necessary to closely monitor and manage the patient’s health status by means of ‘precision diagnostics, personalized prognosis and targeted therapy’. The specialisation combines the techniques and applications of these sensing (monitoring) and stimulation techniques.…

The IBL-office welcomes you and will answer all your questions regarding general information, administrative issues, or redirections towards IBL subdivisions and people.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

Increasingly, crime and immigration are mentioned in one breath. This 'interweaving' of these terms is referred to as crimmigration, an expression mainly used in legal science. But what does crimmigration actually entail in practice? Defence on 8 January 2020.

Finding solutions to the Israeli-Palestinian conflict is the not-inconsiderable task of the new Peace Academy in The Hague. Professor Maurits Berger and twelve students from different conflict zones are starting a creative thinking process that aims to discover the basic conditions for peace in the…

Questionnaires or concentration tasks can be used to screen for anxiety, but so too can EEG recordings – at least indirectly. The frequent mind wandering of anxious people can also be seen on MRI scans. These are just some of the findings of clinical neuropsychologist Dana van Son. PhD defence on 24…

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

Nearly eight decades after the liberation of Auschwitz, we continue to learn more about how the Holocaust “happened” in central and eastern Europe. In Prof. dr. Sarah Cramsey’s History MA Research Seminar “New Approaches to the Holocaust in Central and Eastern Europe,” a dozen Leiden students read what…

Political scientist Nicolas Blarel (Leiden University) analsyses how non-state actors can (directly or directly) attempt to provoke conditions for a crisis between state actors that have nuclear capabilities. He argues that there is an urgent but complicated and understudied task to understand and manage…
