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…

The specialisation Bio-Pharmaceutical Sciences and Industrial Pharmacy consists of 60 EC in Bio-Pharmaceutical Sciences and 60 EC in Industrial Pharmacy.

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…

How is structural and functional brain development related to behavioral change in cognitive-control, impulse regulation, and socio-emotional functioning?

Promotors: W. Jiskoot; G.J. Witkamp, Co-promotor: M.R. Nejadnik

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…

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.

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…

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.…

We study how communication can heal and harm when patients are confronted with an illness. Most of our studies focus on serious illnesses such as advanced cancer. Communication lies at the heart of medicine, yet we do not always know which specific communication helps patients. Moreover, many complaints…

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…

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.

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…

The following editorial comments were recently published in the Common Market Law Review.

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.

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

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).

Het Empower your PhD-project wil bereiken dat Leidse promovendi meer zelfregie krijgen over hun persoonlijke en loopbaanontwikkeling.

The goal of the MODOMA-project is to create a computer model of language acquisition.

In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.

Eduard Fosch-Villaronga, Associate Professor at eLaw, contributed to 'Cyber–Physical–Human Systems', a book exploring the latest developments in interactions between cyber–physical systems and humans.

Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

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.

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.

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.…
