1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

The research programme Probability Theory focuses on probability theory and on operations research.

Globalisation leads to more contradictions between national and international tax norms. It therefore seems necessary to revise the fiscal legislation. This is not only due to the problem posed by multinationals, but also to changing norms regarding tax burden distribution. Fundamental research on the…

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).

This project aims to integrate three of the largest survey databases in the Mediterranean to study the impact of the megalopolis Rome on its direct hinterland.

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

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Several single-stranded RNA viruses make use of Xrn1-resistant RNAs in their 3’ untranslated regions of their genome RNAs in order to increase their pathogenicity.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Here we explain how to attend the workshop "How to Get a PhD Position" on May 7 2021.

A Diachronic Perspective on the Aegean

On the 25th of September, Yufang Wang successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Yufang on this achievement!

In the MSc Chemistry programme you will focus your studies on one of LIC's two main research areas, Chemistry for Health or Chemistry for Sustainability, and one specialisation.

This thesis focuses on enhancing predictions of central nervous system drug exposure using the LeiCNS-PK3.0, a physiologically based pharmacokinetic model.

Identifying and explaining change in the structure of central state bureaucracies and the determinants of survival of individual public organizations are two closely related areas of research in public administration. We aim to bridge the gap between these two main strands of studies of organizational…

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

Smart digital infrastructures predicated on myriads of sensors distributed in the environment are often rendered as key to contemporary urban security governance to detect risky or suspicious entities before or during a criminal event takes place. At the same time, they often involve surveillance of…

On February 7th, Lotte Dros-Hendriks succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Lotte on this great result.

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.

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

Current status and future prospects

The availability of indicators based on social media has opened the possibility to track the online interactions between social media users and scholarly entities.

The ERC project 'Food citizens?' is a comparative analysis of a growing phenomenon in Europe: collective food procurement, namely networks of people who organize direct food production, distribution, and consumption.

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.

Living labs make it possible for citizens to participate in research for sustainable development of their environment. This way citizens, together with scientists and stakeholders, create local conditions for food production, healthy environment, and biodiversity.
