We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

This project investigates properties of quantity expressions across languages from the perspective of how quantity is represented in the human brain.

On the 4th of November, Aliza successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Aliza on this achievement!

The aim of this thesis was to develop aluminium salt-based nanoparticles that may ultimately be used as adjuvant in human vaccines.

Within the Leiden Law School, the section notarial law teaches in a number of courses in the bachelor program as well as in all courses in the master program notarial law.

On 25 November 2018, Laurens de Hoog defended his thesis 'De prioriteitsregel in het vermogensrecht'. The doctoral research was supervised by Prof. mr. W.G. Huijgen.

We investigate emergent structures and dynamics of soft materials self-assembled from microscopic constituents.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

This programme starts from the idea that cultural discourse is one of the main engines of intellectual history and the history of ideas.

The thesis deals with the study of giant radio galaxies (GRGs), which are radio galaxies of megaparsec sizes.

On 28 June, Willem Ruijs defended the thesis 'Pawnbroking'. The doctoral research was supervised by r Pim Rank and Willem van Boom.

Hot rocky exoplanets are planets that orbit so close to their host star that they possess a molten surface.

This book explores the intellectual history of the Dutch empire from the sixteenth century to the postcolonial era, going beyond systemic thinkers to understand how empire was perceived in day-to-day life. It takes a transnational and transimperial approach to the Dutch empire, connecting European,…

The group is involved in training in areas of diagnostic skills, treatment/prevention/intervention, neuropsychological assessment, behavioral observations, clinical interviewing, knowledge of intellectual disability, autism, ADHD, psychosis and aggression.

On 18 December 2019, Mikhail Antonov defended his thesis 'Formalism, Realism and Conservatism in Russian Law'. The doctoral research was supervised by Prof. W.B. Simons.

On Wednesday 21 May Adrian Perkasa successfully defended a doctoral thesis and graduated.

On Wednesday 14 May 2025 Remzi Çakırlar successfully defended a doctoral thesis and graduated.

As Board Secretary, Corry Donner aims to be a ‘spider in the web’; someone who keeps a watchful eye on and brings together all the different perspectives of the institute’s board. Now she's left her carefully woven web at the university and transfer her tasks to her successor. Last September, we talked…

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…

The master’s specialisation Research in Physics, Quantum Matter and Optics at Leiden University offers a thorough experience on the front line of physics research with a practical training of communicative and computer skills. The programme focuses on Condensed Matter problems, such as Molecular Electronics,…

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

The polypept(o)ide hybrid material attracted more and more attention over the past decade by combining the multifunctional characteristics of polypeptides with the shielding characteristics of polypeptoid-pSar possessing similar properties as a shielding material as polvethylene glycol(PEG). Polysarcosine…

This project aims at investigating the syntactic role of focus in ellipsis across languages.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

Promotores: Prof.dr. W.J.G.M. Peijnenburg & Dr. M.G. Vijver

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

The main theme of this thesis is the theoretical study of Gaussian processes as a tool in Bayesian nonparametric statistics.

Lack of manliness, avaricious or too imaginative. These are just a few of the accusations with which British scientists discredited each other over a hundred years ago. PhD candidate Léjon Saarloos researched British scientists around the year 1900 and their idea of what makes a good - and therefore…

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

Knowledge on how to adjust a drug dose in special patient populations such as (prematurely born) neonates or children, obese individuals or critically-ill patients, is not only crucial for novel compounds, but also for existing drugs which are often used in an off-label manner in these special patient…
