Ahead of the times? We’ve been that for 450 years. As the oldest university in the Netherlands, we’ve sailed through the centuries with our sights fixed firmly on the society of the future. Our anniversary in 2025 is a chance to look back too. A chance to celebrate the impact of our research and teaching.…

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

This project, executed by Marieke Hendriksen MA MRes, aims at an analysis of how the early modern anatomical collections of Leiden University were rooted in ideals of perfection in different fields of knowledge and expertise.

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

Pupils and students learn best if they are actively doing something with the material. Professor Wilfried Admiraal is studying the best teaching methods and assignments to achieve this.

Here I propose to study the relationship between autonomic pupil-synchronisation and trust, at the behavioural and neural level, and examine a targeted set of possible contextual moderators.

The discovery of new medicines is a tedious and lengthy process. On average, over 10,000 molecules need to be studied for one to become a drug and reach the patient. Part of that process are the very costly clinical trials in humans, and candidate drugs often fail due to side effects or lack of efficacy.…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

The thesis introduces three methods for high-dimensional prediction problems in the biomedical field. The methods make use of empirical and variational Bayes in the estimation.

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

The Passion in Profession series features researchers who are specialised in Islamic, Middle Eastern and Central Asian studies. With the series, LUCIS aims to show what inspires them in their work by highlighting an object or concept that they feel passionate about.

Knowledge and culture subproject 2:

When to launch a next-generation product in a competitive market and how much capacity should be allocated to it

Spontaneously helping one another, why do we bother? It is believed that lending a hand to others promotes social bonding, helping us to connect with each other and even build friendships. In our experiment, in which the adult researcher ‘accidentally’ dropped matches on the floor, most adolescents…

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

This one-year, English-taught Master's programme offers insights on general developments as well as the specific challenges in the field of the governance of crisis and security, with in-depth knowledge of sub-fields of crisis and security management.

The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

BACKGROUND: Explant human skin equivalents (Ex-HSEs) can be generated by placing a 4mm skin biopsy onto a dermal equivalent. The keratinocytes migrate from the biopsy onto the dermal equivalent, differentiate and form the epidermis of 1(st) generation Ex-HSEs. This is especially suitable for the expansion…

A hot topic in educational sciences is whether and how reading medium (paper vs. screen) affects reading comprehension. Especially in the media – but also in schools – their appears to be a preference for texts presented on paper: Paper texts are thought to induce a more intensive reading strategy,…

Can a virtual character’s friendly non-verbal responses stimulate eye-contact in individuals with varying levels of social anxiety?

eLaw is Proud to announce that our colleague Dr Constanta Rosca successfully defended her PhD thesis 'Digital Arms for Digital Consumer Harms: Mapping Legal and Technical Solutions for Dark Patterns in EU Consumer Law' on Monday 2 December 2024 at her alma mater, Maastricht University Faculty of Law…

Highlights the extent to which the two thinkers share a common philosophical framework, while also demonstrating how Levinas shifts the orientation of philosophical thinking from truth to justice.

References to nature and the environment in the Caribbean literary and the contemporary age of globalization.

This study focuses on increasing our understanding of the different pathways converts take during conversion to Islam.

The aim of this work was to study the applicability of antigen-coated pH-sensitive microneedle arrays for effective vaccination strategies. Therefore, a model antigen (ovalbumin) was coated onto pH-sensitive (pyridine-modified) microneedle arrays to test pH-triggered antigen release by applying the…

Osteoarchaeologists help forensic scientists solve crimes. They also study bone material from the Second World War in order to identify victims.

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

In science, it is of vital importance that multiple studies corroborate the same result. Researchers therefore need to know all the details of previous experiments in order to implement the procedures as exactly as possible. However, this is becoming a major problem in neuroscience, as animal studies…

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

A study by a Leiden-Wageningen group shows that present-day humans are biologically poorly equipped to deal with the toxins they are regularly exposed to in smoky environments: compared to earlier hominins, we modern humans are probably even worse off. The study appeared in Molecular Biology and Evolution.…

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

The Leiden | Islam interview series contains short documentary-style videos including interview flashes with leading scholars in the field of Islam and Muslim societies. With this series, LUCIS aims to show the value of unconventional insights related to Islam and Muslim societies, and to relate them…

On the 24th of October, Nurenzia Yannuar successfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Nurenzia on this achievement.

How can we broaden youth participation in STEM Learning

In this dissertation a large corpus of letter signs and texts gathered during fieldwork in Niger, and to a lesser extent Mali and Burkina Faso is used to show the graphemic diversity of the traditional script of the Tuaregs, tifinagh, and to analyze the orthographic system.

Leiden University has signed a substantial number of Memoranda of Understanding with institutions in Latin America and the Caribbean Region.

On a referendum held on May 21, 2006, 55.5% of voters in Montenegro voted in favor of their country’s independence. While in numerical terms the outcome shows overwhelming support for independent Montenegro, from a normative standpoint it was a narrow win. The normative framework that regulated rules…

A monumental and extraordinary Early Iron Age Hallstatt C barrow from the ritual landscape of Oss-Zevenbergen

Do babies and toddlers thrive more in a noisy or quiet day care centre? Research by specialist in Education and Child Studies Claudia Werner shows that children feel most comfortable in an environment where there is a little noise. With this kind of research, the method of analysis is very important.…

The project investigates epistemicity: how the knowledge of the speaker and hearer can be expressed in the grammar. This shows us how speakers organise their knowledge, and whether this is influenced by the language they speak.
