Hunter-gatherers acquire their food through complex gender-specific foraging techniques for a relatively stable and diverse supply of energy. New research indicates that this specialisation by boys and girls starts at a very young age. Most likely, this enabled the human species to evolve much larger…

Physicists Carlo Beenakker and Jan Aarts have been elected Fellows of the American Physical Society. Carlo Beenakker: 'People acknowledge your contribution, that is just very good to hear.'

Public sector decision-makers operate amidst an abundance of information and unclear political objectives. Attention is the sine qua non of policy-making: What is attended to can be addressed in policy responses; what is overlooked or goes unnoticed cannot. Despite its importance, public administration…

How De Haan is using language in general and his specific style of language in particular to provide truth, solidarity and justice for both the individual and the collective?

Multi-objective evolutionary computation aims to find high quality (Pareto optimal) solutions that represent the trade-off between multiple objectives.

The Master’s in Health, Ageing and Society gives you the insight, knowledge and skills to change care for older people. This change is needed in order to guarantee care for senior citizens in the future, but also offers solutions for growing old more happily and with more vitality.

The plans for making the University Library (UB) more sustainable will be carried out in three steps: first the glazing at the front of the building will be replaced with HR++ glass, then the skylights will be renewed and finally the air conditioning system will be updated. Once these steps have been…

Het stagebureau is er voor algemene informatie over de stage en advies tijdens het zoeken naar een stage. Ook als u een stageplaats heeft, kunt u terecht bij het stagebureau van Pedagogische Wetenschappen.

We are a diverse collective with members from different faculties and organisations. Select a faculty or organisation in the left column to search and connect with members. Have questions or want to become a member? Get in touch with the steering committee.

Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

How can the Safe and Sustainable by Design (SSbD) framework developed in the SSbD4CheM project facilitate the creation of safer and more sustainable chemicals and materials across various industries?

Top scientists of three Dutch universities are working on software and systems for quantum computers. Researchers of the Leiden Institute of Advanced Computer Science (LIACS) and the Leiden Institute of Physics (LION) are developing new algorithms to make those super computers work. The coming years,…

Of the 111 Spinoza Prizes that have been awarded since 1995, 28 have gone to researchers from Leiden University.

Education and Organisation Development

How can an effective ‘Safe and Circular by Design’ method be developed for practical application in a designer’s context, particularly for the initial stages of product design, incorporating Safe-by-design strategies, LCA/LCT, risk assessment and ethics?

Imagine how much time, money and discomfort it would save: a personalised treatment for each individual patient. Precision medicine like this is coming ever closer, thanks in part to Elise Dusseldorp’s algorithms. They retrieve a wealth of information from research data.

The following page offers tips for more sustainable travel options, such as taking the train or bus, and highlights online tools that can help you plan eco-friendly trips and find affordable tickets.

A full overview of MCBIM PhD theses.

The programme incorporates active engagement with the professional field through site visits, professional skills trainings, moot court and an internship.

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

We study the dynamics of individual emitters in micro cavities.

The leading argument of this doctoral thesis is that Aristotle’s text De Interpretatione is of methodical relevance for present-day philosophical thinking. In the era of science and technology, the status of philosophy has become problematic.

Leiden University actively seeks to prepare students for the labour market and wants to help young alumni at the start of their careers. For this we like to use the knowledge and experience of Leiden alumni. To bring these students and young alumni who have questions about their career in contact with…

This interdisciplinary project applies data science techniques to qualitatively and quantitatively visualize the interaction between the University and the city of Leiden (Town&Gown) from 1575 onwards. One of the possible angles for follow-up research is diversity, especially from the international…

This longitudinal study is focused on neurodevelopmental problems in young children with XXY, XXX and XYY, aged 1 to 6 years.

In order to choose your master, it is important to do some soul searching. If you know who you are, what you want, and what you find important in life, you will be better able to assess what suits you and what can help you to come to the right decision.

When applying for exchange or study abroad at Leiden University, you will select the individual courses you want to follow and so create your own personal study programme.

In an age before GoogleDocs and LinkedIn, 19th-century scholars relied on letter-writing for collaboration, peer-feedback and the building and sustaining of academic networks. Letters were a quick, efficient way to share insights, data and discoveries. Scholarly correspondence thus allows a vital behind-the-scenes…

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

This weeks marks the 10th anniversary of the European Research Council. For the past decade, the council has contributed to many scientific projects all over Europe, including Leiden University. It has funded almost 7,000 researchers, leading to just short of 100,000 scientific articles. A total of…

Since 2009, at ACPA, 95 candidates received their PhD in Creative and Performing Arts. On this page you will find an overview of ACPA's alumni.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food.
