This thesis investigates how quantum, quantum-inspired, and hybrid quantum-classical computation can enhance key points of the automated machine learning (AutoML) pipeline under the constraints of noisy intermediate-scale quantum (NISQ) devices.

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

Leiden Professor of Astronomy Mike Garrett is searching for signs of extraterrestrial intelligence. In his Kaiser lecture on 23 April he will discuss how far science has progressed in this quest.

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?

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.

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

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.

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…

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…

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?

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?

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,…

Education and Organisation Development

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

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…

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.

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

We study the dynamics of individual emitters in micro cavities.

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

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

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…

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.

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…

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.

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…

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…

Since 2009, at ACPA, 91 candidates received their PhD in Creative and Performing Arts. On this page you will find an overview of ACPA's alumni.

The Leiden Institute of Physics has been awarded three out of twelve available grants from the FOM Projectruimte. Principal Investigators Milan Allan, Stefan Semrau and Carlo Beenakker all receive around 400,000 euro for their research.
