What does our faculty stand for and what will we do in the next five years? We are proud to present our new strategic plan that we made together. On this website you will find more information about what our Faculty stands for and what our course is for the coming years

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

Microbial Sciences' contribution to the Bioactive Molecules research theme is to discover new bioactive molecules and enzymes and unravel their mechanisms of action, regulatory networks, and the (bio)synthetic pathways required for their production.

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding mono- and multidisciplinary teaching.

This dissertation reports on the pedagogical content knowledge (PCK) of science teachers during a professional development program. This research intended to help us understand why and how teachers make their classroom decisions as they teach science.

SAILS aims to forge links between the different disciplines at the University and to initiate new academic partnerships.

The master’s specialisation Bio-Pharmaceutical Sciences and Industrial Pharmacy at Leiden University examines safety and quality control in the production of medicinal products, and prepares students for a career in Quality Assurance and Quality Control in the biotechnological and pharmaceutical ind…

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

Plant Sciences' contribution to the Host-Microbe Interactions research theme is to dissect how microorganisms and microbiomes interact with the plant host and the insects on those plants, and how these insights may be harnessed to improve plant growth and health, by steering microbiome composition and…

Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

The master’s specialisation Bio-Pharmaceutical Sciences and Business Studies at Leiden University combines fundamental and applied research with different aspects of business studies.

This book explores how physicists, astronomers, chemists, and historians in the late nineteenth and early twentieth centuries employed ‘epistemic virtues’ such as accuracy, objectivity, and intellectual courage. In doing so, it takes the first step in providing an integrated history of the sciences…

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

Patterned detectors are an existing technology that can be found in almost all color cameras.

This UNESCO Chair at CWTS aims to contribute to UNESCO’s agenda to foster diversity and inclusion in science. The chair has two main lines of work:

Corporate R&D organizations and their relation to academic laboratories.

Narrative Science examines the use of narrative in scientific research over the last two centuries.

UnMiSSeD studies the interaction between misinformation and science in societal debates using a mixed qualitative-quantitative approach.

Carl Li defended his thesis on 30 June 2015

This dissertation describes several studies concerning the research-teaching nexus in the sciences.

Our mission: a positive impact. Our vision: community. By involving the world around us in our education and research we make a positive impact. We do this by applying Open Science.

Big Science, commonly defined as conventional science made big in three dimensions, namely organizations, machines, and politics, brings a plethora of different stakeholders together, often for a long period of time. This includes policymakers, scientists, (scientific) managers as well as local “host”…

Astronomer and Marxist Anton Pannekoek was a remarkable figure. This book aims to study the connections between his life as a socialist theorist and as a pioneering scientist through the prism of Pannekoek's biography.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

After 20 years of police reform, Jasper De Paepe and Marleen Easton look back and discover what we can learn about partnerships between police and science in Belgium.

Data science is now growing fast in many places, but scholars at Leiden University have been developing data science techniques for a long time already. Thanks to their broad-based expertise, Leiden statisticians are currently combining the achievements in statistics with the latest methods of statistical…

LIACS is a partner in the EU Erasmus+ Curriculum Development for the Asian education system. The knowledge available in the field of Data Science and Artificial Intelligence education will be shared and adapted for the Asian market.

In a recent Physics World podcast, PhD candidate Felix Frohnert from Leiden University explains how his team uncovered hidden connections in scientific literature by using machine learning routines. With this information, it’s possible to predict promising new research ideas in quantum physics. Listen…

PhD candidates carry out a programme of independent research and additional limited) course work, culminating in production of a PhD thesis in typically 4 years.

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…

The Faculty of Social and Behavioural Sciences provides its ca. 5000 students with a thorough education in the social and behavioural sciences. The student population is very diverse and international in nature.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

The demolition of the high-rise building is ready. The remaining debris are removed and the area is cleared. For the demolition, the University applied the BREEAM evaluation method at the level of ‘Excellent’, which means that the demolition operations were carbon neutral and did not cause any form…

There are around 300,000 people in the Netherlands who donate blood on a regular basis. Women can give blood up to three times a year and men up to five times, resulting in approximately one million blood donations each year. Patients that receive this donated blood are already in a vulnerable condition,…
