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:

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

An analysis of pot decoration and hut distributions from the Central European Neolithic communities of Elsloo and Hienheim.

How do museum visitors interpret the authenticity of museum objects? How can we support visitors' meaningful interactions with real objects?

The ability to collect and interpret huge quantities of data has become indispensable to society and academia. Leiden University is a knowledge and expertise centre for data science that places the emphasis on interdisciplinary collaboration and innovation.

To argue that people can control the relative contributions of goal-driven and stimulus-driven processes to decision-making and action selection.

Although science and education have top priority, exploratory projects with companies, governments and NGOs generate ample opportunities in terms of societal challenges, science strategy, valorisation and research collaboration. In the LIACS Applied Data Science Lab, our master's students and graduates…

This catalogue is the result of the EU_CUL project (2018-2021), which explores the use of cultural heritage in Europe for fostering academic teaching and social responsibility in higher education.

Research and design are becoming more and more important in international science education. In The Netherlands, two recently introduced subjects focus on research and design activities in the classroom: O&O (research and design) and NLT (nature, life and technology). This research aims to look at what…

The Leiden Computational Network Science Lab (CNS Lab) researches methods for knowledge discovery from real-world network data.

Get to know us through our online and in-person events for prospective students!

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

From where litter ends up to which languages are spoken in Leiden and The Hague: over 50 interesting, surprising, complex and entertaining questions were sent in for the Citizen Science project to mark our 444th anniversary. Not one but two Citizen Science projects will be starting this year in Leiden…

A fun challenge full of energy, teamwork and good vibes? On Saturday 21 June 2025, the Leiden Science Run was back!

On this page you find all the ways through which the Institute of Psychology aims to foster Open Science.

Citizen science has recently become a widely used term, but what does it mean exactly? How does citizen science compare to crowdsourcing? And where does community archaeology stand in this discussion?

Sonic Modernities situates Southeast Asian popular music in specific socio-historical settings, hoping that a focus on popular culture and history may shed light on how some people in a particular part of the world have been witnessing the emergence of all things modern.

The Institute of Political Science is a vibrant department with nearly 70 academic staff in Leiden and nearby The Hague.

In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.

Leiden University will be recording a brand-new series of podcasts in 2019: Science Shots. Our top scientists will talk about their research in less than 15 minutes. Tip: something to enjoy on the train journey between Leiden and The Hague, our two University cities!

In citizen science projects, citizens and scientists work together to develop new scientific knowledge.

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

The Department of Archaeological Sciences seeks to achieve the highest standards of excellence in science-driven education and archaeological research across the globe and across all periods.

'Dialogues Between Artistic Research and Science and Technology Studies', edited by Henk Borgdorff, Peter Peters and Trevor Pinch, will be published by Routledge on November 18

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.

The master’s specialisation Bio-Pharmaceutical Sciences and Science Communication & Society at Leiden University is a two-year programme which combines research training in chemistry with one in techniques of communication.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

The main aim of this dissertation was to provide insight into possible subtle forms of bias in youth socialization by various socializing agents in the Netherlands, and exploring new ways to document bias. Additionally, it addresses the importance of using sound statistical methods for calculating effect…

With the emergence of new methods and technologies such as improved DNA analysis and big data, archaeological research has changed radically in recent decades. The researchers from the Department of Archaeological Sciences at the Faculty of Archaeology use new scientific knowledge to answer fundamental…

At the Institute of Political Science we value our alumni. We can learn from you, and would like to contribute to your further development. And, of course, we want to lend a hand in connecting ‘our’ political scientists all over the world.
