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…

In a virtual game environment, one of the positive effects of anonymity is the absence of one's prejudice toward others, which can give a person the freedom to change and experiment (Bartle, 2003). This project will adopt anonymity to be added to online cross-cultural collaborative learning in higher…

The concept behind GraspOS is to build the European Federated Open Metrics Infrastructure in a decentralised way, where: different types of data come together to create metrics; tools and services are developed to improve EU or global infrastructures but are also shared with national or institutional…

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.

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…

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?

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

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.

Apps to help people stop smoking, eat more healthily or exercise more are everywhere. eHealth programmes are abundant, yet they are often not accessible to people with lower incomes and levels of education. For her PhD research, Isra Al-Dhahir investigated how this could be improved.

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!

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.

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.

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.
