The master's specialisation Data Science: Computer Science at Leiden University provides students thorough knowledge and understanding of statistical and computational aspects of data analysis, including their application in databases, advances in data mining, networks, pattern recognition, and deep…

Hundreds of thousands of Dutch people suffer from pain caused by knee osteoarthritis and the number is rising fast. Prof. Jaap Harlaar specialises in clinical biomechanics. His research is helping improve osteoarthritis treatment. Harlaar has been appointed Medical Delta Professor and now holds posts…

There are eight institutes at the Faculty of Mathematics and Natural Sciences:

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

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

We are very happy to welcome you to spend a semester or year studying with us in the Faculty of Science. Here you will find information on your course schedules and course and exam enrolment.

This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

The aim of this study is to further develop the Open Science Monitor, which started as a pilot study.

This collection of seventeen essays takes its inspiration from the scholarly achievements of the Dutch historian Jan Lucassen. They reflect a central theme in his research: the history of labor.

The objective of this project is to understand the content and structure of science teachers’ knowledge and beliefs, and how these change in the context of pre-service teacher education and educational innovation.

After your graduation, Leiden University would love to stay in touch with you. Alumni are an important part of the university; with your experience we can improve the education, and you can be part of a valuable network full of knowledge and experience. Find out what options you have to stay in touch…

The Jaap Doek Children’s Rights Thesis Award is an annual award for the best thesis in the field of Children’s Rights granted by Defence for Children and the Department of Child Law of Leiden Law School.

What is and should be the role of universities in supporting business? How can business benefit more of relationships with science? And what is the role of policy makers in supporting a productive relationship between science and business? Professor Simcha Jong Kon Chin examines the interactions between…

The master’s specialisation Computer Science and Science Communication and Society at Leiden University bridges the gap between experts and the public by combining high quality research in computer science with extensive training in science communication.

Astronomers at ASTRON and Leiden University have used the LOFAR radio telescope to discover a 'brown dwarf' – a faint object more massive than Jupiter, but significantly less massive than the Sun. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover…

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

On 10 December Walter Burkard won the Jaap Doek Children’s Rights Thesis Award 2020 for his thesis on climate change and children’s rights. The prize for the best master’s thesis in the field of children’s rights is awarded every year by Defence for Children and the Department of Child Law of Leiden…

Anyone who creates a page for a magazine, a PowerPoint presentation, a brochure, a poster or dreams up an idea for an infographic is faced with important questions:

At Leiden University, we see open Science as the way to make a greater scientific and societal impact. There is also great momentum across the Netherlands for open science, and for good reason.

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…

Citizen science is an umbrella term. It describes a range of ways to involve citizens and societal actors such as NGOs in collaborative knowledge production: crowdsourcing research questions, collective data gathering and analysis (to name a few examples).

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…

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

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?

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 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…

We are very happy to welcome you to spend the fall semester, spring semester or full academic year studying with us at the Institute of Political Science Leiden or campus The Hague. Here you will find practical information as an exchange student.

The Science Council is an advisory committee to the Board of the Institute and consists of the full professors of the Institute.
