In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

Sinds vorig jaar staan er gekleurde pilaren op de universiteitscampus. Met deze ‘Act of Kindness Pillars’ wordt eenzaamheid bij studenten tegengegaan.

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…

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

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

The Faculty of Science

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.

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…

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.

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

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.

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…

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 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.

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…

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…

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.

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).

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.

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

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…

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…

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?

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

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…

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

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.

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.

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.
