Is it possible to formulate a new conceptual foundation for attributing an evaluative role to historiography of science, without relinquishing the historiographic sensitivity of recent work in the discipline?

We also conduct research to make meaningful contributions to society. For instance, by talking about our research, contributing to community projects or by inviting people to help us with our research. Scroll down and discover how Science and Society can mutually reinforce each other.

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

Principles of Environmental Sciences provides a comprehensive picture of the principles, concepts and methods that are applicable to problems originating from the interaction between the living and non-living environment and mankind. Both the analysis of such problems and the way solutions to environmental…

The overall objective of ECS is to widen and strengthen the European Citizen Science community through capacity building and awareness raising activities such as the creation of a European Citizen Science Academy and the establishment of a network of 28 ECS Ambassadors.

What tools can be applied to measure the output, outcome and impact of science communication efficiently and effectively?

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 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.

How can we bridge the gap between experts and the general public?

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

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

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

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 mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

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.

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

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…

Social Science Matters is an online variant on London’s famous Speakers’ Corner – a platform for the researchers in the various disciplines in the Faculty of Social and Behavioural Sciences to react to the news. This soapbox gives our social scientists an opportunity to voice their opinions on current…

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…

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.

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 two-year master’s programme in Computer Science at Leiden University offers seven specialisations ranging from AI to Bioinformatics and Data Science. The programme combines excellent theoretical teaching with possibilities for applied work with industrial relevance.

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 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…

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

The Citizen Science Lab brings together scientists, citizens and community stakeholders to arrive at new insights for both science and society through citizen science.
