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…

Choice is at the very heart of politics. War or peace, left or right, liberty or security, sovereignty or integration, consensus or conflict: choices matter. Study power and politics as they impact everyday lives in a topranked, selective programme. By doing a master's in Political Science in Leiden…

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?

The master’s specialisation Bio-Pharmaceutical Sciences and Industrial Pharmacy at Leiden University examines safety and quality control in the production of medicinal products, and prepares students for a career in Quality Assurance and Quality Control in the biotechnological and pharmaceutical ind…

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?

The Leiden Science Young Talent Award is awarded yearly to a student who completed their bachelor’s degree with an excellent thesis.

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

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,…

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…

From the largest numbers to the smallest molecules and from the oldest galaxies up to the latest algorithms, explore our standout discoveries and most inspiring collaborations from the past year!

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

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

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

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 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…

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.

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

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…

Open Science verandert de manier waarop onderzoek wordt gedeeld en wordt samengewerkt. Anna van ’t Veer won een award voor haar Open Science-activiteiten.
