Leiden pharmacy and pharmacology has risen to 17th place in the QS World University Rankings by Subject. In 2016 it was in 21st place in this annual ranking of leading universities in 46 disciplines.

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…

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

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.

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.
