At Leiden University we work on the principle that our scientific research makes an important contribution to a safe, healthy, sustainable, prosperous and just world.

Leiden University and its Academic Medical Center (LUMC) have 30 research institutes, located within the University’s seven faculties. Our research strength can be summarised in five key areas:

  • Fundamentals of Science
  • Health and Wellbeing
  • Life Sciences
  • Law, Politics and Administration
  • Languages, Cultures and Societies

The research dossiers on this website are categorised into these five domains.

Praesidium Libertatis

Ever since the University’s foundation in 1575, we have been working together to develop, disseminate and apply scientific knowledge. Reflecting our motto Praesidium Libertatis (Bastion of Liberty), we also aim to be a reliable authority in both scientific and societal debates.

Research infrastructure, facilities and collections

Our research infrastructure, facilities and collections are among the best in the world. They are important determinants of our success and our scientific and societal impact. And in areas where our University occupies a unique position at national or international level, we are particularly careful in our approach to sometimes delicate research fields and scientific collections.

Disciplinary organisation, interdisciplinary collaboration

Much of our research aims to make the unknown known and to push the boundaries of existing research areas. Our research has a strong disciplinary basis across a very wide range of scientific fields.

Starting out from this basis, both disciplinary and interdisciplinary research is conducted by the 30 research institutes in Leiden and The Hague, and together with our three partners, Delft University of Technology, Erasmus University Rotterdam and the University of the Arts The Hague (with its Royal Conservatoire and Royal Academy of Art).

Across the borders of their institutes, faculties and universities, our researchers maintain close links with one another and with society, both national and international. They are guided by the highest ambitions of quality and integrity.
