In this article, Gerrit Dijkstra and Jos Raadschelders from the Institute of Public Administration, argue that Bosnia-Herzegovina survives so far on the basis of negative legitimacy.

Research into the wishes and (care) needs of older migrants

The unique geographic and temporal breadth of research at Leiden allows us to stimulate a shift from the classical Weberian mode of scholarly production that views historical development and modernization as emanating from Europe and the West to a multi-polar perspective that allows for more nuanced,…

Our scientists working with laboratory animals undergo training on animal experiments. In this training, researchers learn how to handle laboratory animals responsibly. Read more about the requirements we set for researchers working with laboratory animals.

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

The Pharmacy research group focusses on the development of predictive models to improve clinical drug efficacy and safety. We work on clinical problems that require further mechanistic understanding and strive for ultimate benefit to patients.

Built Environment and Domestic Material Culture in the Medieval and Post-Medieval Cyclades, Greece (13th – 20th Centuries AD)

The master's programme Industrial Ecology (joint degree Leiden University and Delft University of Technology) is unique in the Netherlands and one of the few programmes in the world combining natural science, engineering, and social science for science-based solutions for sustainability problems.

Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments. We apply our technology and methods to find biomarkers for key disease pathways and toxicity in clinical studies and in…

From 1550 onwards, a great interest in the natural world developed across Europe. This interest was not only stimulated by a growing knowledge of local flora and fauna, but also by the import of numerous exotic animal and plant species. Think, for instance, of researches and collectors like Gessner…

Aviation safety is of global concern. Yet 43% of countries worldwide lack the expertise and administrative capacity to ensure effective safety oversight of the aviation activities for which they are responsible under international law.

Both the Dutch government and the European Commission dedicate an increasing share of public funding for research and innovation to mission-oriented programs, aiming to facilitate sustainability transitions. These programs typically involve support fora range of different research activities, from the…

Research and education are two of the pillars the SAILS programme is built on and which we are keen to expand on. Communication of research to researchers, students, companies and other societal partners is another key element.
