Using artificial intelligence is more complicated for the government than for companies. Bram Klievink, Professor of Public Administration, aims to identify the problems and find solutions.

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

Bram Geurds (20) is fascinated by politics. When he was 12, a political debate on TV caught his attention. And he decided he wanted to be mayor one day. Unsurprisingly, Bram is studying political science and is politically active. It might seem like he’s on course to become a professional politician.…

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Parasitic worms and stomach bacteria suppress immune reactions such as allergic responses. Parasitologist Hermelijn Smits and lung specialist Christian Taube from the LUMC are trying to learn from these micro-organisms.

The infectious diseases malaria and tuberculosis are responsible for 2.1 million deaths every year. Leiden researchers are currently testing a new tuberculosis vaccine.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

In this article, Friso Selten and Bram Klievink explore how public organisations strategically manage the adoption of AI.

In this project, researchers and lecturers from LUCAS, ICLON and UBL join forces to publish expertise and experience in the field of machine learning and AI as open learning materials for secondary education.

In this thesis we construct an extension associated with the Furstenberg compactification of symmetric space of noncompact type. From this extension we get a cycle in equivariant KK-theory representing the extension. The construction of the extension and the corresponding cycle is a generalization of…

On Friday 17th September 2021 an inaugural lecture was held by prof.dr.ing. Bram Klievink entitled: 'Hollen én stilstaan: hoe data en digitalisering de overheid veranderen'.

Our centre seeks to form a community which connects a network of academics of various disciplines, with organisations interested in public governance.

The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…

Health workers have always sought ways to fight disease in vulnerable groups in the population. It is now clear that such research also benefits more prosperous countries. African worm infections and innovative thermometers have shown Leiden researchers how to fight diseases of affluence and keep health…

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

What will it be like to study at Leiden University in 2075?

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

Lots of efforts are being made to promote open science practices in scholarly publishing. However, information on the openness of scholarly journals is highly fragmented. There are various data sources that provide information on specific aspects of openness, but there is hardly any integration of these…

Across Leiden University and LUMC, people are taking steps to put academia into motion. Learn what they are doing, why it matters and their tips for colleagues.

In this paper, Sarah Giest and Bram Klievink highlight the effects of AI implementation on public sector innovation. This is explored by asking how AI-driven technologies in public decision-making in different organizational contexts impacts innovation in the role definition of bureaucrats.
