Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

The focus of the Antiviral Pharmacology group led by Anne-Grete Märtson is optimizing antiviral therapy for different viral infections by conducting clinical trials and using innovative computational and dynamic laboratory methodologies.

In citizen science projects, citizens and scientists work together to develop new scientific knowledge.

The vision of the Business & Law Research Network (BLRN) is that company and insolvency law should facilitate and ignite societal collaboration and cooperation, to serve economic development and societal interests. Law should therefore be closely aligned with socio-economic developments, which requires…

The programme of the master specialisation Learning Problems and Impairments studies common learning problems such as dyslexia, hyperlexia and dyscalculia, as well as learning disabilities caused by AHDH, ADD or speech and language disorders.
