Laboratory description

Reykjavik University Sleep Institute (RUSI) was established in 2020. The Sleep Center is a research center within the University of Reykjavik. The activities of the center are interdisciplinary and have within its walls employees of the Engineering Department, the Psychology Department, the Sports Department and the Computer Science Department of the RU. The dormitory also works with professionals in the education and health system, and its facilities are accessible to those involved in research related to sleep or daytime. These include employees at the Landspitali, Healthcare, Heart Protection, Better Sleep, and researchers from the University of Reykjavik and the University of Iceland.

In 2020, RUSI members received a 15-million Euro Horizon grant. The project is led by Dr. Erna Sif Arnardóttir, RUSI´s director. With almost 40 international collaborating partners from academia and industry, it aims to develop machine learning techniques to better estimate the severity and treatment needs for obstructive sleep apnea, to improve health outcomes and quality of life. With the commitment of the European Sleep Research Society and the Assembly of National Sleep Societies, with its over 8000 members, the project further aims to create new standardized international guidelines for sleep medicine.
