Eivind Schjelderup Skarpsno

About

Eivind Skarpsno is a Top-level Researcher (1183/Professor level) at the Department of Public Health and Nursing and leads the research group Musculoskeletal Health, Sleep and Physical Activity. Most of his work centers on understanding the role of insufficient sleep and sleep disorders in the development of various diseases, as well as identifying strategies to improve sleep quality across different patient populations, with a particular emphasis on the interplay between sleep and pain.

Skarpsno heads the work package Working time, sleep, and health in STUNTH, a research project exploring the links between work conditions and health among different hospital employee groups. He is also deputy leader of the program area Health- and welfare technology, a collaborative initiative between NAV, Central Norway Regional Health Authority, and NTNU. This partnership is based on a long-term strategy to develop and strengtehn research and expertize in areas where NAV and the healthcare services have specific knowledge needs.

Beyond his research leadership, Skarpsno hosts the Norwegian research podcast Årsak–Virkning (Cause–Effect), where he discusses scientific insights and their real-world implications. He also teaches epidemiology at the Faculty of Medicine and Health Sciences.
