Hanne Siri Amdahl Heglum

Postdoctoral Fellow

–

NTNU, Dept. of Mental Health

Postdoctoral fellow in the Trondheim Sleep Group. I work in the AI-MENT project, which is a collaboration between the Department of Mental Health and the Department of Computer Technology. Our goal is to develop and explore modern technological tools for improving services in mental health care, with a particular focus on methods relating to sleep. Hanne-Siris PhD topic was the use of a non-contact radar sensor for deriving information about sleep from measurements of movement patterns. She is particularly interested in studying connections between neurological sleep physiology and easily measurable signals (such as body movement), and hope that more knowledge in this field can contribute to making objective sleep measurement easier and more accessible to all.
