Main areas of research interest:

• Sleep, both basic mechanisms and clinical studies
• Circadian rhythms, shift work, bright light treatment
• Depression, serotonergic mechanisms
• Treatment of chronic insomnia, e.g. stimulus control, sleep restriction, bright light
• The relationship between sleep, circadian rhythm, depression and serotonin

Teaching/lectures/popularization:

• Teaching for students in medicine, physiology, psychology, nursing, and odontology.
