OHSU Sleep & Mood Disorders Laboratory

Home of internationally-recognized research on melatonin, circadian rhythms and disorders related to the body clock, we aim to expand understanding of the human internal body clock and to develop and refine treatments for body clock disorders.


Sleep & Mood Disorders Laboratory

Since its inception in 1982, the Sleep and Mood Disorders Laboratory has focused on studies of circadian rhythms ("body clocks") and how they are affected by melatonin and light. The Laboratory continues to refine the understanding of how circadian rhythms govern the sleep-wake cycle and how melatonin can be used as a treatment for misalignments between circadian rhythms and sleep.
