Alfred Lewy, M.D., Ph.D.

Dr. Lewy is a board-certified psychiatrist with a Ph.D. in Psychopharmacology. He is the Richard H. Phillips Professor and Senior Vice Chair of Psychiatry. He is also Professor of Ophthalmology, and Physiology/Pharmacology at Oregon Health and Science University. Dr. Lewy was born in Chicago, Illinois, and received his B.S., M.D., and Ph.D. from the University of Chicago. He is internationally known as a pioneer in the field of human Chronobiology, melatonin and light, publishing ground-breaking articles on melatonin, light and winter depression. His work has given psychiatry a new perspective on the physiology of sleep and mood disorders, which is also relevant to the problems of blind people, as well as individuals who must cope with the discomforts of shift work and jet lag. Dr. Lewy's contributions to the field of melatonin physiology and light have literally opened up a whole new approach to the treatment of chronobiologic sleep and mood disorders.

Jonathan Emens

Jonathan Emens, M.D., D.A.B.S.M.

Dr. Emens is an Assistant Professor of Psychiatry at Oregon Health & Science University. He received his B.A. from Oberlin College, M.D. from University of Massachusetts Medical School, and completed his Internship and Psychiatry Residency at OHSU. Dr. Emens' clinical focus is on the diagnosis, analysis and treatment of sleep disorders in OHSU's Sleep Medicine Program. He is board certified in Psychiatry and Sleep Medicine, and provides supervision for psychiatry residents. He is also a principle investigator in a research study titled "Genetics of Morning/Evening Types in the Blind/Sighted." The goal of this research is to utilize recent developments in the molecular biology of circadian rhythms to better understand the physiologic and genetic basis of diurnal preference in sighted humans and 24-hour sleep/wake schedule disorders in the blind. Dr. Emens is also conducting a study titled "Evaluation of Circadian Misalignment in Non-Seasonal Major Depression", investigating a connection between depression and shifts in circadian rhythms.
