Faculty MentorshipDr. Oken is not available as a mentor for 2016-2017.
BackgroundDr. Oken received a B.A. degree in math from the University of Rochester in 1974 and an M.D. degree from the Medical College of Wisconsin in 1978. After completing a medical internship at the University of Illinois Affiliated Hospitals, he served as resident in Neurology from 1980-1983 at Boston University Medical Center. From 1983-1985 he was a Fellow in Electroencephalography and Evoked Potentials at Massachusetts General Hospital and Fellow in Neurology at Harvard Medical School. Since 1985, he has been a member of the faculty at Oregon Health & Science University. He has a strong interest in quantitative analysis of data from human experiments and obtained a PhD in Systems Science in 2016 from Portland State University.
Research InterestsDr. Oken’s research interests include cognitive changes related to aging, Alzheimer’s disease, and complementary and alternative medicine therapies for neurological disorders. Research methodologies he utilizes center in cognitive neuroscience with a focus on attention, stress, and on human neurophysiology. In addition to directing a collaborative complementary medicine center, Dr. Oken is associate director of the Oregon Health & Science University Layton Aging and Alzheimer Disease Center. He is an active researcher who also regularly sees people with various cognitive disorders, primarily dementia and is medical director of the OHSU Clinical Neurophysiology Department. Dr. Oken has published 150 articles, abstracts and book chapters in his areas of interest.
