Douglas Ramsay, DMD, PhD, MSD
Professor and Chair, Oral Health Sciences
Professor, Orthodontics and Pediatric Dentistry
Adjunct Professor, Psychology
Dr. Douglas Ramsay received a B.A. in psychology from Franklin & Marshall College in 1979 and a D.M.D. from the University of Pennsylvania in 1983. He came to the UW in 1983 as a senior fellow and in 1985 entered the UW’s NIH-funded Dentist-Scientist Training Program, which supported his doctoral studies in psychology (PhD, 1988) and specialty training in orthodontics (MSD, 1990). He joined the UW faculty as an Assistant Professor in 1990 and was promoted to the rank of Professor in 2001. Ramsay served as Chair of the Department of Dental Public Health Sciences from 2003-2011. In 2011, the Departments of Oral Biology and Dental Public Health Sciences were merged to form the Department of Oral Health Sciences and Ramsay currently serves as the Chair of this department. Ramsay is a professor of Oral Health Sciences, Orthodontics, and Pediatric Dentistry. He also has an adjunct appointment in the department of Psychology. Since 1991, Dr. Ramsay’s research has been continuously funded by the National Institutes of Health. In addition to numerous research grants, he was the recipient of a Research Career Development Award from the National Institute of Dental and Craniofacial Research. Dr. Ramsay is a Diplomate of the American Board of Orthodontics and has been Director of the UW’s Regional Clinical Dental Research Center since 2007.
Academic and Clinical Activities
Dr. Ramsay teaches and supervises students at the undergraduate, graduate, and post-doctoral levels. Each year he directs a didactic seminar for the graduate students in Pediatric Dentistry and Orthodontics and provides guest lectures in other courses. As a board-certified orthodontist, he teaches and supervises patient care in the graduate orthodontics clinic throughout the year.
Dr. Ramsay’s research interests are broad and he has a record of conducting both basic and clinical research. A primary research interest of his is in the area of behavioral pharmacology with a focus on the mechanisms underlying the development of drug tolerance. His scientific interests include: mechanisms of drug tolerance, behavioral pharmacology, patient compliance, learning and memory, regulatory behavior, tooth circulation, addictive disorders, pain (mechanisms and psychophysics).
