Dr. Ariel A. Williamson is a clinical psychologist and Diplomat in Behavioral Sleep Medicine (DBSM) with expertise in pediatric sleep health inequities and behavioral interventions. Dr. Williamson is an assistant professor of child behavioral health at University of Oregon’s Ballmer Institute for Children’s Behavioral Health in Portland, Oregon, which is dedicated to addressing youth mental health disparities. Prior to joining the Ballmer Institute, Dr. Williamson was an assistant professor of psychiatry and pediatrics at Children’s Hospital of Philadelphia (CHOP) and the University of Pennsylvania Perelman School of Medicine. Dr. Williamson earned her doctorate in clinical psychology from the University of Delaware, completed her clinical internship at CHOP in integrated behavioral health, and completed a T32 fellowship in Behavioral Sleep Medicine at CHOP and University of Pennsylvania.

Dr. Williamson’s research uses a socio-ecological approach to understand how multiple factors (child; family; school; neighborhood; environmental and socio-cultural context) contribute to child sleep problems, sleep health inequities, and developmental outcomes. Dr. Williamson’s intervention research applies implementation science principles and community-engaged methods to promote pediatric sleep health and treat sleep problems in primary care and in partnership with community organizations. Dr. Williamson is a board member for the Philadelphia-area Beds for Kids program, which provides beds, bedding, and sleep education for children living in poverty and without an individual bed. Dr. Williamson is a member of the Society for Pediatric Research and an Associate Editor for Sleep Health: the official journal of the National Sleep Foundation. She is also a committee member for the American Heart Association’s LIFESTYLE Sleep Health Committee of the Council on Lifestyle and Cardiometabolic Health. Dr. Williamson’s research has been funded by NICHD (K23HD094905), NHLBI (R01HL163798), the Sleep Research Society Foundation, and the American Academy of Sleep Medicine Foundation. In 2023, she received the American Thoracic Society’s Carole L. Marcus Outstanding Achievement Award, which recognizes early career accomplishments in pediatric sleep and respiratory neurobiology.
