Dr. Ariel Williamson is a licensed clinical psychologist and diplomat in behavioral sleep medicine. Her research leverages pediatric sleep as a modifiable factor that can promote positive development and prevent child physical and behavioral health problems. Specifically, her work focuses on (1) using a socio-ecological approach to understand how multiple factors (child; family; school; neighborhood; environmental and socio-cultural context) contribute to child sleep problems and sleep health inequities, and (2) applying implementation science principles to promote pediatric sleep health and treat sleep problems in primary care and in partnership with community organizations. Dr. Williamson serves on the board of the non-profit Philadelphia-area Beds for Kids program, which provides beds, bedding, and sleep education for children living in poverty and without an individual bed or sleep space. She also serves as a sleep expert for the Pediatric Sleep Council, which provides free, evidence-based information about early childhood sleep for families and clinicians. Dr. Williamson is a member of the Society for Pediatric Research and Associate Editor for Sleep Health, the official journal of the National Sleep Foundation. Her research has been funded by the National Institute of Child Health and Human Development, the National Heart, Lung, and Blood Institute, the Sleep Research Society, and the American Academy of Sleep Medicine Foundation.
