Dr. Williamson is a clinical psychologist and Assistant Professor of Psychiatry and Pediatrics at Children’s Hospital of Philadelphia (CHOP) and the University of Pennsylvania (Penn) Perelman School of Medicine, with appointments in Child and Adolescent Psychiatry and Behavioral Sciences, PolicyLab, the Center for Pediatric Clinical Effectiveness, and the Sleep Center at CHOP. Her work leverages pediatric sleep as a modifiable factor that can promote positive development and prevent child physical and behavioral health problems. Specifically, her research focuses on (1) understanding socio-ecological determinants of pediatric sleep health disparities (2) behavioral approaches to promote pediatric sleep health and treat sleep problems in primary care and in partnership with community organizations. She serves as a board member for the Philadelphia-area Beds for Kids program (, which provides beds, bedding, and sleep health education to children and families living in poverty and without an individual child bed. In addition, Dr. Williamson is a member of the Society for Pediatric Research and serves as Associate Editor for Sleep Health, the official journal of the National Sleep Foundation. She is a two-time NIH loan repayment award recipient and was awarded a Sleep Research Society Foundation Career Development Award in 2018.
