Mattina Davenport, PhD, is a pediatric sleep medicine and population health scientist investigating pediatric sleep disparities. She is a Principal Investigator in the Center for Child Health Outcomes Research at the Abigail Wexner Research Institute at Nationwide Children's Hospital, and an Assistant Professor of Pediatrics at The Ohio State University. She leads the SLEEP Empowers Lab, where her research focuses on multigenerational family sleep health, addressing and closing systemwide sleep care gaps, and population health prevention strategies. Her foundational NIH NHLBI K01 funded research successfully utilized clinical health informatics (e.g., machine learning, bias mitigation methods, and natural language processing) to build clinical prediction models. Her current research portfolio has expanded to employing methods for defining and advancing the emerging subfield of precision population sleep health. By integrating advanced public health informatics, behavioral sleep medicine, community-based participatory methods, and prevention science, her work dynamically maps the patient sleep care journey to identify exactly where and why high-needs families experience clinical attrition across the lifespan. Furthermore, Dr. Davenport’s lab serves as the founder for the SLEEP Friendly Cities initiative, empowering communities to co-create solutions and utilize digital virtual laboratories to safely simulate and optimize equitable, place-based sleep health prevention strategies prior to real world implementation.
