Cynthia Marie Zettler-Greeley, PhD

Senior Research Scientist/Biostatistician

ֲý Children's Hospital, Delaware 1600 Rockland Road Wilmington, DE 19803

Biography

Cynthia Zettler-Greeley, Ph.D., earned her doctorate in developmental psychology from Georgia State University. Following postdoctoral study at the University of Wisconsin-Madison, Dr. Zettler-Greeley joined ֲý Children's Health as a research scientist, where she conducted efficacy studies on early language and literacy interventions. In 2015, this work led to a federal research grant through the Institute of Education Sciences to examine the efficacy of the ֲý BrightStart! early literacy program, in collaboration with investigators at The Ohio State University. Since 2017, Dr. Zettler-Greeley has led a team of scientists responsible for research and evaluation efforts of the ֲý Center for Health Delivery Innovation, where she studies how digital health technologies and therapeutics can be used to improve access to care and children's outcomes across a variety of clinical conditions. In collaboration with ֲý telemedicine pediatricians, Dr. Zettler-Greeley has explored the use of telemedicine for maintaining patient access to care during the pandemic and other natural disasters. Continued work examines the pivotal role of telehealth for enhancing patient care and healthcare quality within a pediatric health system. Presently, Dr. Zettler-Greeley is part of a collaborative team embarking on the implementation of a hospital in the home program. A pilot study examining the feasibility and accuracy of wireless digital sensors for monitoring pediatric patient's heart rate and oxygen levels is in development. Dr. Zettler-Greeley's research has been presented at international academic research conferences and published in peer-reviewed journals.
