Rebecca A. Christie, MPM

Study Coordinator

Rebecca joined the NICU2HOME team in early 2019 as a research study coordinator responsible for gathering and managing data for the Friends of Prentice sponsored study, “Supporting Families of All Premature Infants at Prentice Women’s Hospital from Admission through Discharge.”  This study evaluated the effectiveness of the NICU2HOME smartphone app in helping parents navigate the complexities of the NICU and transition home. Rebecca now helps oversee an expanded offering of NICU2HOME at Prentice, while also contributing to relevant maintenance, design, and innovation efforts of the app team.

Rebecca received her BA from Vanderbilt University and her MPM from the University of Maryland. Prior to her work with NICU2HOME, Rebecca enjoyed her time as a program auditor in the areas of child support and child welfare services. Her other professional interests include studying the partnership of government and private organizations in the delivery of social services. Despite her interest in the public sphere, a dramatic second place finish in her run for Junior Mayor of Cincinnati ended her political aspirations, so she shifted her attention to social policy work.
