Education and Training

Dr. Davis joined the University of Maryland team in August 2013. Originally from Michigan, she attended the University of Michigan as part of the Inteflex combined undergraduate and medical school program, earning her B.S. in Microbiology in 2001 followed by her M.D. in 2005. She completed her Pediatrics Residency at the University of California San Francisco (UCSF) in 2008 and served as Chief Resident from 2008-2009. She worked as a Pediatric Critical Care Transport Physician and Hospitalist at UCSF for one year then went on to do a fellowship in Neonatology as part of the Harvard Neonatal-Perinatal Medicine Program at Boston Children's Hospital (2010-2013). During fellowship, Dr. Davis earned a Masters in Medical Science (MMSc) through the Scholars in Clinical Science Program at Harvard Medical School, graduating in 2013.


Dr. Davis' research interests are related to the effect of intermittent hypoxia on development and growth of preterm neonates as well as optimizing respiratory status at discharge. Her main areas of interest include:

  • Car Seat Tolerance Screen (CSTS) - evaluating the utility of the CSTS to identify infants at risk for adverse cardiopulmonary events in the semi-upright car seat position.
  • Intermittent hypoxia (IH) - looking at the effect of IH on growth and respiratory outcomes.
  • Silent Aspiration - evaluating timing of feeding maturity and resolution of silent aspiration in former preterm infants.

Dr. Davis is involved in numerous studies related to discharge readiness for vulnerable preterm and low birth weight infants. She is the faculty advisor for the Child Passenger Safety Program at the University of Maryland Children's Hospital and is a consultant for numerous Child Passenger Saftey programs in the US and internationally. She is a member of the Society for Pediatric Research. She was named a "Top Doctor" in Neonatology by Baltimore Magazine on numerous occasions. She was named Director of Resident Research for the Department of Pediatrics in 2019 where she oversees the longitudinal research track. Dr. Davis became Associate Program Director (APD) of the Neonatal-Perinatal Fellowship in 2020, with a focus on  NICU fellowship research support.
