About Leslie A Parker
RESEARCH/SCHOLARSHIP
Dr. Parker’s research involves nutritional support of the premature infant with an emphasis on breastfeeding infants in the neonatal intensive care unit (NICU). She has been funded by the National Institute of Nursing Research to study (1) the risks and benefits of routine gastric residual aspiration and evaluation in very premature infants and (2) the optimal timing of initiation of milk expression following the delivery of a very premature infant. She recently received a 2018 Research Opportunity grant to study strategies to increase lactation success in mothers of extremely premature infants. She received a UF Term Professorship award in 2017.
SERVICE
Dr. Parker is board certified as a neonatal nurse practitioner by the National Certification Corporation. She has an active practice as a neonatal nurse practitioner in the NICU at UF Health.
