Dr. AlrifaiWael Alrifai, M.D. 
Dr. Alrifai's research is focused on using health information technology to improve care in neonatal and pediatric populations with a focus on quality, safety, and reduction of cost. In his most recent effort, he developed and evaluated novel clinical decision support systems to improve the safety and efficacy of nutrition in premature infants.

Englehardt MDBarbara Engelhardt, M.D.
Dr. Engelhardt's funded research has included a study of cord blood levels of inflammatory cytokines in smokers and non-smokers, a study assessing infants in opiate withdrawal for the presence of pain, a study assessing the efficacy of behavioral interventions for substance abuse (prevention in children of addicted mothers), and studies evaluating of the use of regional oximetry in neonates.

Susan GuttantagSusan H. Guttentag, M.D.
Dr. Guttentag is Director of the Division of Neonatology. Her research is in the area of lung cell biology, specifically in the production, assembly, and secretion of pulmonary surfactant from the alveolar epithelial type 2 cells. Her work currently involves understanding the cellular trafficking pathways necessary to deliver surfactant-specific components to the surfactant storage organelles known as lamellar bodies.

Leon Dupree HatchLeon Dupree Hatch, III, M.D.
Dr. Hatch's research focuses on improving the safety of mechanical ventilation and respiratory care in the NICU. His research uses methods from implementation science, quality improvement and epidemiology. Recent and ongoing work has focused on the safety of endotracheal intubation in newborns, the epidemiology of mechanical ventilation use in the NICU and the interplay of sedation and mechanical ventilation in newborns. In addition to his research, Dr. Hatch leads multiple quality improvement teams in the NICU.

Dr. KrakauerMaria Gillam-Krakauer, M.D.
Dr. Krakauer is an assistant professor in neonatology. Her clinical research focuses on patent ductus arteriosus and near-infrared spectroscopy. She is associate director of the neonatal-perinatal medicine fellowship and oversees the resident and student experiences in the NICU. She organizes the neonatal fellow core curriculum and simulation experiences. Her education research includes curriculum development for post-graduate medical trainees in neonatology including “NeoFlip,” a nationwide collaboration with other neonatal program directors to design a national neonatal curriculum using the flipped classroom approach; in vivo simulation for interns in the NICU; using simulation to improve team communication in unanticipated acute events in the NICU; and a curriculum to teach fellows how to counsel parents anticipating an extremely premature birth.

Lehmann MDChristoph Lehmann, M.D.
Dr. Lehmann’s research effort lies in applied clinical informatics and focuses on the use of health information technology and improved patient care, safety, and outcomes. He has developed, implemented, and evaluated several health IT tools that have been demonstrated effective in reducing provider errors, reducing costs, decreasing unnecessary medication usage, and improving safety. Learn more about Dr. Lehmann's research.

Stephen Patrick Stephen W. Patrick, M.D., M.P.H., M.S.
Dr. Patrick research is focused on improving public health systems to optimize maternal and child health. He is a health services researcher with a focus on Medicaid policy, eliminating healthcare-associated infections, substance-exposed infants and neonatal abstinence syndrome. Learn more about Dr. Patrick and his research.

Jeff Reese MDJohn Jeffrey Reese, M.D.
Dr. Reese's research interests include regulation of embryo implantation, mechanisms of term and pre-term labor, prostaglandin biology, and regulation of the ductus arteriosus. Learn more about Dr. Reese's research.

Bill Walsh MDWilliam Francis Walsh, M.D.
Dr. Walsh's clinical research focuses on determining the optimal ways to care for critically ill infants. Recent projects include a randomized trial of nitric oxide for prevention of chronic lung disease in premature infants and a randomized trial of fetal surgery vs. post-natal repair of myelomeningocele. He is presently looking at the effects of state-wide screening for critical congenital heart disease on outcomes. He is also studying the use of erythropoietin to ameliorate injury from hypoxic ischemic encephalopathy and working with colleagues in nursing to determine the reason for the racial disparity in pregnancy outcomes in Tennessee and the effect of targeted interventions.

Dr. WeitkampJörn-Hendrik Weitkamp, M.D.
Dr. Weitkamp is board-certified in Pediatric Infectious Diseases and Neonatal-Perinatal Medicine and serves as Director for Patient-Oriented Research in Neonatology. Dr. Weitkamp oversees a large number of clinical trials and translational research projects. Studies include the use of erythropoietin to prevent or reduce brain injury in babies cooled for encephalopathy, the effectiveness of aerolized surfactant in reducing intubation in preterm babies with respiratory distress, development of non-invasive diagnostic devices for developing countries, improving the treatment of infections and prevention of necrotizing enterocolitis.  Learn more about Dr. Weitkamp's research.
