Biographical Info

Research Areas

Major areas of research include neonatal hyperbilirubinemia (examination of free bilirubin levels in infants, effects of bilirubin on neutrophil function, free bilirubin levels following indomethacin/ibuprofen administration), free fatty acids (level in perinatal hypoxia, levels in infants with patent ductus arteriosus), Sudden Infant Death Syndrome, and parental stress in the intensive care nursery.

Research Highlights

  • Examined newborn sleep position and SIDS
  • Identified effect of race and ethnicity on breast feeding
  • Demonstrated spectral analysis of heart rate variability in  preterm infants
  • Emphasized concurrent risks in SIDS
  • Demonstrated developmental outcomes of late preterm infants
  • Showed anti-inflammatory activity of bilirubin on neonatal neutrophils

Scholarly Activities

  • Program Director, Division of Neonatology
  • Director, SIDS Center of New Jersey
  • Director, High-risk Infant Follow-up Program
  • Director, Infant Apnea Center
