Special Interests:

My research interests have been in both clinical and basic science.  As a Neonatologist I have been interested in translational research in order to better understand neonatal cerebrovascular disorders, the mechanisms involved and to correlate the laboratory findings with the clinical findings.  I have been collaborating with our Physiologists (Dr. Leffler and Dr. Parfenova) for over 20 years. I have an extensive experience in studying hemodynamics of cerebral circulation in newborn pigs and in human neonates during physiological and pathological conditions such as acute and prolonged asphyxia, seizures, IVH, and, I have also investigated cerebrovascular manifestation of illicit drugs (maternal cocaine abuse) and the licit drugs that are commonly used in neonates. My published translational works include: 1) Role of prostanoids in asphyxia and reventilation; 2) Role of CSF cAMP as a predictor of neurological outcome of asphyxia; 3) The effects of maternal cocaine abuse on neonatal cerebral circulation; 4) The effects of indomethacin on neonatal cerebral circulation, 5) Endogenous production of CO during seizures, and 6) detection of brain–derived circulating endothelial cells (BCECs) in peripheral blood of infants as a biomarker of cerebrovascular injury.

At present my research activities includes: 1) Maternal substance abuse (MSA) and Neonatal abstinence syndrome (NAS), 2) Role of C-reactive protein (CRP) in neonatal disease, 3) immunization of preterm infants and 4) neonatal seizures.

I am Co-investigator of two NIH funded studies on Control of neonatal cerebral circulation.
