Biography

Nehal Parikh, DO, MS joined the Section of Neonatology as an Associate Professor of Pediatrics and Principal Investigator in the Center for Perinatal Research at Nationwide Children’s Hospital in January 2011. Dr. Parikh completed his pediatrics residency at Winthrop University Hospital of State University of New York at Stony Brook. He completed a fellowship in neonatal-perinatal medicine at Thomas Jefferson University Hospital in Philadelphia and received an M.S. in Clinical Research from the University of Texas Health Science Center at Houston.
Dr. Parikh’s lab focuses on developing accurate and reliable brain segmentation methods for volumetric and diffusion tensor MRI and employing epidemiologic principles to elucidate the etiology, pathogenesis, and diagnosis of perinatal-neonatal brain injury in high-risk preterm and term infants.

Areas of Interest:

  • Perinatal-neonatal brain injury is a leading contributor of neurodevelopmental impairments. Our group’s goal is to improve the long-term quality of life of high-risk preterm and term newborns cared for in the neonatal ICU. Our work has been facilitated through generous support from the NIH (NINDS, NICHD, NCRR) and RINCH and enriched by collaborators in radiology, neurology, neuropathology, and developmental pediatrics. Studies designed to elucidate the etiology, pathogenesis, and diagnosis of perinatal-neonatal brain injury and aberrant brain development are facilitating targeted efforts at prevention and treatment of early insults. We have developed robust manual and automated brain MRI segmentation methods to objectively measure regional brain macro and microstructure in vivo using volumetric and diffusion tensor MRI. Using epidemiologic approaches, quantitative regional cerebral abnormalities are being correlated with antenatal, intrapartum, and neonatal clinical factors and functional neurodevelopmental assessments at and beyond 2 years of age.
