Assistant Professor of Pediatrics joined Stony Brook Medicine in 2013. He completed his fellowship training at Golisano Children's Hospital University of Rochester where he was recognized as the Bradford Fellow by the Department of Pediatrics. He is board certified in Pediatrics. His research interest during his fellowship was in hyperoxic injury to the neonatal lung. He tested the hypothesis that cumulative oxygen, represented as concentration and duration of oxygen exposure (i.e. "oxygen area under the curve"), can be used to define levels of oxygen toxicity sufficient to impair host response to viral infection in mice - funded by NIH T32 Department of Pediatrics grant, "Bench to Bedside to Curbside."

Dr. Maduekwe's future interest is in improving the care of the neonates in our region through perinatal outreach program.
