Dr. Narayanan obtained his BS in Physics in 1972 from Washington University in St. Louis, Missouri. He completed graduate studies in mathematical physics at Princeton University, where he received his MA in Physics in 1976. He received his MD from Louisiana State University Medical School, New Orleans, Louisiana, in 1981, and completed his internship and residency in pediatrics at the Johns Hopkins Hospitals, Baltimore, Maryland. Between 1983 and 1986, he served as resident in Neurology and Child Neurology at Washington University, St. Louis, Missouri
(Barnes Hospital and St. Louis Children's Hospital). After completing his residency, Dr. Narayanan returned to the Johns Hopkins Medical Institutions as a research fellow and faculty member, working in the laboratory of Dr. Gihan Tennekoon, studying the expression and regulation of the peripheral myelin P2 protein gene. He joined the Child Neurology division at the Children's Hospital of Pittsburgh in 1990, where he remained until 2003 as Associate Professor of Pediatrics and Neurology. In 2003, Dr. Narayanan moved to Phoenix as a member of the Child Neurology division at Barrow Neurological Institute.
His research interests include the neurobiology of genetic disorders (genes to pathogenesis), cell adhesion molecules and synapse formation. He is engaged in a number of active research projects and has published extensively in the neuroscience literature.
