Get to Know Me

Prior to joining the Nemours, Dr. Viswanathan served as a faculty member of the Innovative Feeding Disorders Program at Nationwide Children’s Hospital, Columbus, Ohio. His academic vision is to develop translational clinical research protocols to transform dysfunctional feeding patterns in NICU infants. He has published more than 25 peer-reviewed articles and is an active peer reviewer for a dozen leading pediatric journals. He is a fellow of the American Academy of Pediatrics and a member of the Dysphagia Research Society.

Why I Treat Children

After my extensive pediatric training in India, UK and the US, I found looking after and caring for critically ill newborn children to be my calling and decided to become a neonatologist. There is nothing more satisfying than watching an unwell newborn baby get better and go home. I believe in the adage “There are two things we should give our children: one is roots and the other is wings.” Being born early or sick is not something we can control, but I strive to provide the best possible care to enable them to hold their ground in the world outside of the NICU. 

What I'm Passionate About

There have been many advances in neonatal care in recent years. I am an avid researcher and believe in evidence-based practices to provide the most up-to-date care. I am particularly passionate about preventing and solving feeding and nutrition-related disorders in neonates as I strongly believe that optimizing early nutrition and growth is critical for the long-term health of newborn babies.

How I Try to Make A Difference

No two babies are the same. This is especially true in neonatology. I treat every baby with passion and purpose by putting the babies and their families at the center of everything by sharing timely information and building trust. I believe in working collaboratively with my team and partnering with parents for the best possible outcome for each and every baby.
