Advanced Fellowship in Neonatal and Infant Feeding Disorders

Advanced Fellowship in Neonatal and Infant Feeding Disorders

The Neonatal and Infant Feeding Disorders Fellowship is a one year, advanced program targeted to understanding the mechanisms of developmental gastrointestinal motility and neonatal and infant feeding disorders.

This one year advanced fellowship is a unique, one-of-a-kind fellowship. The fellowship will take place within the Neonatal and Infant Feeding Disorders Program, which was founded at Nationwide Children’s Hospital in 2002 by Dr. Sudarshan Jadcherla.

This multidisciplinary program is one of the only programs in the United States targeted to understanding the mechanisms of developmental gastrointestinal motility and neonatal and infant feeding disorders. Through the understanding of the normal and dysfunctional mechanisms, this knowledge has paved the way for implementing and improving therapeutic approaches in the vulnerable NICU population.

Our team consists of physicians, APNs, nurses, research associates and research assistants.

At the end of the fellowship, fellows will be able to:

  • Understand the normal process of gastrointestinal transit time from mouth to anus
  • Understand the development and maturation of normal physiologic functions including suck and swallow, esophageal transit, gastric emptying, small bowel and colonic transit and defecation
  • Identify the clinical signs and symptoms of gastroesophageal reflux disease, feeding intolerance, aerodigestive disorders, and gastrointestinal dysmotility

What You Need to Know


The Neonatal and Infant Feeding Disorders Program has four areas of focus; clinical, education, quality and research. 

  • Clinical: The Neonatal and Infant Feeding Disorders Clinical Service Program has a unique focus on the diagnosis of gastrointestinal dysmotility biomarkers and mechanisms among high-risk NICU infants. Various studies, such as: esophageal manometry and pH impedance studies are often performed to help develop long term feeding strategies for the primary care team.
  • Education: Through the clinical and translational research that is done by the program, education is able to be brought forth in various aspects. These educational opportunities are presented through avenues like The Feeding Enhancement Program’s educational presentations, weekly feeding rounds and various training sessions for clinical staff.
  • Quality: The Feeding Enhancement Program is the quality improvement program that focuses on accelerating the acquisition of feeding milestones and applying the model in a multi-disciplinary setting to ensure feeding success.
  • Research: From the gracious support of the National Institute of Health, Dr. Jadcherla and his lab staff have been able to explore and give new light to various areas that have an effect on esophageal motility and aerodigestive reflexes in infants. This cutting edge research has been documented in numerous journal publications, conference presentations and a number of book chapters and books.

During the fellowship, trainees will be involved directly with crib-side evaluation of gut motility and aero-digestive pathophysiology in NICU infants. Fellows will be involved with the diagnostic consults that the program receives for infants in the NICU that have feeding issues.

This fellowship will also have a strong focus on research. The fellow will be required to spend at least 50 percent of his/her time involved in research activities under the mentorship of Dr. Sudarshan Jadcherla.
