General Program Description

Gastroenterology (GI) fellows accept graduated responsibility in the clinical management of children with gastrointestinal, hepatic and nutritional disorders under the direct supervision of a board certified pediatric gastroenterologist while rotating through the gastroenterology inpatient service and the liver transplant inpatient service. This responsibility includes patient care, parent conferences, consultations with other subspecialties, night and weekend call, and interfacing with the many services that interact with pediatric gastroenterology, nutrition, and liver transplant.

The first year of the fellowship will be primarily clinical in nature, during which the fellow will become trained in the evaluation and management of children with diseases of the gastrointestinal system and their nutritional consequents. During the course of the first year, the trainee will be introduced to the ongoing research programs of each contributing faculty member so that by the end of the year, the GI fellow will be able to select a research area to pursue. The second and third years will be devoted primarily to investigation in the field of Pediatric Gastroenterology and Nutrition, but the GI fellow will continue to participate in the clinical activities of the Division to the appropriate degree to maintain and hone clinical skills. After completion of the fellowship, the GI fellow will have met the requirements for board eligibility in Pediatric Gastroenterology  set forth by the America Board of Pediatrics.

Eligibility and Application Process

Due to NIH grant regulations, to be accepted into our 3-year pediatric GI fellowship program, an applicant must have a green card or be a U.S. citizen. Overseas citizens with a J1 visa can be accepted into our program as long as they are in a U.S. or Canadian residency program and have been for 2 years. We can transfer their J1 visa from the residency program to here. We do not accept H1B visas. In addition, all applicants must be eligible for a California Medical License. Prior to submitting an application, potential fellows should verify that their medical school is on the list of those recognized by the Medical Board of California. Applicants meeting these requirements are considered upon the strength of their test scores, academic achievements, and recommendations.

We participate in the Electronic Residency Application Service (ERAS). Applications for fellowship positions should be submitted through ERAS starting in July one year before anticipated fellowship start date. Interested applicants should apply electronically through ERAS and provide the following documents:

  1. Completed ERAS application
  2. At least two and no more than four letters of reference including one from your residency program director. We recommend at least one letter be written by a faculty member in Pediatric Gastroenterology.
  3. Medical school transcript including Dean's letter
  4. Curriculum Vitae
  5. Personal statement

Applications will be reviewed only once they are complete. Please contact us directly if your application will be delayed for any reason. We do not typically accept applications submitted after our deadline (1st or 2nd Wednesday of September - 9 weeks from ERAS opening).

If selected for interview, applicants will be contacted directly by the program coordinator, and a full day of interviews will be scheduled in August, September, or October, depending upon program and applicant availability.
