Pediatric GI Nutrition Fellowship | Overview


We welcome your interest in the Harvard Medical School Fellowship in Pediatric Gastroenterology and Nutrition. The fellowship program has been in continuous operation for more than 30 years. It is based at Boston Children's Hospital, a world renowned free-standing pediatric hospital located adjacent to the main campuses of Harvard Medical School and the Harvard School of Public Health.


The opportunities for research and clinical training at Boston Children's Hospital are unparalleled. We have an active faculty of over 60 pediatric gastroenterologists. More than 35,000 patients are seen annually in our ambulatory programs. In addition to busy general teaching clinics, our fellows participate in multi-disciplinary subspecialty programs including our Centers for Inflammatory Bowel Disease, Motility, and Childhood Liver Disease. Our inpatient service provides general and subspecialty care to local, regional, and international patients referred for evaluation and management of the broadest array of developmental and acquired GI disorders. Our fellows receive technical training in our state-of-the-art Gastrointestinal Procedure Unit in which more than 3,000 diagnostic and therapeutic procedures are performed annually.

The goal of our fellowship is to train the future leaders in academic gastroenterology, and we provide the individual mentoring and fellow-specific training to support the interests and career development of each of our trainees. To that end, we have established specialized training programs for individuals interested in pursuing careers as Physician-Scientists and Clinician-Innovators, as well as those seeking advanced training in the management of patients with cystic fibrosis.


We provide all of our fellows with considerable protected academic and career development time during their second and third years of training. Fellows use this mentored time to acquire the skill-sets in basic, clinical, and translational research that will enable them to develop questions and participate in original independent investigation. Senior faculty members are available to assist fellows in their applications for extramural grant support from the NIH and private foundations. Fellows interested in training as Physician-Scientists benefit from the support of our extensive faculty with active research programs in the areas of molecular cell and developmental biology, mucosal immunology, and microbial pathogenesis. In total, we have forty NIH-funded independent investigators on our research faculty, representing an annual research base of over $10,000,000. Fellows interested in developing careers as Clinician-Innovators participate in protocols evaluating novel pharmacologic or diagnostic modalities, outcomes research, and nutritional epidemiology. Clinician-Innovators with an interest in education may choose to pursue training in the development of innovative approaches to medical education, health policy, health-care systems analysis and management, and quality improvement. Fellows interested in advancing our understanding of the management of patients with Cystic Fibrosis and related disorders are provided with additional clinical exposure to the ambulatory and inpatient management of this patient population.


Significant research infrastructure and resources are available to support our fellows through the Harvard Digestive Disease Center, which is directed by our Division Chief, Dr. Wayne Lencer. Additional training and collaborative opportunities are available through the Harvard Catalyst, a Harvard University-sponsored program directed at facilitating the translation of medical discovery into clinical practice. Our fellows benefit tremendously from our close proximity to the resources available at other area research and clinical institutions, and investigators from the Harvard Institutes of Medicine, Howard Hughes Medical Institute, Center for Blood Research, Harvard School of Public Health, Dana-Farber Cancer Institute, Beth Israel Deaconess Medical Center, and Brigham and Women's Hospital are represented on our research faculty.


Our program is centered on the participation of our fellows in directing the content of our curriculum. To this end, fellows are active participants on subcommittees that meet regularly to evaluate individual components of clinical and research training. Initiatives are proposed and actualized, under the oversight of our Fellowship Steering Committee.

We invite you to review our fellowship website, which provides a more comprehensive view of our training program. If after visiting this site, you have specific questions or special interests that require additional information, please feel free to contact myself directly. We welcome your inquiries.

The application and interview process will provide you with an opportunity to visit us and to discuss the program with our clinical and research faculty as well as with our current fellows. We feel that our fellowship represents a truly outstanding training environment. The Boston medical and scientific communities offer numerous possibilities for superb training in basic and clinical research. I hope you consider our fellowship program, and I look forward to having the opportunity to speak with you.
