About Harland Winter, MD

My first academic position was at Boston Children’s Hospital, as the director of the endoscopy and motility units, serving concurrently, during the AIDS epidemic, as the chief of pediatric gastroenterology and nutrition at Boston City Hospital. I joined the faculty at MGH, initially as the director of pediatric endoscopy and now serve as the director of the inflammatory bowel disease program. I have been an active investigator and educator in the fields of pediatric AIDS, gastroesophageal reflux disease and inflammatory bowel disease and serve on scientific advisory boards of the Pediatric AIDS Foundation, the American Liver Foundation and the American Hirschsprung Disease Association, as well as on an NIH Advisory Group, and the Board of Trustees of the Crohn’s and Colitis Foundation of America. In 1995, I was the recipient of the Humanitarian of the Year Award from the Crohn’s and Colitis Foundation and the Excellence in Treatment Guided Research Award from the Autism Society of America. I cofounded the Pediatric IBD Consortium that published many studies supported by three NIH grants and industry.

During 1998-2000, I was elected President of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition and organized the first World Congress of Pediatric Gastroenterology, Hepatology and Nutrition in Boston in 2000. I also initiated the creation of the Children’s Digestive Health and Nutrition Foundation that has raised funds to support educational and research programs focused on the needs of children with gastrointestinal disease.

In 2016, I was the 10th recipient of The Harvard Medical School Lifetime Achievement Award for Community Service for work over 30 years with children and adults with disabilities.

My scientific achievements include the discovery in 2012 of a new disorder (a mutation in the DGAT1 gene), that is found primarily in infants of Ashkenazi Jewish ancestry. The infants present with a serious type of diarrhea, which if not treated in the first week of life, may result in death. If treated with a simple fat-restricted diet, they grow normally. Additionally, I have completed many clinical trials in ulcerative colitis and Crohn’s disease to determine the best treatment options for children. I have worked with the FDA and the European Medicines Agency to advocate for expediting approval of medications used to treat children with Crohn’s disease and ulcerative colitis.
