Philosophy of Care 

My interest in pediatric gastroenterology and nutrition was driven by formative experiences in medical school and residency where I saw how important nutritional interventions can be to improve maternal and child health.  My work in Tanzania, India and other countries informs the care of my patients in Boston, both scientifically and philosophically.  Diseases that are easily prevented in the US by clean water, good food and vaccines unfortunately still plague many of the world’s children, and by studying better interventions among children with diarrhea, we can improve medical and nutritional outcomes for all.  I enjoy working in the collaborative, multidisciplinary environment that the field of nutrition engenders, and have the privilege of working with excellent physicians, nurses, dieticians and research staff in many settings.

Christopher Duggan, M.D., M.P.H. is a pediatric gastroenterologist and nutrition physician at Boston Children's Hospital where he directs the Center for Nutrition. He is Medical Director of the Center for Advanced Intestinal Rehabilitation, one of the largest centers in the US for the care of children with intestinal failure/chronic diarrhea syndrome.

His clinical activities focus on optimizing outcomes for children with diarrheal diseases and nutritional problems.  In the US, these include children with intestinal failure (short bowel syndrome), as well as children with critical illness, cancer, HIV infection, cystic fibrosis and other conditions.  In a variety of low and middle income countries, he and colleagues are evaluating the role of micronutrient supplementation in reducing diarrhea and other infectious and nutritional illnesses in mothers and children. Recent studies include the development of new biomarkers of environmental enteric dysfunction, as well as the evaluation of nutritional status on neurodevelopment.

He is course co-director of the Bangalore, Boston Nutrition Collaborative. He is also the course co-director of the Harvard College course “Nutrition and Global Health” and mentors undergraduate, graduate and post-doctoral students at Harvard Medical School and the Harvard TH Chan School of Public Health.
