Director of Home Parenteral Nutrition and Nutrition Assessment Laboratory, Center for Nutrition, Boston Children’s Hospital

I am a pediatric gastroenterologist and Director of the HPN Program and Nutrition Assessment Laboratory at Boston Children's Hospital. My clinical duties include focusing on children with complex nutritional problems such as short bowel syndrome. I also perform diagnostic and therapeutic endoscopies in children with general gastrointestinal conditions and short bowel syndrome. I am a part of the clinical nutrition inpatient service, where I oversee a group of trainees and registered dietitians that manage parenteral and enteral nutrition on the wards and intensive care units. I also administer and oversee the nutritional research laboratories at BCH, which includes interpretation of indirect calorimetry, breath testing and other advanced nutritional assessments for patients at the hospital.
I am involved in clinical research endeavors which include serving as the PI on an active trial examining the safety and tolerability of IV fish oil lipid emulsion in a novel population of children undergoing hematopoietic cell transplantation and the co-investigator on a trial exploring the validity of air displacement plethysmography in predicting body composition in patients with intestinal failure. I am also the site PI for STARS: Safety and efficacy of apraglutide in patients with SBS intestinal failure. I am the lead investigator for a quality improvement project studying remote patient monitoring (TytocareTM) in at-risk patients in the home parenteral nutrition program during the COVID-19 pandemic. I am a co-investigator on a clinical trial using the device RELiZORB, a digestive enzyme cartridge to help hydrolyze fats in enteral formula in children with intestinal failure on parenteral nutrition. I am a co-investigator of a multi-center study looking at the effects of teduglutide in short bowel syndrome patients on parenteral nutrition. It is undoubtedly because of the mentorship of Dr. Christopher Duggan that my research and clinical duties have thus far been a success.
In summary, I am a pediatric gastroenterologist with an enthusiasm for pediatric nutritional assessment and lipid metabolism. I feel honored to be able to call Boston Children’s Hospital home and will strive to further advance the field of pediatric nutrition through my research endeavors, clinical work and education.
