I trained in Gastroenterology and Nutrition then I returned to the practice of General Pediatrics and retained an interest in non-procedural gastroenterology. This suits my many interests. 

Within general pediatrics, my interests include becoming an expert diagnostician, and optmizing the health outcomes for children who come for well child visits. I am also interested in mastering and teaching the physical examination of children. More recently I have become interested in oral health, mental health in primary care, and performance improvement activities.  

Within my subspecialty, I am primarily interested in nutrition, growth, lipid disorders, cardiovascular health, the use of statin medications in children, and the use of infant formula.

I have been a panel member of the FDA's Office of Orphan Product Development and I also act as a reviewer for all 3 major Pediatric journals, Pediatrics, JAMA pediatrics, and the Journal of Pediatrics.  I am and Editorial Board member for the AAP publication, Pediatrics in Review.  

I teach pediatric residents and medical students several times a week. This is a source of deep and increasing satisfaction for me.

While being a physician is intellectually satisfying I view it fundamentally as a job of service to patients, students, resident trainees, and to my superb peers here.
