Research interests, include: Probiotics and studying the gut micro biome. Ongoing research studies, include: 1. Studies to investigate the role of gut micro biome in a number of pediatric disorders. 2. Studying the effect of probiotics and how they modify the gut microbiota. 3. NIH-funding to study the effect of probiotics on children with irritable bowel syndrome and how probiotics modify gut micro biota.
