About me

Hi, my name is Sam Cheng, MD, MSc, PhD, and I am an associate professor for the department of pediatrics at the University of Florida College of Medicine. I earned my medical degree and master's degree in clinical investigation from Tongji Medical University in China, and then trained in molecular biology and genetics while being a World Health Organization fellow at the Great Ormond Street Hospital/Child Health Institute in London. I also completed my doctoral degree in ion transport physiology and biochemistry at Karolinska Institute in Stockholm, Sweden.

I completed pediatric residencies at Tongji Hospital in Wuhan, China, and at SUNY Downstate Medical Center in Brooklyn, New York. As a postdoctoral fellow at Yale University in Connecticut, I expanded my training in fluids, electrolytes, and nutrition and calcium-sensing receptor physiology and pathology in relation to diarrhea, inflammatory bowel disease and neuro-gastrointestinal diseases in children. I am board-certified in pediatrics and pediatric gastroenterology.

My work and research have resulted in multiple awards, grants, patents and published articles in the Journal of Clinical Investigation, Gastroenterology, the Proceedings of the National Academy of Sciences and the American Journal of Physiology. My current work builds on my prior work and training in combination with my current interests as a GI physiologist and pediatric gastroenterologist. I am particularly interested in pediatric nutrition, inflammatory bowel disease, short bowel syndrome, irritable bowel syndrome and other diarrheal disorders in children. I also help run UF pediatric short bowel clinic and the UF pediatric anorectal manometry program.
