Personal profile

Research Interests

I completed my fellowship at the Combined Program in Pediatric Gastroenterology at Harvard Medical School. I then join the faculty at Children's Hospital Boston and Harvard Medical School and continued a research fellowship in the laboratory of Dr. Stephen Galli at the Beth Israel Deaconess Medical Center. In 2000, I joined the faculty at the SUNY Downstate as the Vice-Chairman of Research and Education, and then in 2003 became the Division Director for Pediatric GI at the Children's Hospital at Montefiore and Albert Einstein College of Medicine. In 2008, I joined the faculty at Feinberg and Lurie Children's Hospital as the Chief of Gastroenterology, Hepatology, and Nutrition

My laboratory has a longstanding interest in mast cell and eosinophil biology. We have developed specific and novel in vivo approaches for the analysis of mast cell function in experimental gastrointestinal inflammatory and allergic reactions. We can apply this model to determine the precise influence of mast cells and mast cell-derived cytokines/chemokines in gastrointestinal inflammation.

My clinical research interest is eosinophilic esophagitis and involves efforts to improve the diagnostic and treatment options for patients
