Current Research Studies

Dr. Farrah Lazare is one of our pediatric gastroenterologists, Director of our Nutrition program, as well as Assistant Professor of Pediatrics at the University of Stony Brook. She is currently involved in researching both cow’s milk protein intolerance as well as breast milk protein intolerance. She published a paper in JPGN in 2014 regarding the rapid resolution of cow’s milk protein intolerance in infants. She is currently researching elimination of dairy in a mother’s diet and its effects in breast fed infants. Dr. Lazare runs the screenings for all patients in the CHANGE weight loss program and is actively involved in Team Based Learning (TBL) with the medical students.

Louisa Ferrara, board certified specialist in pediatric feeding and swallowing disorders,  acts as an active investigator in the field of pediatric swallowing disorders. She has completed two research studies assessing the swallowing mechanism in preterm and ill, full term infants. Her focus is on administering Video Fluoroscopic Swallow Studies to ensure that these at risk population of infants are orally feeding with maximal safety and efficiency. Her future research endeavors include investigating the efficacy of various feeding modifications and early feeding milestone acquisition.
