Research
Overview
Dr. Gallagher has trained numerous undergraduate, graduate and medical students, MD and PhD postdoctoral fellows, and sabbatical faculty. Laboratory graduates hold positions throughout the world and trainees have
received awards and honors from local, regional, and national organizations. After serving as the PI on the Yale Neonatal/Perinatal Medicine T32 training grant for many years, he now participates in training grants in Genetics, Medicine, and Laboratory Medicine. He serves on the Department of Pediatrics Scholarship Oversight Committee (SOC). He has served on numerous individual SOCs as member or chair, as well as various medical and graduate school mentoring committees, PhD thesis committees, etc.
