Dr. Gallagher’s research focuses on normal and perturbed hematopoiesis. His primary focus is the genetic basis of inherited disorders of hematopoiesis, with a special interest in disorders of the erythrocyte the erythrocyte and the molecular control of erythropoiesis. Dr. Gallagher’s research is funded by the NIH and private foundations. Dr. Gallagher is co-director of the Yale Cooperative Center for Excellence in Hematology. Dr. Gallagher is fully engaged in the Yale scientific community, with joint appointments in Pathology and Genetics, and active membership in the Yale Stem Cell Center. He is director of the Yale Center for Blood Disorders. Current extramural activities include Editorial Board service for the American Journal of Hematology, Pediatric and Developmental Pathology, BMC Pregnancy and Childbirth (Associate Editor), Frontiers in Physiology, and Blood Cells, Molecules and Disease and grant and abstract reviewing for numerous NIH, private foundations, and academic society meetings including PAS. He has served as chair of the NIH Erythrocyte and Leukocyte Biology Study Section (now MCH) and as chair of the American Society of Hematology Scientific Subcommittee on Hemoglobin/Red Cell.
Specialized Terms: Neonatal hematology; Erythropoiesis; Inherited abnormalities of the erythrocyte including metabolic, membrane, and hemoglobin disorders; Sickle cell disease; Hereditary spherocytosis; Elliptocytosis; Pyropoikilocytosis; Stomatocytosis.
Extensive Research Description
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. In addition to serving as the PI on the Yale Neonatal/Perinatal Medicine T32 training grant, he participates in training grants in Genetics, Pathology and Medicine.
