Summary

Michael Grunstein, MD, PhD is a specialist in pediatric pulmonology. He completed his PhD and medical degrees at McGill University Faculty of Medicine, followed by a residency in Pediatrics at the University of Colorado, and a fellowship in Pulmonary Disease at the University of California, San Francisco. Dr. Grunstein has held faculty positions including Professor of Pediatrics at the University of Pennsylvania School of Medicine and Chief of Pulmonary Medicine at Children's Hospital of Philadelphia. He has published extensively on research in asthma pathogenesis, with emphasis on signaling mechanisms in airway smooth muscle, contributing significantly to the field. He received the Richard Farr Award for his contributions to the application of basic science to allergic diseases and has been an invited speaker widely on related topics in pulmonary medicine and pathobiology. He is currently Professor Emeritus at the Perelman School of Medicine at University of Pennsylvania, and lives in Studio City, CA.
