Dr. Blatter received his undergraduate degree from Macalester College (St. Paul, Minnesota), and earned his M.D. degree from the University of Pittsburgh School of Medicine (Pittsburgh, Pennsylvania). He did his training in pediatrics at Children’s Hospital of Pittsburgh of UPMC (Pittsburgh, Pennsylvania), where he also completed his fellowship training in pediatric pulmonology. During his fellowship, Dr. Blatter earned a master’s degree in public health at the University of Pittsburgh School of Medicine. His research has focused on elucidating links between environment, genetics, and chronic respiratory disease. He has examined the effect of nutrition, including folate status, on asthma severity. Dr. Blatter has also evaluated the respiratory impact of house dust exposures, including both common allergens and pathogen-associated molecular patterns (PAMPs). In addition, he has studied gene-by-environment interactions in psychosocial stress and asthma, identifying genetic markers that may contribute to stress susceptibility among children with asthma. His work on environment and respiratory disease was supported in part by a training grant from the Cystic Fibrosis Foundation (CFF). Throughout his training, Dr. Blatter has pursued clinical interests in pediatric pulmonary transplant medicine, attending the American Society of Transplantation (AST) Fellows Symposium. He is the Associate Director of the Washington University Pediatric Lung Transplantation Center. His recent research is focused on identifying factors that influence lung transplant outcomes in children.
