Background

Make A Gift

Matthew Ladra, M.D., M.P.H., is the director of pediatric radiation oncology for the Johns Hopkins Kimmel Cancer Center, a clinical collaboration with Children’s National Medical Center, where Dr. Ladra serves as faculty in the department of pediatric oncology. He is also an assistant professor of radiation oncology and molecular radiation sciences at the Johns Hopkins School of Medicine. 

Dr. Ladra will lead the Johns Hopkins National Proton Therapy Center’s pediatric program in partnership with Children’s National Medical Center. The center will begin treating pediatric patients in the fall of 2019. Previously, he served as the director of pediatric radiation at the Provision Center for Proton Therapy in Tennessee.  He also completed a 2-year fellowship in pediatric proton therapy at the Massachusetts General Hospital’s Francis H. Burr Proton Center. 

Dr. Ladra is one of a handful of radiation oncologists whose research and clinical efforts focus exclusively on pediatric patients.  He is frequently invited to speak on pediatric radiation oncology topics internationally and across the U.S. and has published extensively on the subject through original research book chapters and review articles.   Dr. Ladra’s research efforts focus mainly on pediatric rhabdomyosarcoma treatment, early phase clinical trials involving radiation and non-chemotherapeutic agents, and reducing neurocognitive toxicity for pediatric brain tumor patients.

He is board certified in radiation oncology by the American Board of Radiology.
