Meet a PennMedicine Researcher

Yaël P. Mossé, MD

Yaël P. Mossé, MD
Professor of Pediatrics: Oncology, is the recipient of the 2024 William Osler Patient Oriented Research Award. Established in 1996 to honor Dr. Osler, a “Father of Clinical Medicine” who, in the 1880s at the School of Medicine, revolutionized clinical teaching research, the Osler Award recognizes achievement for research in which an investigator directly interacts with human subjects. Dr. Yaël Mossé is a distinguished physician-scientist whose groundbreaking research on ALK oncogene mutations has transformed the landscape of pediatric oncology, directly enhancing the treatment and outcomes for children with neuroblastoma and other solid tumors. Her work harnessing targeted protein degradation approaches will directly target five essential oncoproteins that drive the growth of childhood solid tumors. As the leader of the Neuroblastoma Developmental Therapeutics Program at CHOP, she fosters collaboration across disciplines to translate genomic discoveries into clinical practice, providing hope and innovative therapies for vulnerable patients from around the world.
