Jill de Jong, MD, PhD

Assistant Professor of Pediatrics

Associate Director, Fellowship Program

Co-Director, Fellowship Program

Jill de Jong, MD, PhD, treats children with all types of cancers and blood diseases, as well as hematopoietic stem cell transplant patients. She has specialized expertise in: autoimmune blood diseases, such as autoimmune hemolytic anemia, autoimmune neutropenia, immune thrombocytopenia purpura, and Evans syndrome; in addition to hemoglobinopathies, such as thalassemia (alpha, beta, and delta), and bleeding and clotting disorders.

Dr. de Jong's research focuses on hematopoietic stem cells and understanding the genes that can cause leukemia. She is developing novel strategies to discover new regulatory mechanisms that drive normal hematopoietic stem cells, and to understand how those mechanisms can lead to leukemia when they function abnormally. Dr. de Jong’s research is currently funded by the National Institutes of Health. She also has many published research articles and chapter reviews.
