A clinically integrated network of physicians and providers employed by UChicago Medicine who offer care in inpatient, community, ambulatory, acute care or extended care settings.


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: hematology, including disorders of red blood cells, white blood cells and platelets; autoimmune blood diseases; bleeding and clotting disorders; and genetic (inherited) blood diseases.

Dr. de Jong's research focuses on understanding genetic syndromes that predispose patients to bone marrow failure and/or cancer. By studying known genetic mutations that lead to cancer and uncovering new cancer predisposition syndromes, her work examines the mechanisms that cause cancer in order to improve cancer therapies. Through her research, she aims to optimize early detection, treatment, and, ultimately, prevention of cancer and bone marrow disorders.
