Dr. Julie Jaffray is a board-certified pediatric hematologist/oncologist at Rady Children's Hospital-San Diego and a clinical assistant professor in the Department of Pediatrics at UC San Diego. Her passion is caring for children and adolescents with blood disorders, including bleeding disorders and clotting disorders.

Dr. Jaffray received her medical degree from Flinders University of South Australia. She completed her pediatric residency at the University of Massachusetts School of Medicine and her pediatric hematology/oncology fellowship at Memorial Sloan Kettering Cancer Center/New York Presbyterian Weill Cornell. This was followed by two additional years of training as a hemostasis and thrombosis specialty fellow at Children’s Hospital Los Angeles, where she later became the thrombosis program director and associate clinical director of hematology.

Her research is focused on identifying risk factors that cause blood clots in children and determining the best way to prevent blood clots. Dr. Jaffray leads a 45-institution, national consortium dedicated to preventing and treating blood clots in children, called the CHAT Consortium. Her other passion is caring for adolescent females and girls with heavy menstrual periods and bleeding disorders.
Dr. Jaffray’s work is currently funded by the National Institutes of Health, with past funding from the Hemostasis and Thrombosis Research Society.

Outside of work, she enjoys spending time with her husband, two young daughters and their Bernese Mountain Dog, Sally.
