Dr. Mignon Loh, chief of pediatric hematology and oncology, is a cancer specialist who focuses on caring for children with leukemia.

The mission of Loh's research is to bring new laboratory discoveries on pediatric leukemia into the clinic, to ensure that children with the condition receive the most appropriate therapies. Specifically, she investigates better ways to diagnose or treat the disease, as well as ways to predict how an individual patient’s illness will progress.

Loh earned her medical degree at Columbia University. She completed a residency in pediatrics at Boston Children's Hospital and a fellowship in pediatric hematology and oncology at Brigham and Women's Hospital. During her time in Boston, she served as an instructor at Harvard Medical School and as a research fellow at Brigham and Women's Hospital.

For the international research organization Children's Oncology Group, Loh chairs a committee on acute lymphoblastic leukemia (ALL) and is responsible for developing the clinical trial portfolio for newly diagnosed and relapsed patients with the condition. She supervises a highly productive committee and since July 2019 has opened three trials to investigate questions about new immunologic treatments for ALL in children, adolescents and young adults.
