Christopher S Hourigan

Christopher Hourigan is a physician-scientist known for work on measurable residual disease (MRD; previously termed minimal residual disease) in acute myeloid leukemia.

He was previously Chief of the Laboratory of Myeloid Malignancies at the National Heart, Lung, and Blood Institute and founding co-director of the Myeloid Malignancies Program at the National Institutes of Health in Bethesda, Maryland.

Education Hourigan graduated from Oxford University Medical School and received his DPhil for work with Sir John Bell (physician) at the Weatherall Institute of Molecular Medicine at Oxford University. He completed postdoctoral clinical training at Guy's and St Thomas' Hospital in London, Johns Hopkins Bayview Medical Center, and the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Hospital in Baltimore. that low-level TP53 mutations are detectable pre-transplantation in patients with sickle cell disease who develop myeloid malignancy after hematopoietic stem cell transplantation, and that patient-personalized single cell sequencing can distinguish mutations associated with non-malignant cells rather than residual AML. He has held senior leadership positions in the European Leukemia Network (ELN) guidelines committee for AML MRD, the Foundation for the National Institutes of Health (FNIH) biomarkers consortium for AML MRD, the National Cancer Institute (NCI) MyeloMATCH precision medicine initiative, the Center for International Blood and Marrow Transplant Research (CIBMTR), and on the American Society of Hematology (ASH) guidelines committee for AML in older adults.

Honors and awards In 2019, Hourigan received a Presidential Early Career Award for Scientists and Engineers for his research on Measurable Residual Disease in Acute Myeloid Leukemia.

In 2020, Hourigan was awarded the National Heart, Lung, and Blood Institute Orloff Award and honored for one of the top NIH accomplishments of 2020.
