Scientific Advisors
Lawrence A. Loeb MD PhD
Co-founder, Scientific Advisor
Dr. Loeb’s research for more than 60 years has focused on human cancer. He is a scientific visionary, best known for the concept of a mutator phenotype in cancer, which is the principle that tumors form and evolve resistance to therapy by virtue of their tendency to acquire mutations at an accelerated rate. He has published extensively in the fields of molecular biology, biochemistry, fidelity of DNA replication, creation of artificial enzymes, and Duplex Sequencing. Dr. Loeb graduated from The City College of New York, received an MD degree from New York University, a Post-Doctoral fellowship at NIH, and a PhD from The University of California Berkeley. He is a professor in the Departments of Pathology and Biochemistry at the University of Washington where he served as director of the MD/PHD program for 23 years.

His clinical Molecular Oncology Lab provides the molecular diagnostic support for many institutional, US Intergroup, international, and pharmaceutical trials. Some of his major scientific contributions over the past three decades include being among the first to document the prevalence and significance of mutations in the Ras/MAPK signaling pathway in acute myeloid leukemia and recognition of the importance of measurable residual disease in ALL, AML and CML. He was awarded the International CML Foundation Award in 2017 and the Washington Global Health Alliance Partnership Award in 2019 for his lab’s work on diagnosing and monitoring chronic myeloid leukemia (CML) in the developing world. A mere subset of his many past and present leadership roles include: Chair of the Leukemia Translational Medicine Committee of the Southwest Oncology Group, Inaugural Chair of the National Cancer Institute and National Institute of Health Leukemia Steering Committee, past member of the Board of Scientific Counselors of the NIH Genome Research Institute, past-chair of the CML Committee of the National Comprehensive Cancer Network and current member of the European Leukemia Network CML committee.
