Dr. Heymach received his MD and PhD degrees from Stanford. He completed his internship and residency in internal medicine at Brigham and Women’s Hospital and his medical oncology fellowship at Dana-Farber/Partners HealthCare. He joined the faculty at MD Anderson Cancer Center, becoming chair of the Thoracic/Head and Neck Medical Oncology Department. He currently holds the David Bruton Jr. chair in cancer research. Advances from his laboratory include the discovery of new therapeutic targets for small cell lung cancer; identification of new biomarkers and mechanisms of resistance to VEGF and EGFR inhibitors; and the recent recognition that KRAS-mutant lung cancers can be divided into biologically distinct subgroups based on genomic profiles, and that these subgroups predict response to immunotherapy and other treatments.
