An internationally recognized cancer geneticist and oncologist, Stephen Gruber, M.D., Ph.D., M.P.H., is a physician-scientist who focuses his clinical practice and research program on precision medicine and the genomics of cancer in order to improve treatment and care for cancer patients and their families. Dr. Gruber is an expert in Lynch syndrome and hereditary susceptibility to colorectal cancer, and he has broad experience in the care of patients and families with inherited susceptibility to cancer.
 
Dr. Gruber leads the Center for Precision Medicine at City of Hope. Precision medicine uses genomic-driven insights, clinical expertise, and advanced analytics to pioneer personalized prevention and treatment plans to transform the outcomes and quality of life for patients, their families and the community. His research program focuses on the genetic epidemiology of cancer, with an emphasis on colorectal cancer, melanoma and other solid tumors, bringing clinical cancer genetics and translational research to cancer prevention.
 
Dr. Gruber earned his Master of Public Health and Ph.D. in epidemiology from Yale University. He earned his medical degree and completed his residency in internal medicine at the University of Pennsylvania and completed fellowships in medical oncology at Johns Hopkins and in clinical medical genetics at University of Michigan. Dr. Gruber has been continuously funded by the National Institutes of Health since 1998 and is an elected member of the American Society of Clinical Investigation.
