Dr. Eliot M. Rosen is Professor of Oncology, Biochemistry and Molecular & Cell Biology, and Radiation Medicine and a Member of the Lombardi Comprehensive Cancer Center (LCCC) at Georgetown University Medical Center. He also holds the Gragnani Chair in Oncology and Radiation Biology at the LCCC. Dr. Rosen’s major research interests include the function of the breast and ovarian cancer susceptibility gene BRCA1 in breast cancer prevention and development and role of scatter factor (hepatocyte growth factor)/c-Met in the regulation of susceptibility to apoptosis and chemo/radiosensitivity of breast cancers and other tumor types. Dr. Rosen discovered that BRCA1 inhibits estrogen receptor activity and has been studying the BRCA1: estrogen receptor activity for the past ten or so years. Dr. Rosen is also a clinically trained as a Radiation Oncologist and has many years of experience treating breast cancer patients with radiation therapy. Thus, he has a solid knowledge of the natural history and treatment of this cancer type.
