Her primary research interests are in the identification of genetic and molecular factors influencing risk of cancer and factors associated with prognosis and treatment outcomes. Her research focuses on breast, lung, and ovarian cancers, as well as the role of microRNAs in cancer detection, risk and prognosis. Current projects include the identification of inherited genetic variation influencing susceptibility to cancer, and plasma microRNA expression in breast cancer detection and prognosis, as well as lung cancer detection.
