Her research focuses on age and race/ethnicity related disparities in cancer care and outcomes. She has conducted more than a decade of research on issues in access to screening and treatment for breast and cervical cancer among elderly black women. She has also conducted research to demonstrate that mammography continues to save lives for elderly women of all ages, even in the presence of co-existent medical conditions.
She is presently Principal Investigator of the AHCPR-funded PORT evaluating the patterns of care, outcomes, and cost-effectiveness of treatment of early stage disease among newly diagnosed elderly black and white women. She is leading two NIH-funded grants to examine cost-effectiveness of cancer screening in elderly, and elderly African-American women. A major accomplishment of her screening work was the inclusion of triennial Pap smears as the first early detection effort covered for Medicare beneficiaries.
