Dr. McCarthy is an epidemiologist and health services researcher with expertise using large administrative databases and national surveys to address healthcare issues. Her primary area of research interest is to investigate disparities in cancer across the continuum of care from secondary prevention to diagnosis, treatment and end of life. She is Principal Investigator of two Research Scholar Grants funded by the American Cancer Society targeted at poor and underserved populations. She is particularly interested in decision-making at the end of life care for the very elderly and patients with advanced cancer, and on how disparities in cancer screening and cancer care affect cancer outcomes in racial/ethnic minorities and other disadvantaged and vulnerable populations. Dr. McCarthy has also published studies describing determinants of mammography use in older women as well as the relationship between regular mammography use and breast cancer outcomes in older women. Dr. McCarthy was the recipient of the 2008 Harvard Medical School Young Mentor Award and the 2012 A. Clifford Barger Award for excellence in mentoring.
