For over 13 years, her research has focused on HPV and cervical cancer in HIV-positive individuals, aging women, and in low-resource settings. It has spanned the translational spectrum from epidemiological studies to understand the natural history of the disease, to studying the effectiveness and implementation of cervical cancer prevention in low-resource settings. Dr. Rositch has ongoing research in Baltimore, South America, and across sub-Saharan Africa. Her recent work is focused on leveraging her training in Implementation Science and experience in cervical cancer prevention to identify novel multidisciplinary and multilevel approaches for breast cancer control in low-resource settings. Dr. Rositch's current research program has three main areas: 1) epidemiology and prevention of HPV and invasive cervical cancer in aging and older women; 2) effectiveness and implementation of novel cervical and breast cancer prevention and control programs in high-risk populations and in low-resource settings including Peru, Tanzania, Kenya and South Africa; and 3) cancer and HIV, with a focus on treatment and survival disparities and on defining features of non-AIDS defining cancers in people with HIV/AIDS.
