My research program focuses on identifying sociocultural, psychological, and environmental determinants of cancer prevention and control, translating this information into interventions, and disseminating efficacious strategies into clinical and community settings. My research has made several seminal contributions to the fields of cancer control, minority health, and health disparities. For instance, the availability of genetic testing for mutations in cancer susceptibility genes is one of the most important scientific discoveries of the 20th century and has fundamentally changed the way in which early detection is conceptualized and practiced in the US healthcare system. African Americans typically have limited access to genetic counseling and testing for BRCA1 and BRCA2 (BRCA1/2) mutations, and the quality of service has significant limitations in this population. My research developed and evaluated a comprehensive model of how to translate genetic risk information into racially diverse populations. With completion of the first prospective randomized trial to evaluate the effects of culturally tailored versus standard genetic counseling on genetic test acceptance and psychological outcomes, this research established the evidence-base for increasing access to genetic counseling and testing for BRCA1/2 mutations in African American women. My research also was the first to evaluate the long-term effects of genetic testing for BRCA1/2 mutations in racially diverse women. Currently, I am examining community-based strategies for increasing access to, and the enhancing the quality of, cancer control among medically underserved populations. With funding from the NCI and AHRQ, my research is evaluating the effects of community-based navigation for cancer control.
