Narrative icon

  I am PI of the Community Network Program Center funded by NCI, Co-PI of the Southern Community Cohort Study (a landmark epidemiological study) and Director of the Diabetes Research and Training Center (DRTC) Community Outreach and Health Disparities Core at Meharry Medical College. I am also a member of the Vanderbilt-Meharry Community Engaged Research Core (CERC) of the VICTR (CTSA), and was Meharry PI of an administrative supplement to the CERC, related to research capacity building in 3 Nashville coalitions as well as the development of training modules related to community engaged research. I have extensive experience as a behavioral scientist in public health research, with expertise in community engagement, culturally sensitive interventions, quality of care improvements, recruitment and retention of minorities, qualitative methods and analysis, and community-based participatory research. As a nutritional scientist, I bring the knowledge of assessment of dietary and physical activity practices. These projects aim to understand the causes of cancer-and other chronic disease-disparities and to address these disparities by improving primary and secondary prevention practices in African Americans.
