Research Statement
Dr. Bellamy's research interests are focused on the methodological issues related to the design and analysis of cluster-randomized trials. She is particularly interested in applying this methodology to community-based research projects and to projects which address health disparities for a variety of clinical and behavioral health outcomes. Currently, her collaborative projects include studies of women's reproductive health, HIV behavioral risk reduction for African Americans, as well as mental health issues of the elderly.
Courses Taught
EPID 623, Applied Survival Analysis
