Associate Professor of Epidemiology
Racial and socioeconomic disparities in the incidence and mortality of various forms of cancer continue to be strong in the United States. The same is true for many other chronic diseases as well as premature mortality. The main focus of my research concerns unraveling the many yet-to-be-identified contributors to these disparities.
I am currently Principal Investigator of the Southern Community Cohort Study (SCCS), a large, NCI-funded prospective cohort study of over 85,000 residents of the southeastern US. Most of my work is based within this cohort. I have particular interests in engaging underserved populations in research and in the effects of vitamin D, nutrition, chronic infections, stress, and socioeconomic deprivation on cancer risk. I believe the microbiome also holds significant promise in addressing unanswered questions about cancer risk and possibly cancer disparities and am working towards assessing methods for collecting (and using stored frozen) biological specimens for microbiome profiling within cohort studies.
I also have strong interests in issues related to reproductive health and have conducted investigations on various types of adverse pregnancy outcomes among childhood cancer survivors in relation to chemotherapy and organ-specific radiotherapy doses they received in their past.
