I am a molecular epidemiologist whose research focuses on both the etiology of breast cancer and factors that influence treatment outcomes, including toxicities experienced with cancer treatment and cancer survival. My etiologic research focuses primarily on breast cancer disparities and I lead a program investigating genetic and non-genetic factors related to aggressive breast cancer in Black women. For a number of years, I have also been conducting research to understand how lifestyle factors, as well as genetics and tumor characteristics, are associated with treatment outcomes.

I have served as a standing member of the NCI study section related to cancer epidemiology and continue to serve ad hoc on a number of NCI study sections. I was a member of the Board of Scientific Advisors to the Director of the NCI and serve on a number of scientific advisory boards. To date, I have more than 440 publications in peer-reviewed journals, with an h-index of 97.
