Personal Statement

As a reproductive, perinatal and pediatric epidemiologist, the overall goal of my work is to improve health, prevent disease and eliminate health disparities among reproductive-aged women and their children.  I have been actively involved in women’s health research for nearly two decades, leading numerous NIH and CDC funded studies that combine reproductive, infectious disease and molecular epidemiology.  Several of my ongoing projects are focused on the role of the vaginal microbiome in pelvic inflammatory disease, infertility and adverse pregnancy outcomes.
