I am a reproductive, perinatal and pediatric epidemiologist with cross-cutting expertise in infectious disease epidemiology and global health. I have been actively involved in multi-disciplinary 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.

I am a Co-lead of the Healthy Environments and Strong Bodies working group of The Pittsburgh Study (TPS), a community-partnered study designed to understand and promote child and adolescent health and thriving among school-aged children and adolescents from six cohorts spanning from pregnancy through adolescence in Allegheny County. Our working group aims to develop, test and implement interventions that can improve family and child environment and health, address environmental and health inequities and support thriving of all children and youth in our communities. I am committed to examining disparities in pregnancy and child outcomes globally, and I also co-lead the Longitudinal Indian Family hEalth (LIFE) Study, conducted in collaboration between the University of Pittsburgh, the MediCiti Institute of Medical Sciences (MIMS) and Science Health Allied Research & Education (SHARE) INDIA. We are examining the environmental, infectious, lifestyle, metabolic and genetic factors that impact birth outcomes and early childhood health and development among a large cohort of Indian participants that were recruited preconception and followed through conception, pregnancy and delivery.
