Expertise: Reproductive Epidemiology, Fetal Programming, Stress, Neurodevelopmental Outcomes
Fetal programming research, particularly stress exposure, maternal nutrition, maternal drug exposure, pre-existing health conditions and other environmental factors; early childhood and neurodevelopmental outcomes.
I specialize in the fields of reproductive, perinatal and child health. My research focuses on exposures during critical periods of fetal development and neurodevelopmental outcomes in the offspring. My research utilizes large Nordic data sources including the Danish National Birth Cohort, a cohort of approximately 100,000 women and their offspring currently in its 11th year of follow-up, and Danish medical registers to establish longitudinal cohorts that span three decades and two generations; as well as databases in California. The overarching goal of my research is to elucidate critical agents and periods during pregnancy that impact health outcomes over the lifespan.
