Areas of Interest: 

Global health; reproductive, perinatal and child health and development; environmental and lifestyle factors; life-course and reproductive epidemiology; child health disparities; biomarkers in population research; policy impacts.  

I specialise in global reproductive, perinatal and child health, including birth outcomes, neurodevelopment, autism, cognition, and asthma. My work emphasizes the life-course approach, focusing on the early life period as it sets the stage for life long health. My research involves large population studies to examine linkages between prenatal and early life environmental, lifestyle and community factors, and reproductive, childhood and population health. My current research takes place internationally and in California. The overarching aim of my work is creating population based evidence that can impact policies and translate into community based prevention.
