Dr. Treleaven studies the mechanisms through which family and community context shape health and health disparities in early childhood, and how health system characteristics affect children’s health and healthcare utilization. This includes how families make decisions and investments related to young children’s health, with particular interests in economic insecurity, migration, and gender. She also evaluates interventions related to maternal, newborn, and child health. Across her work, Dr. Treleaven is interested in developing and testing innovative survey measures and strategies to improve measurement of health and mortality in early childhood.
