Hanna Stevens runs the Psychiatry and Early Neurobiological Development Lab (PENDL) at the University of Iowa Carver College of Medicine. Her research seeks to understand molecular and cellular aspects of early brain development and their relevance to psychiatric disorders. Her work is particularly focused on understanding how prenatal stress, environmental exposures and genes that play a role in early development have an impact on childhood behavior and act as risk factors for multiple psychiatric disorders. Our goal is to advance mental health diagnosis and treatment of disorders across the lifespan. We particularly focus on the high risk times of pregnancy and early development.
