About

Megan R. Gunnar is a pioneering developmental psychobiologist whose research has fundamentally shaped our understanding of how early stress and caregiving environments influence the developing brain and stress regulation systems. Her key research areas include the neurobiology of stress, early adversity, and the development of the hypothalamic-pituitary-adrenal (HPA) axis in children. Gunnar is best known for her groundbreaking work on the cortisol response in infants and young children, demonstrating that sensitive, supportive caregiving can buffer the stress system from dysregulation. Her highly cited studies, including the prospective longitudinal investigation of infant freezing as a predictor of adolescent internalizing symptoms, have revealed how early behavioral and biological markers—such as prolonged freezing or elevated cortisol—can signal risk for later anxiety and depression. With thousands of citations across her career, Gunnar’s research has had a transformative impact on developmental science, informing interventions for children exposed to neglect, trauma, or institutional care. She is a recipient of numerous awards, including the Distinguished Scientific Contribution Award from the American Psychological Association, and her work continues to guide researchers and clinicians in identifying early risk factors and protective mechanisms in child development.
