The central focus of my work is to understand the interplay between social environments and biology to answer the question of how adversity ‘gets under the skin’ to shape mental health during childhood and adolescence. My research examines interplay across multiple levels of responses including emotional, behavioral, genetic, and biological contributions to understanding stress and development. My current work focuses on the stress response system (e.g., the hypothalamic-pituitary-adrenal axis) and the epigenome.
My research broadly focuses on risky family environments for understanding how early adversity shapes developmental trajectories of health and wellbeing across the life course. My work has examined a diverse range of stressors for families and children including, conflict, harsh parenting, neglect, and poverty. I am also interested in the role of family protective factors that buffer against chronic stress and promote more optimal development.
