Research Interests
My primary research focus is the role of stress and early trauma in the etiology and ongoing pathology of major depression in adolescence and adulthood. My current work focuses on neurohormonal, social cognitive, and motivational/reward factors that increase the sensitivity to, and generation of, stress in major depression.
