Dr. Daniel Klein plans to admit a new graduate student pending approval of funding.

Research Interests:

Dr. Klein is interested in developmental psychopathology and adult psychopathology, particularly mood disorders in children, adolescents, and adults. His research explores the intergenerational transmission of depression; the roles of temperament and emotional reactivity, and early adversity in the development and course of mood disorders; the long-term course and continuity of mood disorders; the classification of mood disorders; comorbidity between depression and other disorders; and the psychotherapeutic and psychopharmacological treatment of depressive disorders.

Current Research:  

Dr. Klein is currently directing a longitudinal study of the role of early temperament and emotional style in the development of later mood and anxiety disorders in a large community sample of children (the Stony Brook Temperament Study). The children were assessed at ages 3, 6, 9, 12, 15, and 18. The age 21 wave of assessments recently started. The study uses multiple measurement strategies to assess potential risk, protective, mediating, and moderating factors in multiple domains, including child emotional reactivity and regulation, psychopathology, psychophysiological and behavioral measures of processing of emotional information; ecological momentary assessment of mood and social interactions; polygenic risk scores, stress and pubertal hormones, parenting, stressful life events and chronic stress, and parental personality and psychopathology. In addition, resting state and task-related functional magnetic resonance imaging (fMRI) measures were collected on a subset of the larger sample. Together with Dr. Roman Kotov (Psychiatry), Dr. Klein is also directing a longitudinal study of a large sample of early adolescent girls who have been followed on six occasions to age 20 (the Adolescent Development of Emotions and Personality Traits study). This project also seeks to identify antecedents of, and pathways to, depressive disorders, and uses many of the same measures as the Stony Brook Temperament Study.
