Areas of Interest:
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 children were assessed at ages 3, 6, and 9; assessments at age 12 and 15 are currently being planned. The study uses multiple measurement strategies to assess potential risk, protective, mediating, and moderating factors in multiple domains, including child emotional reactivity and regulation, executive functioning, psychopathology, psychophysiological and behavioral measures of biases in processing emotional information, susceptibility genes, stress and pubertal hormones, parenting, environmental and family stress, and parental personality and psychopathology. In addition, resting state and task-related functional magnetic resonance imaging (fMRI) measures are being collected on a subset of the larger sample

Dr. Klein is also continuing to work with data sets from several past studies, including several multi-site clinical trials of the treatment of chronically depressed adults; a family and follow-up study of chronically depressed adult outpatients; and a family and follow-up study of a large community sample of adolescents.

Dr. Klein is planning to take a student for Fall, 2015.
