Dr. Matthew Nock completed his clinical internship at the NYU-Child Study Center and Bellevue Hospital Center and joined the faculty of the Department of Psychology at Harvard University the same year. His research interests focus primarily on the etiology, assessment, and treatment of self-injurious and aggressive behaviors, particularly among children and adolescents. Current projects include the development and evaluation of laboratory and ecological assessment methods for evaluating processes associated with self-injurious and aggressive behaviors. A related line of his research focuses on the evaluation of treatments for impulsive, aggressive, and self-injurious behaviors and on factors that mediate and moderate clinical change.
