Dr. Mrug is a child clinical psychologist whose main
interests lie in developmental psychopathology. Dr. Mrug’s
current research focuses on individual and contextual
influences in the development of externalizing behavior
problems in children and adolescents, such as aggressive and
disruptive behavior, delinquency, and substance use. Primary
predictors of interest include pubertal timing, exposure to
violence, peer relationships, parental practices, and
broader influences of schools and neighborhoods.
Other areas of interest include peer relationships and
social functioning in children with Attention Deficit
Hyperactivity Disorder (ADHD) and the study of social
cognitions in children, especially as they relate to peer
acceptance and rejection.
