Overview
Developmental epidemiology seeks to apply developmental and epidemiological principles to the study of psychopathology. Within this overall framework, my main research interests relate to the study of depression, anxiety, and disruptive behavior disorders and their effects on service use in children and adolescents. Current activities include studies of (1) relationships among pubertal hormonal changes, morphological changes, life strain, and psychopathology; (2) the development of measures of psychopathology and their links with psychiatric nosology (at the levels of symptoms, diagnoses, and disability); (3) parental burden and service use resulting from child and adolescent psychopathology; (4) comorbidity among psychiatric disorders; (5) factors affecting mental health service use; and (7) psychological predictors of risk for cardiovascular disorders in adolescence.
