Professional Interests

My current research focuses on effectiveness, dissemination, and practice research and the factors that facilitate or inhibit the adoption of effective preventive or clinical practices for children and adolescents.  Particular emphasis is placed on identifying opportunities outside of psychiatric settings for reducing the incidence, prevalence, and disability associated with common mental disorders.
