I have spent my entire academic career at the University of Oregon dating from 1967. My research career has focused on school-related behavior disorders among children and youth. My areas of research interest and expertise include universal screening, early intervention, school safety, antisocial behavior in youth, social skills, and delinquency.

I am the lead author and developer of the Systematic Screening for Behavior Disorders Procedure and the First Step Early Intervention Program. Both products have been the focus of numerous federally funded research grants.

I served as Director of the Center on Human Development for 26 years. I am the founder and co-director of the Institute on Violence and Destructive Behavior. I served as Associate Dean for Special Education and Rehabilitation for 14 years. In addition, I’ve served on numerous commissions and taskforces inside and outside the U of O.
