For almost two decades, she has been conducting basic and applied research examining the nature, developmental course, predictors and consequences of intimate partner violence. Her interests are broad and comprehensive: she is interested in (a) both low-level aggression and battering violence, (b) in the context of aggression enacted by both men and women, (c) in the related trajectories and consequences of verbal, psychological/ emotional, physical and sexual aggression, and (d) in the impact of violence on perpetrators, victims, relationships, and children. Erika is in the process of developing a primary prevention program targeting intimate partner violence in young adults, and is revising the standard Batterers Education Program used across the state of Iowa.
