I was trained as a social psychologist and personality researcher and have become involved in the emerging field of evolutionary psychology. My research primarily consists of a series of studies analyzing the characteristics of men who commit aggression against women, particularly sexual aggression. We have found that for an individual to commit sexually aggressive acts several factors typically converge that may be meaningfully organized into three major statistical “paths.” (i.e., sexual aggressors have relatively high scores on characteristics comprising these “paths”). In several studies we successfully tested an evolutionary-based model based on this theoretical framework. A related aspect of our research program focuses on mass media effects, including sexually explicit media.
