Lab: Aggression and Intergroup Relations Lab website


My research is primarily focused on factors that impact aggressive behavior and violence. I am interested in a variety of personality factors including trait rumination, narcissism, impulsivity, attachment style, and religiosity. I have also investigated a variety of situational factors that impact aggression including rumination, social support, power restoration, alcohol priming, and drug use. A related line of research investigates the impact of trait displaced aggression on romantic relationships, life satisfaction, and both mental and physical health. Finally, I have smaller research programs in the areas of both intergroup relations and evolutionary psychology (specifically gender differences in mating strategies).  See the Aggression and Intergroup Relations Lab website for more details.
