Building on my earlier dissertation research, much of my work in this area explores the psychological mechanisms undergirding the public's political attitudes in the wake of terrorism, examining the role of anger and moral outrage in shaping the mass public's response to this violence. In other research on terrorism, I extend my interests in the strategic and psychological aspects of militancy and terrorism, including projects examining the tactical choices of militant organizations, extremist leaders' strategic rhetoric, and interpersonal processes in radicalization. My new NSF project in this area examines these topics in the context of the modern white nationalist movement.
