My research focuses on ethnic, racial, and religious boundary processes, gender, high-risk mobilization, and the causes and consequences of violence. These interests are reflected in my current book project as well as my published papers and ongoing research. I examine three aspects of decision-making in violent contexts in these works. First, I study wartime defection, or how people shift stances from support for state violence to resistance and saving behaviors within the same violent episode. Second, I investigate the relationship between social boundaries and political behaviors, with a specific interest in how racial, ethnic, and religious cleavages inform and are transformed by extreme violence such as genocide. Third, I analyze the role of gender in politically violent movements. Here, I focus on how gender informs individual’s decisions to support and participate in war, and how gender is implicated in movement's decisions to adopt violent tactics.
