She is the author of “Trust and Fear in Civil Wars: Ending Intrastate Conflicts,” in which she argues that combatants' perceptions of each other can fuel commitment problems and other fears for future security, prolonging civil wars when information suggests a deal may be especially dangerous. Current research interests include the exploration of the effects of atrocities on war duration and outcomes, the role of cultural discrimination in civil wars, and the influence of commitment problems on strategic choices between violence and nonviolence.
