About Me

Abbey studies two broad areas, primarily in Colombia and Latin America. The first is the dynamics of civil war violence, especially when and where armed groups displace civilians, armed group recruitment and defection, and civilian resettlement patterns.  The second is state-building, such as how political institutions like taxation emerge or are imposed by states and armed groups.
