 Governing Security after Civil War: The Politics of Institutional Change in the Security Sector
Oxford University Press, 2022

Military and police forces are central to the onset of civil war, and to the sustainability of post-conflict peace.  Security assistance is one of the largest components of international stabilization and peacebuilding efforts.  Yet we know little about why efforts to restructure security forces succeed or fail.  My book examines decisions to politicize or professionalize security forces in the aftermath of civil war, focusing on elites’ political calculations as they seek to build and maintain their authority.  I show how the constraints that stem from their political networks and revenue sources affect key decisions that shape the composition of the security forces, their relationship to civilian authority, and their adherence to the rule of law.   The book draws upon in-depth field research in Liberia, Sierra Leone, Bosnia and Herzegovina, and East Timor, an original quantitative dataset of postwar civil-military relations around the world, and mini-case studies of Iraq, Afghanistan, Somalia, and South Sudan.

​In related work, I explore the effects of civil-military relations on the risk of renewed civil war; the interaction of security assistance and domestic politics on civil-military relations in postwar Sierra Leone and Liberia; the effects of security assistance on civil-military relations; the effects of UN Peacekeeping on security sector reform, and the impact of foreign aid on state effectiveness after civil war.  

The Politics of Policing, Organized Crime, and Conflict

Transnational organized crime has become a growing threat to human livelihoods and economies. In many settings, organized crime and conflict overlap and interact to fuel high levels of violence. Criminal and insurgent groups often play political roles, as politicians rely on them to mobilize voters; citizens turn to them for protection; and criminal groups seek public legitimacy to control territory and markets.  These interactions  lead to distinct forms and levels of violence.  They also affect state responses through policing, which can either escalate violence or mitigate it.  This research program examines how local and transnational politics shape these interconnected forms of organized violence and how they affect state responses through policing.  In an article with anthropologist Marlon Carranza,  we examine varying homicide rates across neighborhoods in three of the most violent cities in northern Honduras.  Based on ethnographic research and comparisons across neighborhoods, we explore how community ties affect the level of violence by mediating the effects of competition between criminal groups and interactions with state officials.  In follow-on research, I explore how interactions between criminal groups and politicians fuel violence around efforts to mobilize political support and compete in elections.

Through ongoing research in Colombia, I am examining how police responses to organized violence reflect the interaction of local politics, armed group presence, and organized crime.   Through public opinion surveys and analysis of municipal data, I am exploring how policing reflects local political pressures , how armed groups and illicit markets affect police tactics, and how these dynamics contribute to violence at the local level.​

Justice and Security in Conflict-Affected Settings

International development programs aimed at promoting justice, security, and the rule of law have struggled to achieve sustained impact.  By examining justice and security as political outcomes rather than technical systems, my research explores the political pressures that have shaped judicial, law enforcement and security systems in developing countries, and that subvert the effects of international development programs.   In several articles and policy reports, I trace how leaders’ political calculations affect their priorities for security and justice and the impact of donor-funded reform efforts.  In a series of articles with Deborah Isser and Doug Porter at the World Bank, we explore alternatives for development practitioners to take these dynamics into account in their work.
