I am an associate professor and director of the Weiser Diplomacy Center and International Policy Center at the Gerald R. Ford School of Public Policy, University of Michigan. I am also a faculty affiliate of the University's International Institute.

Much of my current research focuses on international interventions in conflict-torn states, and my new book is entitled Sovereignty Sharing in Fragile States. I also continue to work on international politics in Southeast Asia and the broader Indo-Pacific region. My co-edited volume with Kiyo Tsutsui at Stanford, The Courteous Power: Japan and Southeast Asia in the Indo-Pacific Era, was published recently by the University of Michigan Press.



Sovereignty Sharing in Fragile States

Stanford University Press, 2021

In fragile states, domestic and international actors sometimes take the momentous step of sharing sovereign authority to provide basic public services and build the rule of law. While sovereignty sharing can help address gaps in governance, it is inherently difficult, risking redundancy, confusion over roles, and feuds between partners when their interests diverge. Sovereignty Sharing in Fragile States sheds light on how and why these extraordinary joint ventures are created, designed, and implemented. Based on extensive field research in several countries and more than 150 interviews with senior figures from governments, the UN, donor states, and civil society, the book discusses when sovereignty sharing may be justified and when it is most likely to achieve its aims. It examines a diverse range of sovereignty-sharing arrangements, including hybrid criminal tribunals, joint policing arrangements, and anti-corruption initiatives, in Sierra Leone, Cambodia, Lebanon, Timor-Leste, Guatemala, and Liberia. It provides the first comparative assessment of these remarkable attempts to repair ruptures in the rule of law - the heart of a well-governed state.

The Courteous Power: Japan and Southeast Asia in the Indo-Pacific Era

Co-edited with Kiyoteru Tsutsui, Stanford University

University of Michigan Press, 2021

This book explores Japan's vital role in Southeast Asia before and during the Indo-Pacific era. At a time when many analysts focus on Sino-American competition in the region, the book reveals Japan's profound influence on contemporary Southeast Asian politics, economics, and society through its cultivation of an identity as a courteous power - an influential political actor that uses a guiding hand rather than a clenched fist to pursue its interests.
