Clements Center for Southwest Studies as its director and as associate professor in the Clements Department of History.  He received his PhD in history from Princeton University and was the Clements Research Fellow for the Study of Southwestern America in 2004-2005.  Graybill is a historian of the North American West, with particular interest in expansion, borders, race, violence, and the environment.  His first book, Policing the Great Plains: Rangers, Mounties, and the North American Frontier, 1875-1910 (University of Nebraska Press, 2007), is a comparative study of the two most famous constabularies in the world and pays particular attention to the consequences of frontier absorption for rural people. He co-edited with Benjamin H. Johnson  Bridging National Borders in North America: Transnational and Comparative Histories (Duke University Press, 2010)  which marks the first attempt to bring scholars of both the continent’s border regions into sustained conversation. Graybill wrote the introduction to the reprint of Ruth Allen’s Chapters in the History of Organized Labor in Texas (William P. Clements Center for Southwest Studies, 2006).  Graybill's numerous book chapters and scholarly articles include, "Helen P. Clarke in 'the Age of Tribes':  Montana's Changing Racial landscape, 1870-1920" in Montana: The Magazine of Western History (Spring 2011: 3-19).  He comes to SMU after eight years at the University of Nebraska –Lincoln where he was associate professor of history and director of the Interdisciplinary Program in Nineteenth-Century Studies.  At present, Graybill is finishing his book manuscript, A Mixture of So Many Bloods: A Family Saga of the American West (under contract with W. W. Norton & Co.), about a Montana family of mixed native-white ancestry and the changing notions of racial identity in the West between 1850-1950.
