Ryan Grauer is an Assistant Professor of International Affairs at GSPIA. His research interests center on the sources, uses, and effects of military power in the international system.

Professor Grauer’s current work examines several facets of military organizational behavior and their implications for the generation of combat power. Foremost in this line of research Commanding Military Power (Cambridge, 2016), which examines the way in which armed forces’ command and control structures impact their capacity to cope with battlefield uncertainty and perform effectively in combat. Other projects investigate the way in which internal military political structures and debates condition phenomena like the international diffusion of innovative military doctrines, the performance of coalition forces on the battlefield, and quality of treatment of prisoners of war. He also studies the drivers of soldier desertion and surrender in battle. Grauer’s work on these topics as well as on the impact of various forms of tactical and operational force employment on combat outcomes has been published in Security Studies, World Politics, and elsewhere.

Prior to coming to GSPIA, Professor Grauer earned his A.B. in Political Science (with Honors) from the University of Chicago and his MA and PhD in Political Science from the University of Pennsylvania.
