Aaron O’Connell is Associate Professor in the Department of History at the University of Texas at Austin. His scholarly interests span four inter-related fields: 20th century military history, U.S. foreign affairs, cultural history, and American politics. His scholarly publications focus on understanding the effects of U.S. military influence and infrastructure inside and outside the United States. His public history pieces mostly concern how the U.S. military affects contemporary domestic and political culture. He teaches courses in military history, U.S. foreign policy, U.S. military culture, and the U.S.’s role in the world since 1898. Dr. O’Connell is the author of Underdogs: The Making of the Modern Marine Corps, which explores how the Marine Corps rose from relative unpopularity to become the most prestigious armed service in the United States. He is also the editor of Our Latest Longest War: Losing Hearts and Minds in Afghanistan, which is a critical account of U.S. efforts in Afghanistan since 2001.
