Philip Deloria is a professor of history at Harvard University. His research and teaching focus on the cultural and ideological intersections of Indian and non-Indian worlds. His first book, Playing Indian (1998), traces the tradition of white "Indian play" from the Boston Tea Party to the New Age movement, while his Indians in Unexpected Places (2004) examines the ideologies surrounding Indian people in the early twentieth century and the ways Native Americans challenged them through sports, travel, automobility, and film and musical performance. He co-authored with Alexander Olson American Studies: A User's Guide (2017), which offers a comprehensive treatment of the historiography and methodology of the field of American Studies. He is a coeditor, with Neal Salisbury, of The Blackwell Companion to American Indian History (2001) and, with Jerome Bernstein, of C.G. Jung and the Sioux Traditions (2009) by Vine Deloria Jr. His most recent book is Becoming Mary Sully: Toward an American Indian Abstract (2019). Prior to joining the faculty at Harvard, Deloria taught at the University of Colorado and at the University of Michigan where he also served as the associate dean for undergraduate education and directed the American culture and Native American studies programs. He is a trustee of the Smithsonian Institution's National Museum of the American Indian, where he chairs the Repatriation Committee; a former president of the American Studies Association; and an elected member of the American Academy of Arts and Sciences. He is currently completing a project on American Indian visual arts of the mid-twentieth century and coediting, with Beth Piatote, "I Heart Nixon: Essays on the Indigenous Everyday."
