Research and Teaching Interests

His interests are diverse but he has focused on reorienting U.S. religious history in terms of the Atlantic World, the Pacific World, and the Western Hemisphere. Recent articles and chapters have considered method and theory in the historical study of religion as well as space and place, migration, and art and architecture. Tweed’s transnational studies have focused on Latinos and Asians, and his work on religious history has highlighted Catholics, Protestants, and Buddhists. His current research projects include a history of religion in America from the pre-colonial period to the present. His teaching reflects those research interests. Tweed teaches courses on religious history and historiography, including an undergraduate survey and graduate seminar on U.S. Religious History.


Tweed’s research, which includes six books and a six-volume series of historical documents, has been supported by several grants and fellowships, including three from the National Endowment for the Humanities. He edited Retelling U.S. Religious History and co-edited Asian Religions in America: A Documentary History, which Choice named an “outstanding academic book.” He also wrote The American Encounter with Buddhism, 1844-1912: Victorian Culture and the Limits of Dissent and Our Lady of the Exile: Diasporic Religion at a Cuban Catholic Shrine in Miami, which won the American Academy of Religion’s award for best historical book. Tweed’s Crossing and Dwelling: A Theory of Religion was published by Harvard University Press in 2006, and his study of the Basilica of the National Shrine of the Immaculate Conception appeared in 2011 as “America’s Church”: The National Shrine and Catholic Presence in the Nation’s Capital, 1917-1997. America’s Church also received the annual book award by the American Academy of Religion. In 2015 Tweed served as the president of the American Academy of Religion.
