Devin Manzullo-Thomas is assistant professor of American religious history, director of the E. Morris and Leone Sider Institute for Anabaptist, Pietist and Wesleyan Studies, and director of archives at Messiah University.

Devin regularly teaches courses in the history of Christianity. In addition, he teaches in the university's Peace and Conflict Studies program, its Honors Program, and its Interdisciplinary Studies program.

In his scholarship, Devin pursues two distinct research agendas. As a denominational historian of the Brethren in Christ Church, he draws on his training in cultural and religious history to understand how this small religious community has changed over time. As a public historian of American religion, he studies the ways in which religious communities—especially Christian communities—construct, commemorate, and contest the past in public through historical societies, heritage sites, museums, monuments, archives, and other institutions of public memory.

Devin is the author of Exhibiting Evangelicalism: Commemoration and Religion's Presence of the Past, published in 2022 by the University of Massachusetts Press in their "Public History in Historical Perspective" series. The book is the first history of museums and historic sites operated by evangelical Christians in the United States. In addition, Devin's articles and reviews have appeared in Church History, The Christian Century, Fides et Historia, Brethren in Christ History and LifeMennonite Quarterly Review, The Wesleyan Theological Journal, Anabaptist Witness, The Conrad Grebel Review, and other scholarly and popular publications.
