I specialize in the global dimensions of twentieth century American religion and am broadly interested in the global scope and engagement of American Christianity. I have also researched and written on transatlantic religious networks and the history of German Protestantism

My first book, God’s Marshall Plan, explores how American Protestants exported their domestic culture wars to Germany in the aftermath of two world wars. Yet in seeking to remake Germany in their own image, they instead found themselves remade. In particular, this book shows how the American struggle for Europe’s soul fostered more tolerant theologies of global and civic engagement that transformed transatlantic religion, politics, and diplomacy.

Along with my academic publications, I enjoy writing for a general public audience and have published short pieces with The New York Times, The Washington Post, and Christianity Today.
