I specialize in the global dimensions of twentieth century American religion and am broadly interested in the intersection of American Christianity and the emerging field of the US in the World.

I have also researched and written on transatlantic religious networks and the history of German Protestantism.

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.
