He specializes in the religious history of early modern America and Britain, with a focus on the methods of cultural and intellectual history. His research interests center on early modern mysticism, Christian primitivism, secularization and modern spirituality, and religion and nature. He is currently revising a manuscript entitled Evangelical Enchantment: Everyday Religion in Antebellum America (contracted with Harvard University Press), which traces the ways in which early American evangelicals engaged the spiritual potential of the natural world in daily life. His new project attempts to chart a cultural history of blood in early modern Christian devotional life.
