I did my BA and M.Phil. at Cambridge, and completed my Ph.D. at Princeton under the supervision of Daniel T. Rodgers. Having taught at Princeton, Simon Fraser University in Vancouver, and the University of York, I joined the History Faculty at Cambridge in 2014. I have been a faculty fellow at the Stanford Humanities Center (2009-10), a British Academy Mid-Career Fellow (2013-14), and the Senior Visiting Research Fellow at the Rothermere American Institute in the University of Oxford (2013-14). I've written about American history for the Nation magazine, the Times Literary Supplement, the Guardian, and the London Review of Books.
I work on the history of colonial America, the Atlantic World and the United States in the eighteenth and nineteenth centuries.
My first book examined the emergence of American religious nationalism from the founding of Virginia to the collapse of Reconstruction. I'm currently finishing a book on the unsettling relationship between ideas of racial equality and programmes for racial separation in the early American republic. I've published a number of articles on racial removal projects from the American Revolution to the Civil War. My next project is a history of American ideas about imperialism from the mid-eighteenth century through the early twentieth, with a focus on how Americans viewed other people's empires.
I have side interests in the history of contemporary American evangelicalism, and especially in the increasingly popular view among evangelicals that the End Times are fast approaching; and in the history of contemporary international relations.
