I work on the history of colonial America, the Atlantic World and the United States in the eighteenth and nineteenth centuries, with particular interests in religion, nationalism, race and empire. I did my BA and MPhil at Cambridge, and completed my PhD at Princeton. My first book, Providence and the Invention of the United States (Cambridge), explores the idea of America as a chosen nation from the founding of Virginia to the end of Reconstruction. My second, Bind Us Apart (Basic Books), examines the discomfiting relationship between ideas of racial equality and programmes for racial separation in the early American republic. 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. After nearly twenty years away from Cambridge, it’s very nice indeed to be back.
