I earned a MCS (Master of Christian Studies) and a ThM from Regent College in Vancouver, Canada, and a PhD in (religious) history from the University of Stirling in Scotland. In 2012, I was elected a Fellow of the Royal Historical Society (FRHistS). After graduating from Taylor University in 1998 with a BA in business administration, I worked as a financial consultant with two brokerage firms in Florida before resigning in 2004 in order to pursue graduate studies. My research interest is in eighteenth-century British and American religious history and thought, the history of evangelicalism, and the history of the book. My first book, Enlightened Evangelicalism: The Life and Thought of John Erskine (Oxford University Press, 2011), was a finalist for the Scottish History Book of the Year.  My second book, an edited anthology entitled, Early Evangelicalism: A Reader, was published by Oxford University Press in August, 2013. My third book with Oxford University Press came out in 2016 and is entitled, Jonathan Edwards and Transatlantic Print Culture. In it I analyzed how Edwards's works were published in the eighteenth-century transatlantic world. I also have two forthcoming edited volumes. The first is The Oxford Handbook of Early Evangelicalism (Oxford University Press), which will include more than thirty articles by the world’s leading scholars on the subject of evangelicalism in the long 18th century. The second book is entitled Understanding and Teaching Religion in US History. Coedited with Karen Johnson of Wheaton College, this University of Wisconsin Press book will include essays by several scholars on the importance of including religion in American History, and will be used as a resource for high school and college history teachers. In addition to my books, I have published articles and essays on religious history and thought in Books & Culture, Evangelical Quarterly, the Journal of Religious History, Printing History, Records of the Scottish History Society, the Scottish Journal of Theology, and Jonathan Edwards Studies.
