I am an historical and systematic theologian specialising in two main areas of research: the Eastern Patristic tradition of theology, its philosophical background, and its development up to John of Damascus; and modern theology from the Reformation to the present, with special interests related to nineteenth-century German theology. My published contributions to scholarship include two main works that correspond to these areas of research—Human Nature in Gregory of Nyssa (Brill, 1999; paperback 2014) and Theology as Science in Nineteenth-Century Germany (Oxford University Press, 2013)—along with many articles and edited books.
Uniting this historical research on patristic and modern thought are broader interests in theological anthropology, ecclesiology, and the relation of theological to philosophical developments. These interests emerge not only in previous writings but especially in two current research projects: one traces the emergence of a Christian philosophy in doctrinal debates following the Council of Chalcedon; the other is a systematic-theological reflection on the significance of individuality for the Christian faith.
I have supervised a wide range of graduate research projects on patristic and modern theology and welcome inquiries from students who are interested in undertaking research in these areas.
