Lewis Ayres is an associate professor of historical theology at the Candler School of Theology and in the Graduate Division of Religion at Emory University. The focus of his work is patristics and the development of Trinitarian theology. A graduate of St. Andrew's University, he went on to study at Merton College, Oxford University, and took a D.Phil. in theology at Oxford in 1994. After three years of teaching in the United Kingdom and four years at Trinity College, Dublin, Dr. Ayres joined the faculty of Duke University Divinity School as an assistant professor of theology in 1999. Two years later, he moved to Emory, where he was appointed to his present position in 2004. He has been the St. Francis Xavier Visiting Fellow in Theology at Liverpool Hope University College, University of Liverpool, and a visiting fellow at the Center for Early Christian Studies at Catholic University of America. A member of the editorial boards of the Journal of Early Christian Studies and of Modern Theology, he is the author of some thirty articles in scholarly journals and chapters in volumes of collected works. He serves as co-editor of the Blackwell Publishers series Challenges in Modern Theology. He is also the co-editor of four books, including (with Andrew Louth and Frances Young) The Cambridge History of Early Christian Literature (2004) and (with Vincent Twomey) The Mystery of the Trinity in the Fathers of the Church, which will be published next year by Four Courts Press. Dr. Ayres is the author of Nicaea and its Legacy: An Approach to Fourth Century Trinitarian Theology (Oxford University Press, 2004), which offers a subtle new reading of the common themes among eastern and western Trinitarian theologies in the late fourth and early fifth centuries, including the "Cappadocians" and Augustine. With Michel René Barnes, he is the co-author of The Spirit of His Mouth: Pneumatology from the Bible to Augustine (in press), and he is presently editing a volume entitled The Trinity Reader for Blackwell and writing two other books, Augustine's Trinitarian Theology and Early Christianity: An Introduction, both for Cambridge University Press.
