Bede Professor of Catholic Theology at Durham University, Karen Kilby became the second occupant of the first endowed chair of Catholic theology at a university in the United Kingdom when she was appointed in 2014. Her research and writing has engaged closely with the work of two major twentieth-century theologians, Karl Rahner and Hans Urs von Balthasar. She also has written about the doctrine of the Trinity and the place of mystery in Christian thought. A new focus is the place of suffering in Christian thought. A summa cum laude graduate of Yale University, Dr. Kilby studied mathematics and theology at Cambridge University, and earned a Ph.D. in religious studies at Yale in 1994. She did postgraduate work at the University of St. Andrews as a Gifford Research Fellow, and in 1997 served as a special lecturer in theology at the University of Nottingham. The next year she moved on to the University of Birmingham as a lecturer in theology, returning to Nottingham as an associate professor of theology and religious studies in 2006 and subsequently serving for three years as head of the Department of Theology and Religious Studies. She was named a full professor in 2013, a position she held until she accepted appointment as a professor of theology at Durham later that year. Dr. Kilby has held an Arts and Humanities Research Board grant and an Arts and Humanities Research Council fellowship. A former president of the Catholic Theological Association of Great Britain and the incoming president of the Society for the Study of Theology, she is a member of the editorial board of the Fortress Press book series, Shapers of Modern Theology. In addition to papers published in academic journals, she is an editor (with Ian McFarland, David Fergusson, and Iain Torrance) of the Cambridge Dictionary of Christian Thought and (with Simon Oliver and Tom O’Loughlin) of Faithful Reading: New Essays in Theology in Honor of Fergus Kerr (2012) and of three other books: Karl Rahner: Theology and Philosophy (2004), The SPCK Introduction to Karl Rahner (2007), and, most recently, Balthasar: A (Very) Critical Introduction, a deft study of the recurrent patterns in Balthasar’s thinking and the influence of his life experience on them, which was published by Wm. B. Eerdmans in 2012.
