Karen Kilby is Bede Professor of Catholic Theology at the University of Durham, where she is also Director of the Centre for Catholic Studies. She has published widely in systematic theology, including monographs on Karl Rahner and Hans Urs Von Balthasar. A number of her articles—especially on the Trinity, and evil—have already become key points of reference in the theological literature; are included in the recent collection, published by Bloomsbury, God, Evil and the Limits of Theology.
