The author of eleven books and many articles, her research interests focus on how biblical interpretation bears on the life of faith communities and their response to urgent public issues, particularly the ecological crisis and interfaith relations. Scripture, Culture, and Agriculture: An Agrarian Reading of the Bible (Cambridge University Press, 2009), integrates biblical studies with a critique of industrial agriculture and food production. Biblical Prophecy: Perspectives for Christian Theology, Discipleship and Ministry (Westminster John Knox, 2014), explores the prophetic role and word across both Testaments of the Christian Bible. Her most recent books are Preaching the Luminous Word (Eerdmans, 2016), a collection of her sermons and essays, and Opening Israel’s Scriptures (Oxford, 2019), a comprehensive theological reading of the Hebrew Bible/Old Testament.

A lay Episcopalian, she has long been active as a theological consultant within the Anglican Communion. Her current work explores the arts as modes of scriptural interpretation.
