She received her doctorate in systematic theology from Marquette University. Wood teaches courses on ecclesiology, Henri de Lubac, the nouvelle théologie, ecumenism, and sacramental theology, as well as more general courses in systematic theology. Her research interests have focused on the theology of ordained ministry, the ecclesial dimension of sacramental theology, the thought of Henri de Lubac, and ecumenical theology. Very active in ecumenical work, she serves on the U.S. Lutheran–Roman Catholic dialogue (1994–present), the North American Roman Catholic-Orthodox Theological Consultation (2005–present), the conversation between the Roman Catholic Church and the Baptist World Alliance (2006–10), and the International Lutheran-Catholic Dialogue (2008–present).

She is an associate editor of Pro Ecclesia and serves on the editorial advisory board of the journal Ecclesiology. Most of her writing explores the connections between ecclesiology and sacramental theology. In addition to numerous articles, she has published Spiritual Exegesis and the Church in the Theology of Henri de Lubac, Sacramental Orders, which has also been translated into Spanish, and One Baptism: Ecumenical Dimensions of the Doctrine of Baptism. She is the editor of Ordering the Baptismal Priesthood and coeditor, with Alberto Garcia, of Critical Issues in Ecclesiology: Essays in Honor of Carl E. Braaten.
