He has held visiting fellowships in the UK, Europe, North America and Australia, and is a member of the Center of Theological Inquiry in Princeton.

Professor Davidson has taught and supervised extensively in Christian doctrine and in patristic theology and history. He has published widely in patristics, particularly in Latin or Western traditions, including the definitive critical edition of the first 'systematic' treatise on Christian ethics, the De Officiis of Ambrose of Milan (2 vols, Oxford University Press, 2002), and two widely-used volumes on early church history. He is currently completing an historical and theological study of 'Arianism' for Cambridge University Press and editing The Cambridge Handbook of Early Christian Theology. In systematic theology, he has written primarily on Christology, soteriology and the doctrine of God (e.g., God of Salvation: Soteriology in Theological Perspective, ed. with Murray A. Rae, Ashgate, 2011). He has a book on salvation due to appear with Bloomsbury T & T Clark in 2018; his other current projects include the completion of a major 2-volume study on Christology, history and ethics, an edited collection on soteriology, and a book on theological method. He is contracted to produce a volume on eschatology for Zondervan Academic's New Studies in Dogmatics (2019). He is a founding series editor of Bloomsbury T & T Clark's Studies in Systematic Theology monographs series.

He has published in, e.g, Journal of Theological Studies, International Journal of Systematic Theology, Journal of Early Christian Studies, Scottish Journal of Theology, Vigiliae Christianae, Recherches de Theologie Ancienne et Medievale, Studia Patristica, Irish Theological Quarterly, Journal of Reformed Theology, Theology, Catholic Historical Review, Ars Disputandi, Classical Review.
