Alexandra's postgraduate study began at St Mark’s National Theological Centre analysing the relationship between the Epistle of Jude and the book of Enoch. She carried out her doctoral work at Macquarie University on the harsh rhetoric of Jude’s epistle in relationship with Jewish woe oracles and Greco-Roman invective. This research led to the publication of her monograph with T&T Clark and subsequent articles on harsh rhetoric in both Jude’s epistle and the gospel of John, published through New Testament Studies, Novum Testamentum, and the Journal of Greco-Roman Christianity and Judaism. Since taking up a position at United Theological College she has begun work on Luke’s gospel looking at the significance of female characters such as Mary, the mother of Jesus.
