Alan moved to Birmingham from the United States in 2014 to research scribal habits in Greek New Testament manuscripts with Professor David Parker. He focussed particularly on Abschriften, manuscripts for which the exemplar known by the scribe has been identified among surviving witnesses. These include two manuscripts copied from Codex Claromontanus (GA 06), a bilingual Greek-Latin copy of the Pauline Epistles, as well as "parent" and "child" manuscripts of the Gospels (one of which was identified in the doctoral dissertation of ITSEE fellow Dr Bruce Morrill). Alan also analysed the copying practice in Papyrus 127, a recently-published manuscript of the Acts of the Apostles which differs from the previously-known recensions in a number of places. Among a number of important conclusions in his thesis, Alan demonstrated that copyists endeavoured to reproduce their exemplar with fidelity: he did not encounter any alterations which were introduced in the text for doctrinal reasons.
