My teaching involves the history of religions in Greek and Roman antiquity,
with a special interest in early Christianity. Most of my published
work is on the Gospels: Mark, Luke, the Q source, and the Coptic
Gospel of Thomas.
A second area of research is Coptic: the language and literature
of Egyptian Christianity (and Gnosticism too) in Late Antiquity and
the early Middle Ages. My own writing projects these days center on
Luke, Thomas, and various Coptic liturgical and hagiographical texts.
