Research Tudorie's research intersects theology and history, focusing on Byzantine imperial ideology, relations between spiritual and political authorities in Byzantium, contemporary Byzantine historiography, accounts of Western travelers to Constantinople in the late 16th century and relations between the Greek Orthodox community and Ottoman rulers (15th–17th centuries), with emphasis on Patriarch Dositheos II of Jerusalem (1669–1707).
