Raja’s research focusses on classical art and archaeology in its broadest sense with particular expertise in the visual cultures of the ancient Mediterranean and its bordering regions, including iconography and portrait representations in the Hellenistic and Roman worlds (primarily the Eastern Mediterranean), urban and landscape archaeology, sites and their societies’ multiple networks from the Hellenistic to the medieval periods. While being a classical archaeologist, she also works in fields intersecting traditional archaeology and natural sciences, bringing high-definition studies of the past to the forefront – an approach, which has most prominently been pioneered through the work done within the framework of UrbNet, since 2015.
