Dr. Ioana Oltean specialises in the archaeology of the Roman Empire, particularly in its European provinces, and in aerial archaeology. She is interested in the reconstruction of ancient landscapes, the analysis of settlement pattern evolution and in social changes from the Late Iron Age to the Roman period in the Lower Danube area and in Britain, in order to quantify the nature and extent of their change through Roman imperialist expansion. She has been involved since 1998 in establishing aerial reconnaissance as a standard method of archaeological prospection in Romania.
