Jennifer Trimble works on the visual and material culture of the Roman Empire, with particular interests in portraits and replication, urbanism and the city of Rome, and ancient mapping.  Her monograph Replicating Women in the Roman Empire is in press with Cambridge University Press (2011); it investigates the role of visual replication and sameness in constructing public identity and in articulating cultural tensions between empire and place.  Trimble is also co-director of the IRC-Oxford-Stanford excavations in the Roman Forum (now being prepared for publication), focused on the interactions of commercial, religious and monumental space.  She co-directed Stanford's Digital Forma Urbis Romae Project, a collaboration between computer scientists and archaeologists to help reassemble a fragmentary ancient map of the city of Rome.  Her current book project, Mapping Rome: Representation and the City on the Severan Marble Plan, explores social and spatial relations in the city of Rome.
