Trimble's field is the art and archaeology of the Roman Empire, with a focus on constructions and receptions of visual culture. She is completing a book for Cambridge University Press entitled Replicating Women: Image, Place and Power in the Roman Empire, which explores tensions between images and social power, individual and collective, and empire and place. In her work on the Severan Marble Plan, an enormous and detailed map of the city of Rome carved in the early 3rd c. CE, she is interested in questions of cartographic representation, viewing and response, and the dynamics of urban space. Jen has excavated in Turkey, Tunisia, Germany and France and has directed magnetometry surveys in Italy. She currently co-directs the IRC-Oxford-Stanford excavations in the Roman Forum Post Aedem Castoris, which examine the economic infrastructure of the Forum and the interactions of commercial and monumental space over time.
