Her primary concentration has been on the application of
archaeology to history of the
longue durée in both the
Italian peninsula and the countries of
North Africa. Her work has focused on social and economic aspects of Roman landscapes of all periods, with special regard to the interaction between Roman and non-Roman peoples at their points of contact in areas such as slave markets, the
limes, urban areas like Cosa in Italy and Meninx, Utica, Sétif and Volubilis in North Africa and an imperial Villa, Villa Magna, in Italy.
