Antonio’s research program unites an interest in the state/society nexus with a focus on the consequences of globalization on local peoples, now and in the past. He has worked on themes ranging from violence in society, state formation, social memory, the construction of locality, and, more recently, on conceptions of citizenship, belonging, and social exclusion in the twenty first century. A regional specialist in southern Europe and the Mediterranean, his interest in history centres on perceptions of the past and how they inform social action in the present. This latter concern has influenced his research and writing on Sardinia, where he has conducted research since 2002, and yielded a monograph titled Legacies of Violence: History, Society, and the State in Sardinia (University of Toronto Press, 2015). More recently, Antonio has conducted research on Sicily examining the mechanisms by which refugees and migrants are integrated within their host communities. Ongoing research on Lampedusa is allowing him to examine how a tiny island community responds to the arrival of undocumented migrants to its shores, offering insights into the discordant dynamics of hospitality and xenophobia at the local level.
