I have wide interests in the history of the Latin and Greek languages, ancient sociolinguistics and bilingualism, the languages and epigraphy of the ancient Mediterranean and comparative Indo-European studies. I have particular interests in the historical sociolinguistics of Latin; the other ancient Languages of the Italian peninsula especially Sabellian and Etruscan; and the history of the Armenian language. I am currently Principal Investigator of the AHRC funded project ‘Greek in Italy’. I am editor of the oldest scholarly journal devoted to the general study of language and languages that has an unbroken tradition,Transactions of the Philological Society.
