His research concerns the multilingual literary culture of high medieval Britain, with particular attention to Latin, Anglo-Norman French, Old and Middle English, and Welsh. He is especially interested in discovering networks of textual exchange between Wales and England, and in studying the English-language writing of the long-twelfth century (c.1066-1215). Professor Smith’s research also extends to Welsh-language material in North America. Overall, his research argues for a vision of medieval British literature that is diverse, transnational, and resolutely multilingual. He is currently a Mellon Fellow in Critical Bibliography at the Rare Book School.
