Professor Wolff works on the history of Eastern Europe, the Habsburg Monarchy, the Enlightenment, and on the history of childhood. He tends to work as an intellectual and cultural historian. He has been most interested in problems concerning East and West within Europe: whether concerning the Vatican and Poland, Venice and the Slavs, or Vienna and Galicia. He developed the argument that Eastern Europe was "invented" in the eighteenth century, by the philosophes and travelers of the Enlightenment, who attributed meaning to a supposed division of Europe into complementary regions, Western Europe and Eastern Europe. He has analyzed Western perspectives on Eastern Europe as a sort of "demi-Orientalism," negotiating a balance between attributed difference and acknowledged resemblance. Considering Venetian perspectives on Dalmatia and Habsburg perspectives on Galicia, he has attempted to explore the meaning of "Eastern Europe" within imperial frameworks and the ideology of empire. His research on the history of childhood has included projects on child abuse in Freud's Vienna and child abuse in Casanova's Venice. His current research concerns Turkish subjects on the European operatic stage during the long eighteenth century, and analyzes musical and dramatic representations in the context of European-Ottoman relations. His new book will be published in 2016: The Singing Turk: Ottoman Power and Operatic Emotions on the European Stage from the Siege of Vienna to the Age of Napoleon.
