My work focuses on art and culture of the 19^th and 20^th centuries, especially on the history and theories of exhibition and museum displays, the role of institutions in the representation of national identity, the cultural transfer between countries, and the work of Adolph Menzel, Max Liebermann, and Max Beckmann, including issues of exile and emigration.
