My teaching and research interests cover a broad range of fields related to the 19th- to 21st-century social, cultural, and urban history of Central Europe, including the history of the late Habsburg Monarchy; the history of Budapest and other cities of the region; Jewish history; memory studies; gender history; interethnic relations and intercultural transfer; and the history of migration.

In recent years, my main field of research has been modern and contemporary urban history, with a special focus on Budapest and other Central European cities and their architectural, physical, economic as well as social transformations and urban politics. Besides my recent project in Hamburg, which concentrated on public history in urban contexts, I am currently working on a co-authored, new history of Budapest, placing the city in broader, regional as well as European frameworks. Within that book project, I am covering the period between 1950 and 2010. I have recently published a monograph on the social and cultural history of the “Old Jewish Quarter” of Budapest (so far in Hungarian).  I am the author and editor of numerous other books, including a critical edition of a Holocaust diary and a monograph titled The Social History of Fine Arts in Hungary, 1867-1918. My most recent, co-edited volume is titled Cities and Economy in Europe: Markets and Trade on the Margins from the Middle Ages to the Present (Abingdon and New York, Routledge, 2024).
