Research Interests and Questions

My primary interest lies in understanding the remnants of the Cold War and communist periods in Eastern and Southeastern Europe. For Western Europe, I am particularly drawn to colonial histories and Napoleonic landmarks, while in the former Eastern Bloc nations, I want to uncover sites associated with communist regimes.

In countries such as the Czech Republic, Hungary, Slovakia, and Croatia, I am especially curious about whether visitor-accessible sites or museums highlight the communist era. For Croatia, I am interested in Tito’s Yugoslavia, given its non-alignment with the Soviet Union and unique Yugoslav identity.

Additionally, I am considering visiting the Sudetenland to see WWII fortifications, although I have some concerns about their similarity to structures in Alsace. I am also curious whether there are any remaining traces
