Czaplicka has taught in Hamburg, Germany, at Harvard, and Humboldt University in Berlin. His publications have dealt with the pictorial imagery of Berlin, Americanism in Germany, Austrian exile artists, and commemorative practices and urban history in East-Central Europe. Recently he edited a collection on rewriting urban history and European immigration. Together with Felix Lutz, he is engaged in a study of German-American cultural-political relations that concentrates on the period 1900–1933.
