I have published on various forms of nineteenth-century display culture, including zoological gardens, ethnographic exhibitions (Völkerschauen), and Wild West shows in Germany. I have also published on the interrelationship of science, technology, and popular culture in specific situations--namely, the vital importance of the phonograph and the archive to the formation of ethnomusicology in Germany, and the cinema’s function as an instrument of cultural power in the writings of Hugo Münsterberg. I am co-editor of Germany’s Colonial Pasts (Nebraska, 2005) and author of Carl Hagenbeck’s Empire of Entertainments (Washington, 2009). I also wrote Ferocious Reality: Documentary According to Werner Herzog, which was published by Minnesota in fall 2012. My edited collection, Werner Herzog: Interviews (University Press of Mississippi), appeared in spring 2014. Currently, I'm writing a little book on Herzog's Aguirre, the Wrath of God.
