Professor Sieg joined the Center in the fall of 2002 as Associate Professor of German. Prior to her appointment at Georgetown, Professor Sieg was a faculty member of the Department of Germanic Studies at Indiana University. She holds a Ph.D. in Drama from the University of Washington, Seattle. She has received several awards and grants, among them a Humboldt Fellowship, which she used to pursue research in Berlin during the 2001-2002 academic year, and a Senior Faculty Research Award (Fall 2008), which allowed her to complete her most recent book.

Professor Sieg is the author of three books on twentieth-century German theater and performance, which focus on the politics of nationality, race/ethnicity, and gender/sexuality. She is part of a research group examining the Eurovision Song Contest as an example of transnational popular culture. In addition, her current research looks at the documentary work performed at an immigrant theater in Berlin.

She has organized a number of symposia, film series, and conferences on topics relating to contemporary German and European culture, including "Queer European Cinema"; "Shadows and Sojourners: Images of Jews and Antifascism in East German Cinema," and "European Cosmopolitanism?"

As a member of the core faculty Professor Sieg teaches the MAGES core course on Theorizing Culture. Since 2005, she has also served as Field Chair of the Culture and Politics program.
