His primary research and teaching interests focus on media and cultural studies of modern Korea, critical theory, popular culture in East Asia, film studies, critical musicology, intellectual history of wartime Japan and postwar Korea, Korean contemporary art, and post/colonial historiography. He is currently revising his book manuscript, Embedded Voices in Between Empires: The Cultural Formation of Korean Popular Music in Modern Times, which explores the historical trajectory of colonial mentalities and the genealogy of cultural modernities and Americanization in South Korea by recontextualizing popular music as a narrative of collective memories and mass trauma.
