Virtanen has focused on the spread of American culture and the cultural exchange between the European and American cultures, which has resulted in a doctoral dissertation ''Settlement or return'' (1979), where the return of Finnish emigrants from America is studied. He has published widely on migration history and ethnicity, U.S. and Canadian history and society, European integration processes, methodology of history, and university and science policies.
