Most of my research focuses on the conflicts that arise between First Amendment values and other important constitutional principles such as intellectual property rights and the Sixth Amendment rights of criminal defendants. I am the co-author of Mass Communication Law in Pennsylvania (New Forums Press, 2003) and of the RTNDA project "Hidden Cameras, Hidden Microphones: At the Crossroads of Journalism, Ethics and the Law" (1998).
