Joshua Gunn Dr. Joshua Gresham Gunn (Ph.D., University of Minnesota, 2002) teaches and researches at the University of Texas at Austin, where he is an Associate Professor of Communication Studies and a Faculty Affiliate in the Department of Rhetoric and Writing. He also teaches public speaking as an adjunct professor at Southwestern University, in Georgetown, Texas. Josh's research tends to focus on how people use and abuse signs and symbols. In this context, his attention to music, religion, and human affective experiences (e.g., love) are part of a deeper interest in the limits of human representation, self-understanding, and self-fashioning. As a teacher and student of popular culture, Josh is currently completing an academic book on ghosts and their haunting speech in U.S. culture.
