Grant Cos

Director for Graduate Programs and Professor
3224 Eastman Hall

Professor Cos teaches a complement of courses that blend empirical, social scientific theory with a humanistic focus. His research interests center on the Aristotelian trilogy of politics, ethics and rhetoric. More specifically, these interests have manifested themselves into the study of mediated speechmaking and political campaigning, "mash-up" online advertisements and politics,  and contemporary instances of dissent during wartime.
