O’Sullivan’s scholarship focuses on the social aspects of mediated communication—or communication in any form of interaction that is not face-to-face, including older as well as newer communication technologies. He is interested in developing theories of communication that transcend specific media channels and level of analysis. His work bridging the fields has been published in such places as the Journal of Language and Social Psychology and the Journal of Applied Communication Research and has been delivered the International Conference on Language and Social Psychology and the International and National Communication Associations.
In addition to his research, O’Sullivan teaches many courses examining the intersections between technology and communication. His Communication Technology and Impacts (COM 218) course introduces students to historical and conceptual approaches to understanding communication technologies. Social Dynamics of Communication Technologies (COM 318) provides students with a foundation in communication technology studies. In New Technology Law and Policy (COM 363), students investigate socio-political issues involving technology and communication, such as privacy, copyright, cybercrime, and hate speech. O’Sullivan’s graduate students address the role of channel (medium) in the communication process in Foundations of Mediated Communication (COM 418) and examine the influence of technology in bridging research and pedagogical gaps within the discipline of Communication in New Technologies at the Intersection of Mass and Interpersonal Communication (COM 492).
O’Sullivan has served the University and his field in relation to technology. At ISU, he currently serves on the College Curriculum Committee, the LILT Advisory Committee, and the Executive Committee for Academic Technology.
