Yuhosua "Josh" Ryoo, Assistant Professor

School of Journalism and Advertising

Dr. Yuhosua (Joshua) Ryoo's research interests are at the intersection of digital advertising, medial psychology, and prosocial behavior. Specifically, his research focuses on individual, social, and situational factors of digital and social media and examines how these factors influence people's prosocial decision-making and behavior. In addition to various types of prosocial behavior, such as ethical consumption, environmental sustainability, donation, and corporate social responsibility, the roles of new media (e.g., Youtube) and technology (e.g., AI) are therefore in the scope of his research interests.

Prior to joining the SIU, he taught undergraduate students at The University of Texas at Austin as an assistant instructor. He also served in the Republic of Korea Army as an information and education officer (1st lieutenant), where he was in charge of education, public relations, and advertising.
