Joe Walther

CRML Affiliated Faculty

Distinguished Professor, Communication



Dr. Walther's research focuses on mediated interactive communication, and the impact of interpersonal and social forces in the attitudes, behaviors, and relationships people develop via mediated interaction, in groups, educational settings, and inter-ethnic conflict. He developed the social information processing theory of mediated communication, the hyperpersonal model of online communication (by which people experience exceptionally intense emotions and connections), and warranting theory, accompanied by numerous behavioral studies. He is currently extending his work into new explanations for online hate.
