Daniel O’Keefe is the Owen L. Coon Professor in the Department of Communication Studies. His research focuses on organizing and synthesizing the substantial body of work derived from persuasion studies—the effects of messages on persuasion and the distinctive problems associated with the development of dependable generalizations about persuasive message effects. His work seeks to derive and integrate findings from the large number of extant persuasion effects studies, especially through quantitative methods for research synthesis (meta-analysis).
