Paul MongeauPaul Mongeau, who earned his Ph.D. at Michigan State University, is a professor in the Hugh Downs School of Human Communication. He is interested in communication in relationships and the processes of persuasion and social influence. Both of these topics are relevant to the Health Communication Initiative.
