In this episode, host Danielle Deveau interviews Devon Moriarty, a rhetorician completing her PhD at the University of Waterloo. They discuss the politics of science and how rhetorical moves can sometimes shut down scientific debate and learning. We also dig into the archives and re-broadcast an interview by Dr. Heather Love (Assistant Professor, Dept. of English Language and Literature, University of Waterloo) featuring Dr. Ashley Mehlenbacher (Associate Professor, Department of English Language and Literature, University of Waterloo), currently a Canada Research Chair in Science, Health, and Technology Communication. They discuss Dr. Mehlenbacher's book Science Communication Online: Engaging Experts and Publics on the Internet.
