At one time a scientific-medical editor and writer in the US and Hong Kong, I have taught writing, communication, and rhetoric at American universities for over a decade. My research and teaching interests are rooted in questions about how and why people believe the things that they do, and how language and interactional practices generate, shape, and influence those beliefs and the values they are based on—which, in turn, shape and influence ideas of ourselves and our identities in relation to others. In addressing such questions, my scholarship has drawn from a range of disciplinary perspectives (in the humanities, social sciences, and cognitive sciences) to inform theories of rhetoric and communication, with a particular emphasis on digital media and political communication. A recent example is a chapter in the Routledge Handbook of Digital Writing and Rhetoric on the social media and rhetorical practices of the 2016 Standing Rock protests. In my classes, we tend to pay special attention to how forms of communication and interaction make possible or constrain different ways of thinking by shaping our assumptions and expectations.
