Hello. I'm an Associate Professor of Rhetoric and Communication in the Department of English Language & Literature, and author of the NCTE award-winning book, Instruction and Technology: Designs for Everyday Learning (The MIT Press, 2010).

Previously, I was an Associate Professor of Distance Learning in the College of Education at North Carolina State University and, before that, an Associate Professor of Rhetoric and Technical Communication in the Department of English, also at North Carolina State University. Much of my research has focused on human-computer interaction, beginning with my co-authored book, Online Help: Design and Evaluation (Ablex, 1993). I have published numerous articles, including in Technical Communication, Human-Computer Interaction, Journal of Technical Writing and Communication, and IEEE Transactions on Professional Communication as well as proceeding papers, including with the ACM SIGDOC. Additionally, I have published chapters in the award-winning Solving Problems in Technical Communication (U of Chicago P), The Human-Computer Interaction Handbook (Lawrence Erlbaum), Innovative Approaches to Teaching Technical Writing (Utah State UP), Digital Rhetoric and Global Literacies (IGI Global), The Society of Text (The MIT Press), The Computer Science and Engineering Handbook (CRC Press), and the award-winning Computers and Technical Communication (Ablex).

My current project is a book-length manuscript, entitled “Learner,” an exploration of the rhetoricity of learning across the life span.

I live in the Waterloo Region, Ontario, Canada, with Dr. Ashley Rose Mehlenbacher, my wife and collaborator. For 27 years, I lived and worked near Research Triangle Park (RTP) in Raleigh, North Carolina, USA, and before then lived in Pittsburgh, Pennsylvania, for four years.
