Abstract
Last semester I gave a talk to a small group of graduate students and faculty in the Department of Animal and Food Sciences in the College of Agriculture on my campus. As one of several invited speakers for the department's graduate seminar series, the purpose, I was told, was straightforward: model an effective presentation for the students. I teach courses in technical and professional communication so I imagined it might also be useful to discuss presentation strategies. I concluded by giving an overview of my own research interests---broadly, visual communication---and briefly described a project I am working on related to scientific graphics and historic public health maps.
