In 2002 I finished a PhD in Communication and Rhetoric from the Department of Language, Literature, and Communication at Rensselaer Polytechnic Institute (RPI) in Troy, NY. I arrived at RPI with an interest in Rhetoric and Composition and technology. When I left RPI I had combined those interests with a study of human computer interaction, technological mediation, and new media development. I now do research that explores the mediating effects of technology on information-rich, cooperative work practices. My current work is on mobile information technology and the way that it is used to coordinate improvisational and cooperative uses of information. This current branch of my research is leading me to question the stability of categories such as "writers" and "readers." I am investigating the ways that these categories are starting to collapse into one another. Readers in information-saturated work places interact with the complex streams of multimodal information around them. They write their own texts by selecting and arranging the information that is pertinent to their needs and interests.
