Recent research has illuminated some of the ways in which multilingual writers project multiple identities in their writing, conveying disciplinary allegiances as well as more personal expressions of individuality. Such work has focused on writers' uses of various verbal expressions, but has to this point overlooked the ways in which writers manipulate the visual mode as a means for identity expression. The present study examines expressions of identity in a corpus of multimodal texts written by four multilingual graduate student writers. I consider how the writers' uses of various verbal and visual expressions in their PowerPoint presentation slides project both disciplinarity and individuality, and how each individual's habitus has been influenced by both the discourses they have encountered and their personal reactions towards those discourses.
