She specializes in work on (mainly queer) sexuality and its intersections with gender, race, indigeneity and class. She explores these issues in three sets of texts --- science fiction and speculative fiction, Canadian literature and film, and worldwide Indigenous film cultures ---and is particularly interested in the intersections between these areas. She is the co-editor with Veronica Hollinger and Joan Gordon of Queer Universes: Sexualities in Science Fiction and has published widely on queer perspectives on science fiction as well as on contemporary queer cultures in Canada. She is also the co-author, with Susan Knabe, of Zero Patience, part of the Arsenal Pulp Press Queer Film Classics series.
