Abstract
As technical and professional communication (TPC) has broadened its scope to encompass various contexts, scholars have increasingly incorporated queer epistemologies to deepen our understanding of these areas. This chapter traces the evolution of queer theory from identity-based research to a more comprehensive epistemology and methodology, emphasizing its significance beyond LGBTQIA+ identities and presents a case study demonstrating how queer epistemology can be applied in TPC courses to highlight the rhetorical complexities often overlooked in conventional approaches. By challenging normative practices and embracing polyvocality, affect, and disruption, queer theory offers valuable insights for TPC scholars and educators, enriching both research and pedagogy in the field.
