The Three-Minute Thesis (3MT) presentation has appeared as a new genre to meet the changing needs of graduate students in the academic world. Although some research is available on the generic structure and strategies characteristic of this genre, a comprehensive and in-depth account of this genre is lacking. Therefore, the objective of this study is to provide a holistic analysis of the rhetorical structure and linguistic features of this genre using 25 recordings of 3MT presentations. The focus is on simplification and engagement strategies used by PhD students to target a nonspecialist audience and engage them to build rapport with them. The findings indicate that simplification is achieved by omitting conceptually complex moves, conflating moves for brevity and simplicity, and defining scientific terms and concepts. In addition, engagement strategies such as attention-getting, explanatory, interactive and personalised strategies are used to capture and maintain the attention of the audience. The findings show that 3MT presentations have evolved into a unique genre with distinct features through recontextualisation which involves both simplification and engagement, enabling PhD students to share and promote their own research simultaneously, with a non-specialist and disciplinarily heterogeneous audience.
