As we draw on our experiences with 3MT®, including aspects of organizing, mentoring and competing, our webinar addresses important topics in the art of effective live communication of complex technical material in language suited to a non-specialist audience. Much of what we discuss, however, is also applicable to specialist presentations designed for specialist audiences; for example: story-telling, trust, first impressions, citation, subtext, authenticity, articulation, etiquette, slide composition, respecting your audience, admitting setbacks, and more. As examples, we analyze and discuss 3MT® case studies from several disciplines and suggest tools and strategies to for you to deliver your most engaging talk ever!
