The 3MT® is a professional and engaging international competition. It challenges PhD students to present their research in language appropriate to an intelligent but nonspecialist audience in the space of three minutes. The competition is based on the premise that the capacity to present a clear, concise and engaging description of their research is an essential skill that all graduate researchers should develop. It also brings our graduate research community together in a spirited and researchfocused activity, inspiring them to share their findings with the wider community.
