* An ELEVATOR SPEECH is a short summary used to quickly and simply define your research and its significance. Researchers are asked to summarize their poster by speaking for up to 2 minutes and showing 2 slides (maximum, no animations allowed). This short speech should attract participants to visit your poster during the poster session. IMPORTANT: Please send us your 2 slides (PowerPoint) by email (christine.barnard@cen.ulaval.ca) before March 11, 17h00.
