Talk Length

You are allowed 20 minutes (total) for you oral presentation. We suggest limiting you talk to 17 minutes to allow 3 min for questions and interaction with the audience.

The session chair will keep everyone on schedule and signal you when you have 3 minutes and 1 minute left. Many people also use a timer or clock app on their cell phone to keep track of time themselves. Be sure to silence your phone before entering the session.

Make sure you visit the session room at least 20 minutes before the start of the session, to load your PowerPoint file, get a feel for the podium and clicker, and the screen projection.
Content: Your presentation should provide an overview of your project(s) and be relevant to your abstract.


Presentation should be in a format compatible with Windows PC software. (PowerPoint.) Using the “insert” menu option in PowerPoint, you can embed audio and video files into your presentation, but doing so will increase the file size, especially if it is a long segment. We recommend doing so sparingly. If you are unfamiliar with using PowerPoint, a number of tips and tricks are provided on pages 4-8 of this document.

Oral Sessions

Oral presentations have been organized by topic into 1-hour long sessions that consist of three 20-minute talks. As you prepare your presentation, please remember that all presentations must be uploaded to the computer in the session room 20 minutes before your session begins. An technician or the session chair will be there to help you upload your presentation file(s) and show you the podium, screen, and clicker. Uploading your files early ensures a smooth transition between presentations and avoids confusion.
