A poster session is an alternative way to provide information. Instead of using a series of slides in an oral presentation, selected presenters can display a board in Boylston Hallway. Their boards will be placed in a highly visible area at the entrance, where conference attendees can easily view them. No concurrent activities are scheduled at this time—it is reserved exclusively for the poster presentations. Posters will be left on display until Wednesday, February 27, 3:00 p.m., for participants to view between other sessions.
