Thank you for your offer to volunteer as a chair of a poster or platform session at the upcoming SOT Annual Meeting in San Antonio, Texas. This form will collect your contact information as well as your top three poster/platform categories. New this year: ALL DAY POSTER SESSIONS. Poster presenting authors will not be asked to stand by their posters all day; they will be assigned one of four time blocks. Two chairs for each Poster session will be requested: One to interact with the authors during the assigned time block, and the second to monitor boards to ensure all posters in the session are on display during ToxExpo hours.
