Welcome to the ACG 2023 ePoster Hall

ACG is excited to be able to host over 4,200 accepted scientific poster abstracts via an online site this year. All attendees of ACG 2023 can browse the virtual ePoster Hall to view high-quality digital versions of the print posters, many of which include audio recordings by the presenters. The ePoster Hall site will remain open after conclusion of the ACG 2023 meeting. (NOTE: the ePoster Wall Gallery of digital posters opens Sunday, October 22 at 12:00 pm PT / 3:00 pm ET.)

Using the ePoster Hall

  • SEARCH - Use the Search bar in the upper right corner or use the menu at the left to search by title, author, category, etc. Clicking on a title or author name will open a new page where you can click the ePoster image to view it, and if the author has recorded audio, it will play automatically.
  • VIEW - Click the ePoster Wall Gallery to view all of the digital ePosters. Zoom in on details (or pinch in/out with a touch screen device), and use the Search bar to search by author name, affiliation, poster title, and keywords.
  • CONTACT AUTHOR - To send a question or comment directly to an author, click a poster title to view the poster, then click the author’s name to open a new window and use the blue Email button in the lower right to contact them. Authors without a button did not provide an email address.

ACG Awards and Special Recognition

Award recipients are identified by blue ribbon badges. Winners of named and category awards, as well as recipients of Presidential Poster Awards, are chosen by the ACG Abstract Selection Committee based on scores and merit of qualifying abstracts submitted, and the criteria for each award. Each year approximately 5-7% of accepted abstracts receive Presidential Poster Award distinction for high quality, novel, unique and interesting research.
