Temporary posters are denoted as “Only viewable on Nov. 20” and will have recording thumbnails available only on Nov. 20.
  5. Live Parallel Sessions have LIMITED seating! In the spirit of creating as much of an in-person experience as possible, we have limited the maximum number of attendees in the live parallel sessions to 200 to allow everyone to turn on their videos and engage in the live Q&A with the presenters (last 15 minutes of each session). All Zoom sessions will open 15 minutes prior to their official start. Get there early to grab a spot! Please note there is no limitation to the number of attendees at our opening event, plenary session, and closing session.
  6. Get Help! Technical support is available for Zoom - just email shamstra[at] or dkulik[at] For all other questions please email [email protected]

How to engage with presenters and other BigSurv20 attendees?

  1. All sessions!We created slack channels for each session to engage with presenters and attendees alike. Simply join the slack channel of the session you are interested in and have fun! And don't forget to explore the other slack channels around the conference.
  2. Paper/demo sessions!For each session you can either a) attend the live Zoom session consisting of the talks and a live Q&A with the presenters during the last 15 minutes of each session and/or b) watch the presentation at your own leisure by clicking on the corresponding link and engage with others via slack. Remember that some presenters have opted to only have their presentation available during the session which means you will have to attend the Zoom session to see those.
  3. Poster sessions!Watch those at your own leisure and don't forget to VOTE for your favorite posters by Nov. 20 (for details see Poster Award). The poster with the most votes will win the 'People's Choice Poster Award'. Remember that some presenters have opted to only have their poster presentation available on November 20th.
