• ML4H 2021 is composed of several types of sessions accessible primarily through either a live stream or through the interactive Gather.Town platform.

Live stream

  • Keynote presentations
    • Keynote presentations are made available through the live video feed embedded on the front page of the website ( These presentations are grouped into sessions of one to three speakers each. A live discussion session based on audience questions will take place following the playback of each of the presentations in the session.
  • Spotlight presentations
    • Spotlight presentations are shorter talks that highlight exceptional submissions to the symposium that will again be hosted on the live video feed.
  • Rocket.Chat
    • During the live stream, all attendees can post messages in a Rocket.Chat window available on the website below the live video feed. Session chairs will relay questions to speakers during the associated question and answer session and post announcements. Questions directed towards the organizers may be posted to the #helpdesk channel within Rocket.Chat. Details on how to create your Rocket.Chat account can be found below.


  • A variety of events are hosted through the Gather.Town platform. We provide a general overview of the space at the bottom of this section. The Gather.Town space is accessible at link. The password to access the Gather.Town space will be shared with all registrants on the day of the event and will also be presented on the live video feed.

  • Poster sessions

    • Two poster sessions will be held in the same Gather.Town space in designated rooms at the top of the main hall. This year we are awarding Best Poster Awards, and all attendees can nominate posters for the award using this form.
  • Research round tables
    • There will be a one hour interactive session in the Gather.Town space dedicated to guided topical research discussions with the community. See this page for more details!
  • Raffle
    • All participants will be eligible to earn tickets in a raffle on the basis of their participation in the symposium. Each participant will earn one ticket for their registration with additional tickets available by participating in poster sessions, round tables discussion, and exploring the Gather.Town space. See this page for more details about the raffle.
  • Breaks
    • The Lounge area will be available during all the breaks (both social and lunch) for attendees to socialise, meet and greet. We welcome you to do so! This year we have also included an escape room dungeon (accessible at the bottom right of the space) that can be done in groups or individually. Links or portals back to the main space are provided.
