Each day will have the following format plus a few short breaks:

  • Virtual discussion rooms with the oral presenters
  • Virtual poster session to include:
    • 90-second lightning talks for each poster to begin the session

Early Career Scientist

This year, for the first time, the eGMAC Organizing Committee and GML Awards Committee announce the Early Career Scientist award for the best in oral or poster presentation. A group of judges will use the following criteria to identify the winner: logical flow of the paper, verbal delivery skills, and preparedness to answer questions. The winner will be announced within 2 weeks after the end of the eGMAC meeting.

Early Career Scientist (ECS) is defined as a student, a Ph.D. candidate, or a practicing scientist who received their highest certificate (e.g. BSc, MSc, or Ph.D.) within the past seven years. The seven-year period can be extended to allow for periods when the scientist was not working in science because of, but not limited to, caring and/or parental responsibilities, disability, personal illness, community obligations, or national service.

A career panel for early career scientists will be held on Wednesday, May 26 at 10:30AM Mountain Daylight Time. A link to the Google Meet will be available on the agenda for the Oral Session on Wednesday.


The eGMAC Organizing Committee is pleased to announce two awards for the 2021 eGMAC: Best Presentation (awarded daily), and the Early Career Award (one award for the entire conference).

The presentations will be judged on the following criteria:

  • Timing
  • Clarity
  • Effectiveness of Illustrations
  • Organization
  • Logic
  • Audience Engagement
