The Annual Meeting event lasts 4 days, but AAAS staff, the program committee, disciplinary sections, a local committee, and others work hard all year to put on the best event we can! Make sure you don’t miss a deadline—see what’s happening to develop the Annual Meeting all year round.

In response to the community focus on COVID-19, the Annual Meeting team is looking to modify the scientific session proposal submission dates. With the shifting timeline in mind, we need committed reviewers to assist in evaluating session proposal in a prompt manner.

Full information about the 2021 Annual Meeting and our planned adjustments will be posted on this website. As we are now planning on having a longer submission window, we invite any interested session organizers for scientific sessions and career workshops to contact us at meetings@aaas.org to set up a virtual one-to-one consultation session.
