Prize & Plenary Speakers

Why Attend: Share & Discover Research

There will be a wide range of Workshops, Splinter Sessions, Town Halls, and contributed sessions along with an engaging exhibition space representing our community and the institutions and companies that support our research. Plenary and prize speakers, including the Russell lecturer, will present their talks in Pasadena. #AAS240

As much as we want this summer meeting to be as big and busy as a normal winter meeting, the physical space available at the Pasadena Convention Center and at our meeting hotels is insufficient to accommodate all possible sessions, including some proposed Special Sessions, Workshops, private and public Splinter Meetings, and Meetings-in-a-Meeting. We apologize if some proposed sessions will need to be turned down for this meeting due to space limitations, and we encourage all proposers to also consider the winter meeting in Seattle in January 2023 (AAS 241) as an opportunity to host such sessions.
