2025 Virtual AGeS Community Symposium

Wednesday May 7, 2025

Overview: The virtual AGeS community symposium is intended to strengthen the geochronology community and its networks and will provide opportunities for senior scientists, early career scientists, and graduate students to engage and interact. The 2025 symposium consists of two sessions with invited talks and AGeS project presentations, as well as breakout sessions to enable conversation about current challenges in the geochronology community.

Session 1: AGeS Successes and Geochronology Community Activities (Moderator: Emily Cooperdock)
