Urgent Call for Nominations: Research Grants Committee Member-at-Large

By: Rebecca Taormina , 9 months ago

At the close of Committee Nominations on 15 June, we did not receive any nominations for the Geochronology Member-at-Large position on the GSA Research Grants Committee. Each year, graduate research grant proposals are submitted in geochronology and related fields, and GSA needs qualified reviewers to ensure these proposals receive the attention and expertise they deserve.

We’re asking members of the Geochronology Division to consider stepping up and nominating themselves for this important volunteer role.

🔹 Position: Member-at-Large, Geochronology – Research Grants Committee
🔹 Term: 1 December 2025 – 30 June 2028 (3 years)
🔹 Time Commitment: Proposal review season runs March–May; committee is inactive the rest of the year.

The Nominations Portal has been reopened through Wednesday, 18 June. To access it, please contact Macie Schiller (mschiller@geosociety.org) for the temporary password and with any questions.

This is a vital opportunity to support graduate students and contribute your expertise to the future of geochronology. Please consider nominating yourself today!
