Organization and People

The science component of the GEM Workshops are led by a volunteer Steering Committee. To promote transparency and provide an informal guide to existing, new, and future members of the Steering Committee, a document of GEM Steering Committee Best Practices was developed. This document, updated in October 2019, is available here.

We are attempting to record past personnel here: Former Personnel
