GEM Grid-Enabled Measures Database Logo

Welcome to GEM!

This site, sponsored by the National Cancer Institute, supports teams to identify, evaluate, and gain consensus on the use of common measures for basic, clinical, or epidemiologic research. The process is supported through collaborative Workspaces and custom surveys.

Participation using a Workspace is by invite-only. If you received an invitation to participate in an initiative, you'll first need to log-in with your current credentials or set up an account if you haven't already registered. If you are interested in using GEM with your team, please contact Richard Moser (moserr@mail.nih.gov). Additional information about GEM can be found on the NCI website
