AGI projects are projects proposed by AGI members and endorsed by the Steering Committee. They should present first project ideas for strongly collaborative, genuine Ataxia Global projects, and should be translational in character, focussing on trial-readiness.

Would you like to submit a project? Please send your project proposal to ataxiaglobaloffice[at] using this template.

Please note  that AGI is not a funding organization.
