Several team projects have been defined during our first meeting, and have been reviewed at the second meeting. The following four projects have been selected for continued team activity:

1. A Dynamo-based Model of the Galactic Magnetic Field

2. Signature of Field Reversals and Detectability in Observations of Other Galaxies

3. Universal Prior to Extragalactic Cosmic Ray Production

4. IMAGINE: A Bayesian Framework

These projects are expected to be finalized within 2017, and are presented and discussed at a follow-up workshop taking place at the Lorentz Center in Leiden, the Netherlands, during March 20-24, 2017.
