The new NSF CAREER solicitation is out, and there's one major change: PIs can now include faculty-level collaborators on the budget as Senior Personnel (or as consultants). However, you'll still want to be very careful that the collaborator's role in your project is not central. The NSF CAREER is all about the PI and building her/his career, so it must be clear that the project is the PI's vision and that the PI is the central mover of the project. We'll discuss this more in the March issue of the Research Development & Grant Writing Newsletter, out March 15th.
