This past year I put in an application to a federal agency (US) for a post-doctoral fellowship and collaborated on it with a three profs/research scientists on the proposal. If funded, one of them will act as my post-doc supervisor and the other two as collaborators, all bring necessary skills and methodological capacity to the project. The project idea was my own that I had before meeting or discussing it with these collaborators, I chose to work with these people because they are researchers whose work I was familiar with and they are located in a city I'm interested in living in.
I have accepted a different post-doc since that application was submitted and I expect that application to be rejected because it was still a bit rough when submitted and it's a pretty competitive grant. Since I took the other position, I won't be doing this project with these collaborators in under this recent application. This is my first time as part of a multiple collaborator application, so I am wondering:
Who has ownership of an idea after grant rejection/do all members of a proposal collaboration have to be informed of any member independently moving forward with an idea from the proposal?
