Glad to see you received a reply to your post.
I was going to follow up Joe and say that if you don't get any replies to flush out these ideas a little more and then follow up directly with a faculty member that you think is doing similar work. It often helps to see more detail on what a student wants to write / research about and what roles you see each collaborator taking. For instance, do you plan to take the lead and just need the faculty as a sounding board and some writing assistance or will it be a larger commitment of the faculty members time?
Book chapters or conference presentations are sometimes a good way to start a writing relationship with a faculty member (even though we ultimately prefer peer-reviewed journal articles) because they typically have a call for proposals in which you have weeks or months to flush out an idea in a proposal. The bottom line is that some people write together better than others. Once faculty and students establish a good working relationship together, it is that much easier to keep writing together.
Keep these conversations going!
