This is the situation. I'm a 2nd-year PhD student in Computer Science. The research group I belong to is very large, and during my first two years I have worked with many different people from the group, and also gathered a lot of contacts from other universities. In fact, I haven't really met my supervisor, let's name her Alice, for anything besides administrative stuff.
Now, I have been working on something with professor Bob, who works in a different university. Most of the work has been done by me, and since Bob is now out of time he said it was better for me if I continue this work with Alice. The thing is that I've been doing this pretty much on my own from the beginning, and I know I could finish it on my own as well. Also, as I said initially, my group is very relaxed in terms of student-supervisor relation, so I'm thinking of just continuing the project on my own and submit a single-author paper to X conference.
My specific questions, given the above, are the following:
- Should I pursue this on my own and just do it without notifying my supervisor? (it's important to say that in my group this happens often, but not for single-authored papers; i.e. a lot of students work with many other professors somewhere else without notifying their supervisors, and that's all fine).
- If you think I should talk with my supervisor instead, then how should I approach her? "Do you want to get involved in this" or "Can I work on this on my own"? (maybe it's relevant to say that my supervisor has co-authored some papers with me in which she hasn't really done much, not even the first-core idea, so maybe the same principle should apply here?)
I know this is very much dependent on how things work at my place, but I would love to hear the advice from other researchers as well.
