I am a third year PhD student co-supervised by supervisors A and B. I am starting a visiting researcher exchange in another university for three months, where I will be supervised by C.
I agreed with C on weekly meetings, which makes sense to me. But I know B wants to join (B was clearly upset several time because he missed meetings with C), and then it is weird to exclude A. However, I really don't want to have all my meetings with all three senior people as I know it is not going to be productive for me.
How should I manage my meeting schedule? I would be fine meeting A and B only once a month, but I'm afraid it would be badly received, especially by B.
