Some Context: Over the past year, I have built relationships with 2 of the professors at my university. In this case, I was referred to Professor X by Professor Y. The professors work in two related fields (physics) and are friends.
I worked with Professor X on some of my research a few months ago and it went well. Professor X is allowing me to help him with his lab research over the summer and I am honored to do so. Of course, it would not be an every day thing and we will be working out a schedule.
Consequently, I spoke with Professor Y about a summer spot before starting my research with Professor X. Nothing was formalized here and I haven't spoken to Professor Y since beginning my research. However, I am very interested in helping Professor Y in her lab this summer.
My Question: Would it be seen as poor taste to ask Professor Y about helping in her lab this summer? In my email I would explain that I would also be working with her colleague.
I don't want to jeapordize my position or my relationship with either one of them, so, would it be considered "double-dipping" to help with both of them? If it is, would this have any adverse effects?
One option would be to ask Professor X if he would be alright with this. I am not sure about this option because again I don't want to put our relationship on weird terms.
This is undergraduate level, in the UK.
