I've put myself in a sticky situation. One of my friends referred me for a quant internship in NYC and just for fun I went along with it. He already works there full time but he's also already finished his PhD. They flew me out last week for an interview and I recently got the offer... The main problem is not too long ago I picked my adviser and ever since he has been talking about how this summer would be my "bootcamp" for the research that I'll be doing. He never went into too many details of what I'd be doing this summer because we're still both busy with classes. This semester is the last of my classes so regardless of what happens in the summer I'll be able to focus on my research in the fall. I don't think I can pass up this internship because it's such a big opportunity but I also don't want to upset my adviser the first summer together. Normally, these type of situations wouldn't bug me but it's the timing of the matter that's the issue. Of course, I will have to tell him soon but I would like to know if anyone else has been in this type of situation before and what they did to control the damage. Also, my adviser can't kick me off his research, right? P.S. - Money isn't an issue at all so please don't bring that up.
