How rude is it to ask a potential PI for their CV? I think I made a dire mistake a few days ago. I asked a potential PI for their CV (I wanted to get a full record of their credentials along with the information I could find about him on Google Scholar and his website), but I was met with a curt response telling me I should look at his website and papers. I felt really, really bad after that. I sent him an apology e-mail, saying I meant no disrespect, and will look at the materials he suggested.

For context, I am trying to decide between two reputable graduate schools for an EE PhD, and I am interested in a particular person at both. One guy had his CV publicly available, while the other did not (the one I may have offended). I naively thought I could ask for a CV since I've seen professors post theirs. I thought this could help me decide.

I'm going to wait a few more days to make a decision because I don't want it to seem like I intentionally provoked him to make it easier for me to pick an option.

Does the guy despise me now? I'll be seeing him in the next few years (these particular people know each other and work together, and go to the same conferences). Is there any way to undo any damage I might have caused to his impression of me?

Edit: Thank you everyone for your input. I will try not to make this mistake in the future.
It would be a strange person who starts “despising” someone for making an innocuous social faux pas. In novels one reads about such people, but real life people are, by and large, more reasonable.

I can only speculate, but I suspect the professor was mildly annoyed and/or amused by your request, told about it as a funny anecdote to his spouse later that day, and has by now forgotten all about it. The fact that he bothered to answer your email, and that the reply was polite, even if curt, suggests that he wasn’t terribly offended.
