I'm at a conference and I really enjoyed a plenary lecture by a speaker. His work resonated with some of the stuff I have been working on myself.
I have a Journal Club presentation coming up soon in my lab and I'm planning to present a few of his recent papers along with other perspectives in the field. Would it be ok to ask for a selfie at the conference dinner to put in the presentation?
In general, is it acceptable to ask scientists for selfies? I doubt that it matters, but the field in question is protein chemistry.
