I am a junior postdoc (1st year) part of a program committee in an international conference. As a member I have been assigned with several papers that I would like to delegate to subreviewers.
I have in my network researchers who are also postdocs but, they could be regarded as senior. Is it rude, or weird, to ask them to subreview a paper? If so, should I try to find PhD students or other postdocs in my range? If not, to what extended may I ask for a subreview?
