I will be applying for postdocs soon (in the US and Europe). I think I have a profile that is competitive, and I want to do a postdoc at a top place where my advisor did his postdoc (and continues to collaborate with his postdoc advisors). It has sort of been a childhood dream of mine to go to this place, and hence I am set on going there if I can get in.
My advisor thinks that it is a bad idea for me to try and go there, because it doesn't "look good" if I go to the same place where my advisor did his postdoc. He thinks that in order to get a tenured position some years down the line, I need to "separate" myself from my PhD advisor and his collaborators, and do something different on my own. He recommends that I in fact do a postdoc at other schools that are not highly ranked, but which have good people working in my field. I suppose his assumption is that getting a tenured position has little to do with the prestige of the school where you do a postdoc.
I was hoping to get opinions on this here. Does it really look that bad if I work with my advisor's collaborators?
