Here is the situation: I am looking for a PhD in a field somewhat different from the field of my previous studies. I have several research groups in this area in mind and they have a very large number of researchers each.
Being kind of an "outsider" to the field, I don't really have a basis to know which ones of the Professors in the groups are going to be better advisors for me, since reading the publications of each professor (among more than 100 of them) would take me an immense amount of time.
I had previously read (I think it was some answer in this forum, but I couldn't find it again) that in those situations a good approach would be to send an email to the director of the group, state your main interests and see if he can point you to maybe one or two professors who might be willing to advise you. The problem with this approach is that these research groups are huge and really important, so I'm anticipating that the director of the group isn't even going to read my email!
What would be the best approach here?
Thank you in advance.
