I've heard a lot about different schools having stellar reputations in certain subfields of physics, and that this likely matters more for career advancement than how "highly ranked" the school is overall. My question is, as someone who isn't currently plugged in to an academic community, how can I find out what a particular school is known for within the active research community? I'm asking very generally, but in my particular situation I don't currently have professors of my own that I could ask. Just the internet. For very well-known institutions it's easy enough to find out by word of mouth on the internet, since they are constantly under discussion, but I'm having a lot of trouble getting any detailed info on smaller state schools. Thanks!
