I also agree. Rankings are BS. I just want to note that I am not selecting advisors based on their status or Nobel Prize. I am basing it off of research I find interesting, which probably should not be the sole criterion. @Micecroscopy, you seem to be very knowledgeable on the process of selecting an advisor. I really am not aware of the best way to assess my choices. All I want is to have a productive and enjoyable time during my PhD. What do you believe are criteria for narrowing my choice of faculty ? Lab size never seemed to be something I considered but I probably should. Which additional labs do you recommend I look at MIT or Rockefeller ? I am overwhelmed with the number of faculty and would appreciate any suggestions. I definitely agree that I should reach out to more faculty and students to better educate myself. Thank you for the amazing advice so far ! I really need it.
