I will be applying to PhD programs this fall. I have encountered a small setback: sometimes when I email a professor at a program I am interested in, I get no reply. I send a formal, polite, inquisitive email with what you would expect: a little bit about me, my research interests, explaining why I am interested in the program and them in praticular, and asking if they are taking on new graduate students. About half of the professors I have emailed do just not bother to respond. Is anyone else experiencing this?
