Hello--I'm new here and I'm just sort of tacking on some commentary to this thread. I hope you don't mind!
I wasn't sure what the protocol was as far as contacting professors, either. I think I eventually wrote to someone at admissions and asked. They were very friendly and said to go ahead and contact the two professors who seemed to specialize in my particular topic.
I wrote Professor 1 and Professor 2 an email and heard nothing from Professor 1, but Professor 2 sent me a reply, which went to my junk mail folder (eep!). It was friendly and basically said he was about to go on holiday, but the subject sounded interesting and could I get back to him in early Jan.? I wrote back to say thank you so much--I would get back to him. He replied from a different, personal email to say fine and have a good holiday.
At the beginning of this month, I let the semester start (here), and then emailed him at the personal email--would he consider taking a look at my proposal now? No reply. I let a few days go by, then emailed him at his school email. Did he have the time to look at my proposal? Nothing.
Not sure what to do. My emails could be getting stuck in his spam filter. I've checked my "junk mail" folders over and over, just in case his reply went in there. Nope.
He seemed a very nice guy, but either he hasn't gotten my email, he's very busy, he's a bit scatty, it's normal to go weeks without replying to someone's email in his world, or he's been hit by a bus.
Should I try again? Should I start over with Professor 1?
