To piggy-back on the original question, I'm working on emails to send to faculty I would like to work with, and I'm wondering what I should put in the subject line of the email. Maybe I'm overthinking this, but I'd love any advice you all can give. Also, how have you all approached the issue of contacting multiple faculty in the same department? My best guess is to send individual emails and include a line saying "I have also contacted Professor X, as I am also interested in the research s/he is conducting on ...". This is assuming that the two faculty have similar research interests. How does that sound?
