There is one exciting job opportunity that I am willing to apply. The dean, I think, may know me because I have met him in a couple of conferences and I have been on a discussion panel once (as a Ph.D. student) in a conference which his department organized.
But he is a big shot, and he may know a thousand young aspirants like me. Will it be wise to send him an email or will it give a bad impression that I am trying to cajole him?
