I met a Dr at the open house in the department and was soo excited about his research interests,
he gave me his card and asked me to contact him, which do you think is better phoning and asking for an appointment or emailing?

and what should I mention ?

what exactly are you supposed to say?
what are the most common reasons for supervisors to turn down students ?

can everyone share their stories please about finding supervisors?

sorry but i'm realy nervous about it ! :$
