How do I respond to an email from a potential PhD supervisor who was positive but short? I recently contacted a potential PhD supervisor expressing my interest in working with him. I attached all application materials (personal statement, CV, etc), as he requested on his website. I received a prompt reply that he is accepting graduate students for the upcoming semester and to let him know if I have any questions. How should I follow up with him, and what sort of questions are appropriate to ask at this stage? I submitted my formal application to the program soon after receiving his reply.
Ask for a phone/skype call to discuss research interests, and to see if the two of you would be a good fit.


  Hi Prof X., Would you be available for a phone/skype call next week to discuss research projects and to see if I would be a good fit to be your advisee? Thank you!
