陶瓷回复求分析

教授一天左右回了我的邮件（有CV），但是一直没看我的主页。
Dear ######,
Thanks for your interest in my research program.  Your background is quite impressive and in line with our research.  I should have positions next fall but I am not sure how many.  I would encourage you to apply and indicate me as a potential advisor.  Please keep in touch with me.

Regards,
