I am applying for a Ph.D. position in a research group. On the group's webpage, the leader of the group has asked to send him CV and Motivation Letter if someone is interested in a Ph.D. position.
I have prepared the documents, but I am wondering that what should I write in the email by which I will send him the documents?
Should I write about why am I interested in his work?
Should I talk about my educational background?
Or just simply say "Dear Professor, Attachment is my application for Ph.D. position in your group?"
