I am communicating with a person in the U.S. who is about 40, and holds a university professor position, while I am a prospective student. Usually he would address me with 'Hi, MyFirstName!', and he has signed in many ways - from the official 4-line signature to simply his first name. Does it mean that he expects me to address him with only first name, too? Or I should better continue with the formal 'Dear Mr. FamilyName'? Is it ok to use 'Mr.' to address a professor at all, or 'Prof.' is better?
Thanks in advance. Bubr.

Hello Bubr, I will pretend that his name is Bill Smith for these examples. I think that you should use Dear Prof. Smith for now, and wait to let him tell you if he wants you to use Dear Bill .
