Letter to a professor

Hello!
I need to write a letter to a University professor to have some fundamental information for my degree thesis; he teaches in a Pennsylvania University and - through internet - I found out that one of his courses deals just with the subject I chose. But since I don't know him nor I can be sure he will give me an answer, I don't know how to present myself; moreover, I'm not used to writing formal letters. Can you help me?

Thank you.


PS: Maybe I made some mistakes but I'm not english, I am italian.

Sure, I will help you.

We can either do it here. Or you can write to me privately at

We'll create a great letter for you.

I look forward to helping you.
