Ph.D. going back to school- How to introduce yourself/Email signatures?

[jvhdjbvhdj]

For those already with their Ph.D.s, how do you introduce yourself to professors/faculty when going back to school for a MS or MBA program?
 

Do you put the title in your email signature line?

Not that I have done this, but I imagine I might think about it differently in an MBA vs. MS. The MBA is all about networking and making connections, so putting my past education out there seems like it would be more relevant and helpful, if only for my PhD institution's name factor. For an MS, especially in an unrelated field, I imagine I wouldn't really advertise it or put it in my signature, but it might still come up in conversation and I wouldn't hide it, obviously. I don't see a reason not to bring it up as part of a "get to know you" conversation with faculty, you know, where you might talk about your background, where you're from, what you did before starting the program, etc. I assume at least some of them would already know because you'd report your previous education as part of your application.
