Yes. I work as a research associate at the University of Texas at Austin's McDonald Observatory
No. Not yet, anyway.
Well, not really. I like to think of it as taking on the pedagogical role of professor, voluntarily assuming the mantle of educator to the public, only without the salary. Or something like that.
Maybe. I won't do your homework for you, so please don't send me your homeworks questions and hope that I'll answer them for you. But I am willing to help point you in the right direction and to try and clear up questions you may have.
I can be very slow in answering email. Maybe I'm traveling, maybe I'm extraordinarily busy, maybe I've been swamped with email, maybe I'm being lazy. I will read all the email I receive, but I can't promise to answer them all.
It's not impossible to figure out, but I like a marginal buffer of anonymity. If you have any doubts as to my credentials, I'm happy to provide them. But I also value some semblance of privacy, even if it is a false sense.
