**I am currently at work on a new book,
and unable to respond to many of the messages
I get while I’m focused on research and
writing. If you’d like to reach me, please
include one of the contacts below so that
someone sees your message. Once I’m out of
focused-writing mode, I’ll be able to respond to
more messages. Thank you!**

(**NOTE: I enjoy getting questions from students,
but because of the volume I’m afraid I simply cannot
respond to most of them. That said, feel free to email.
I treat it like a lottery: if one pops up when I’m free,
I’ll answer. If I can’t get to it, my apologies.)
