Hello. I run a Michigan meetup group based in Livonia. We have about fifteen people from the Detroit and Ann Arbor areas. If you give me your email, I will add you to our list.
I don't remember anyone who I'm sure is at the university in particular right now except for Sniffnoy. You can private message him here under that name, or I can relay a message if you want.
I live in Ann Arbor, and there are a few more Ann Arborites who attend Scott (Yvain)'s meetup
I'm interested in gauging interest in a LessWrong group at UM -- probably a Facebook group, as opposed to an official University club.
